Step-by-step instructions for the manufacture of iron doors with their own hands. Metal doors with their own hands: how and with what you can do the technology of manufacturing metal doors with their own hands

The armored doors of Chinese production presented on the market in most cases only look efficiently. They are produced from a thin metal metal, the thickness of which rarely exceeds 0.8 mm, and it can be opened with canning opening. Therefore, if you need a really durable and reliable design, it is advisable both from an economic point of view and in terms of efficiency to make it yourself.

Preparation of materials

Before starting work, you must perform measurements of the doorway and sketch a schematic drawing of the design. With standard width (800-900 mm), the door can be made single, and with a wider opening, it is advisable to manufacture a collection framework - an additional sash is added to the side.

The metal door consists of 3 main nodes:

For the manufacture of welded doors, the following materials are needed (the amount is determined by the dimensional size of the structure):

Corner 50 × 50 × 5 mm - for the door frame.
The profile square pipe is 50 × 50 and a thickness of at least 2 m (you can use the corner of the corresponding dimensions) - for the frame.
Metal sheet thick from 2 to 5 mm - for the canvas.
Steel loops (2-3 pcs.) - The amount depends on the weight of the door.
Insulation - foam or mineral wool.
Lock.
Material for decorative sheat (at the discretion of the owner) - plywood, lining, veneer, plastic panels, etc.
Consumables are electrodes (selected depending on the steel used, the diameter is up to 3.0 mm), the discs for the grinder, drill.

Step by step making door frame

Dimensions of the box must be less than the opening - 20 mm gap is provided between the ends of the walls and the design. This will correct the position of the door and avoid skew when it is installed.

Taking into account these gaps, corners are cut and laid out into a rectangular design on a flat plane (welding table or pre-tedded to the goat flatness).

The corners of the box should be equal to 90 ° - are checked using a joinery and measuring the length of diagonals. The design welding and the subsequent sweeping of the welds flush with the surface of the corners (for dense fitting of the door canvase) is performed.

Build and welding doors

Taking into account the size of the box, the blanks of a square pipe for the manufacture of the frame are prepared. Gaps between the box and the door frame:

below and from above - 10 mm;
from canopies - 5-7 mm;
from the castle side - 6-8 mm.

As a result, the frame should be less internal sizes of a 20 mm box at height and 11-15 mm in width.

Phased door leaf manufacturing technology:

The chopped profile is laid out inside the box, the gaps are fixed (sweater materials are used - plates, discs for the grinder or wooden chips of the corresponding thickness) and are checked diagonal.
In one of the lateral profiles, a cut for the installation of the castle is made.
During the diagonals, the frame welding and stripping of the seams is performed.
The frame with the box is grabbed between themselves around the perimeter in 4-6 places.
Marking and cutting of the metal sheet. It is necessary to ensure a box of 10-15 mm, and from the side of the canopies - 5 mm. Taking into account the gaps between the frame and the box, these values \u200b\u200bwill be - 20-25 mm on the sides and 10-12 mm from the loop side.
On top of the metal sheet, the box with a frame is stacked.
Welding - performed by separate seams (length in the range of 40 mm, a distance of about 200 mm) The rotor from the middle to the edges is alternately from different sides of the door canvase. This will warn the possible deformation of the sheet and the design as a whole.
To increase the stiffness of the structure, horizontal and vertical profile blanks of a certain length are welded. In order to facilitate the decorative sheat, the door in the frame can be scored and consolidated wooden bars.

Welding door canopies and installation of the castle

Before installing the loops, the design turns over - the steel sheet must be on top. When installing canopies, it is important to comply with their alignment. The loops are welded to the leaf and to the box. Papers, with which the box and frame connected, cut off with a grinder. The door is revealed, and the canopies are boiled from the inside.

After that, all weld seams are carefully cleaned, and painting the structure. This will protect the metal from corrosion, so staining should be performed regardless of whether it will be done or the decorative finish will be performed.

On the door canvase, there are places for a locking well and a handle, drilling is performed. The mounting holes are drilled, the tank is cut into the tank, and the lock is screwed by bolts.

Also at this stage you can prepare a hole under the eye. It is drilled through the vertical profile in the middle of the door or shifts a little to the side and the opening is done only in the canvas.

Installation of metal doors

Mounting plates are prepared (6-10 pcs.) - You can make from the remaining sheet cropping, which was used for the door leaf. Details are welded to the box.

Installation steps:

Aligns horizontal and vertical door box. Fixation is performed using wooden wedges.
The level of door location is again controlled.
In the mounting plates and in the wall holes are drilled by a depth of 150 mm under the anchor bolts.
The first anchor is clogged on the side of the box where the loops are located.
Once again, the level of location is checked, if necessary, the design is equivalent.
The next anchor is clogged, the last thing is the average.
The fastening of the preliminary part is performed in the same sequence.
Metal doors are hung.
The gaps between the wall and the box are blown by construction foam.

After installation, you can proceed to the insulation of doors and finishing the selected materials.

The range of the modern building market is rich: in specialized stores it is possible. Metal, from wood, plastic, combined - all entrance doors have special specifics in making issues. The desire to independently make a metal door block occurs due to a number of reasons. For example, I want to get a design with specific requirements and additional materials, you need a high quality product at a minimum cost.

Tools and materials

The manufacture of a metal door with their own hands is actually applies to a budget version: create a product will cost much cheaper shopping of the finished design. Of course, to make a truly functional and stylish door, you need to own the instrument and have a certain experience in welding.

In addition, you will need competent drawings, high-quality materials and professional tools. We list the main components that are used in the process of creating a metal door composition:

Photo: Sealer for perimeter door

A list of the above materials and tools needed to create a metal door is approximate: the finishing solution depends on the type and the functional value of the future design. For example, in the manufacture of a tambourine or inlet door, it is best to purchase a thick metal sheet. You can also apply two sheet metal: in this case, the space between them needs to be filled with insulation.

Metal table workbench will be very useful

Another interesting material for the manufacture of the door, although not input, is.

Step-by-step manual instructions

The creation of a metal door consists of four main stages: the production of the frame, the production of metal canvas, the installation of fittings and the trimming of the product. A typical door design has a two-meter height and 90 cm wide.

Consider features in working on the creation of a metal door:

Frame . It is necessary to start making the frame after all measurements. The dimensions of the door box must be optimal: the metal frame must harmoniously enter the doorway, so on each side should be leaving a 2 cm clearance.

Blights . Between the frame and the metal web also need to leave the gaps, while the sheets should be slightly opposed to the edge of the frame. Welding work is necessary for small sections. The seams make no more than 4 cm in length, while the distance between adjacent seams should not exceed 20 cm.

Furnitura . For the production of loops, steel bars, having a diameter of 2 cm. The loops are welded to the canvas and the metal frame at the same time. Professionals are recommended to carry out a mandatory anti-corrosion processing of the product: with its help the door will serve not one dozen years.
Facing . You can use any favorite material: vinylister, PVC film, artificial leather, dermatin and others.

The main steps in the manufacture of a metal door do it yourself:

Conduct the measurements of the day and leave about 2 cm from the walls to the box to eliminate all the slots by mounting foam. In addition, such a gap will adjust the installation of the door in the event of a skewer.

Cut over the selected dimensions a corner of metal (approximate dimensions - 50x25 mm) and put it on the table for welding. Measure the length of the diagonals of the rectangle: they must be equal. You can start to welding only if all sizes are the same. So makes the door frame.

The finished box is measured by internal space, given the 1-centimeter clearance on each side of the perimeter. Cut the corner with dimensions 40 * 25 cm. In the lock profile to make a small slot using a grinder on the optimal level to install the lock level.
Simultaneously in the metal profile, wooden slats of optimal dimensions are clogged. This is done to simplify cladding.

Also, for the convenience of welding, the loop profile is recommended to immediately weld to a metal box and hinges. It is necessary to ensure the perfect coincidence of the loop and the door frame: for this carefully, the distance between them carefully. Under this condition, hang the door will easily.

Check: Parallel to the profiles of the canvas and boxes, after which the remaining door canvase profiles are inserted into the latter.
Then the metal sheet is welded. At first, the canvas measured: on each side, the door should have 10 mm on the door, while on both sides of the castle - 15 mm. The sheet is cut according to the size of the sizes, stacked on the product from profiles.

Initially, the loop part is welded from the back of the sheet in the inner cavity, then weld the canvas around the perimeter.
The preliminary band is welded from the inside of the metal canvas. For better strengthening of the door design, you can welcome special ribbies.

Conduct stripping welding seams and paint the product. It is recommended to make the door coloring even if in the future you will be facing it. Additional coating will avoid corrosion.
Mount locks in the number of two pieces. To do this, the hole is drilled in the corner to enter the riglel, then a slot for fastening the lock in the metal canvas is formed. You can cut hole and for the door lock.

Conduct door facing. It can be seen with planets or panels of wood, pound PVC film, repeating wood texture, or, for example, use leathesum. Many just paint the cloth and then weld to it interesting forged decoration elements. You can also use curly metal sheets or soft elements.

Among other types of metal doors are highlighted with durability and reliability. They are installed at the entrance to the house or staircase, where there is an increased protection. With the help of simple tools and equipment, each person will collect a metal door in one day. This requires also certain materials and knowledge.

Is it possible to make metal doors do it yourself

Reliable metal doors have long won consumer sympathy. They are used everywhere where additional protection is needed: in houses, garages, apartments, warehouses. Accordingly, the demand market and the market of proposals, a great diversity of finished steel doors can be found on the pages of newspapers and Internet resources.

The market presents a variety of types of metal doors.

However, many masters prefer the doors of their own manufacturing. Their advantages are to smaller financial costs and independent choice of design and materials. These factors allow you to assemble the door of any form, including non-standard options, and also give confidence as a finished product.

Thin steel frontal surface of ready metal doors cuts out without much effort

An independent assembly of a metal door requires not only special equipment, but also certain skills. This is especially true of welding connections. To impose a seam of necessary quality, you need skill and definite skill. The cost compared to the factory door will be 30-35% lower, but the quality may be higher.

Metal doors manufacturing technology

In the manufacture of metal doors, the main focus is on reliability. This factor depends on:

design of door leaf and frame;
materials used;
installation quality.

Reliability also implies the strength and durability of doors. Additional devices - closers and electronic eyes - make the construction of a construct more comfortable.

The varieties of door loops and locking devices allow you to choose the necessary components depending on the specific situation.

All these innovations are used for independently manufactured doors. First of all, when drawing up a project, it is important to think in detail all the elements included in the future design, and find the necessary materials. At the same time, it is necessary to take into account the technological sequence, the order of assembly, installation and finishing of the door block.

Drawings for the manufacture of metal doors with their own hands

To create a working drawing, you need to do the measurements of the doorway. Sketch is applied on paper in the selected scale. With the help of roulette, the width, height and depth of the day are measured.

Parameters of the doorway: sh-width, in-height, T-depth

There is a specific standard for metal doors. It is undesirable to do the dimensions of the door canvase more than 200x90 cm. This is due to the fact that the weight of the structure increases and, accordingly, the requirements for the quality (or quantity) of the loops increase. If the doorway is greater, it is more expedient to install an additional upper or side unit. The upper unit is often equipped with glass inserts for additional lighting. Side can be swollen or deaf.

Drawing must reflect the design features in detail

All these nuances are reflected in the drawing. Dimensions of the box are taken to lay taking into account the assembly gap, which allows you to set the design in a horizontal axis. It is subsequently filled with foam. To adjust the position of the door and eliminate the distortion, enough clearance is 2.5-3 cm.

For a uniform distribution of the mass of the door leaf on the box, from 2 to 4 loops is used. Canopies can be an inner or exterior design. More often use outdoor loops. The distance from the edge of the canvas to the loops from above and below is 15-20 cm. If the door is heavy and there is a need for an additional suspension, one or two auxiliary are mounted between the main loops. The drawing mark the exact location of the canopies taking into account their own sizes.

Support ball inside the sleeve softens the work move

Any door is equipped with ribs of rigidity. They are metal corners or pipes of a four-headed section, located along, along or diagonally a canvas. With their placement, two factors are taken into account:

the location of the castle and the door handle (for the convenience of mounting the rib ribs do not intersect with the place of installation of locks);
the method of warming the door (since the thermal insulation material is attached in the recesses between the ribs).

The insulation is located between the ribs of the rigidity of the door

In the drawing, you need to display outdoor door trim and the design units necessary for this. For example, if one of the parties is planned to be clapped, wooden bars are laying inside the canvas, which subsequently fasten the cladding. If the sash is covered with paint or laminated film, there is no need to install bars, but more attention is paid to the plane of the canvas. The surface is thoroughly polished, removed metal flutters, resulting during welding.

Equipment and materials for making metal doors with their own hands

After the working sketches are completed, you need to prepare tools and materials. Here is the main list of equipment:

Electric drill with set rolled metal. The sharpening angle of drill must be 110-130 o, steel tool, increased strength, calene. For the manufacture of the opening, it is convenient to use the core.
With the help of a core and a hammer prepare a metal drilling point
Turning or screwdriver with a set of necessary nozzles, including with cruciform and flat slots.
Welding machine, preferably an inventory type. Electrodes with a rod thickness of at least 2 mm.
The power of the welding machine must correspond to the metal thickness of the door
Corner grinding machine (Bulgarian) and cutting discs. Also need one riding disk to remove metal influx.
Vice and clamps for fixing structural elements in the assembly process. The solution of the working planes of the tool is selected based on the size of the blanks.
Clamp reliably keeps the workpiece while working with it
Metal files with fine structure.
Work workshop or goat.
Merchant workbench simplifies and speeds up the assembly of the metal door
Roulette, square, marker (or chalk) and other measuring instruments.
The presence of a variety of tools accelerates the assembly process.
Hydraulic or laser level.

As for the materials, the set will differ depending on the design of the door. Here is a list for the standard product:

Steel (frontal) leaf size 1x2 m. Thickness from 1.5 to 3 mm. It is preferable to rolling steel, as its strength is higher.
Metal corner, 35x35 mm in the amount of 6 row meters. Other options are possible depending on the dimensions and the device of the door frame.
Corner takes on the main load and does not allow to deform the door canvase
The profile pipe with a rectangular cross section of 50x25 mm is 9 m. If the door is designed for the utility room, the reinforcement is used, which is welded to the canvas from the inside. At the same time, the step of the rigidness is reduced, the crossbars are placed more often.
Pipe size must match the thickness of the door leaf and insulation
Metal plates (2-3 mm thickness and cross-section 400x40 mm) - 4 pcs. (For mounting the door frame to the walls of the day).
Loops - from 2 to 4 pcs. In the "advanced" models insert ball bearing supports.
Bearings make it easier and prolong the work of the loop
Anchor bolts, diameter from 10 to 12 mm.
Mounting foam with a low expansion coefficient, quick-conchive.
For the directional feed of foam to the gaps, a special pistol is used
Primer, anti-corrosion coating. Well established a car primer.
Door furniture. Castle with overlays, pen, eye, closer (the last two elements are used as desired). The locks are selected in accordance with the doors' functions. Sometimes to increase reliability, battle structures with three-sided fixation of the canvase are installed. Installation is more complicated, but also hacking such a door is much more difficult.
Rigal lock fixes the door leaf from three sides

Step-by-step instructions for assembling metal doors

It is advisable to adhere to the following sequence of work:

Metal corners are cut on the specified dimensions. The blanks are laid out on the workbench rectangle on the form of the door frame. Control is carried out by a fitter coal and tape measure. All parts of the design must be perpendicular to each other. Diagonal lengths can be varied no more than 1.5-2 mm. The permissible error in the height of the frame is 2 mm. Connect the corners between each other at an angle of 45 oh.
The plates are immediately welded to the frame that will be attached to the wall.
The composite design is welded. At first, "tacks" are set up at all corners. Recent measurements are held. If all sizes correspond to the working drawing, the box is finally welded. For convenience, clamps are used. Corner seams are processed by a grinder.
Welding work need to be carried out in a well-ventilated room or on the street
When the door frame is ready, the exact dimensions of the door canvase are measured (repulsted not from the drawing, but from the specific size of the frame). From all sides, it takes 10 mm. For the manufacture of the sash, a corner is cut into, a longitudinal opening is made at the lock location. The grinding disk on the grinder is replaced on the cutting needed thickness.
Wooden rails are placed inside the metal profile. With their help, future finishing doors are simplified.
In order to weld the loops, the door leaf frame is embedded in the corners of the frame. The location of the canopies must be accurately measured and secured by clamps.
Before fixing the loops, you need to mount the door web frame
The installation of the rest of the sash profiles is performed if the doorway frame is a congruent box (minus the technological gaps) and the loops operate in the right mode.
A prepared metal sheet is brewed on the frame frame. It is cut in size with such a calculation so that 1 cm should be 1 cm on each side, from the lock side - 1.5 cm. Before welding, carry out the fitting to the frame on the frame. If the calculated dimensions are sustained, the design is turned over and start to steer compounds.
Metal sheet is welded to the frame on the inside
First of all, part of the leaf of the loop (from the inside) is attached. Then boil the canvas around the perimeter.
Mounted Plot. To do this, a feigned plank is mounted on the inside of the sash two seams.
Pretake provides reliability doors
On the inner plane of the canvas are installed and ribbon ribs consisting of profile pipes are installed.
The forging is carried out and stripping seams from slag. The reliability of welded joints is checked. All irregularities need to be smoothed. After that, the design is covered with anti-corrosion primer. Drying time is 24 hours.
Seams are cleaned with an angular grinding machine and a file
Installed lock, retast plan, then the door handle and the rest of the auxiliary fittings. When installing components, it is recommended to adhere to the instructions in the accompanying documents of products.
Insulation, sound insulation, decor of the outer and inner plane of the door canvas are performed.

Metal door - means to secure accommodation, so it is reasonable to observe precautions. Bulgarian, perforator, welding - these useful tools with negligent treatment becomes dangerous to human health and life. The use of individual means of protection - respirator, welder masks, mittens, etc. - Natural labor life, forget this is unreasonable. In addition, a fire extinguisher and a bucket with sand is needed in the welding area.

Heat insulation of metal door

In the cold period on metal doors sometimes appears icing, water drops or frost. This suggests that the design freezes. Warm air indoors enters the metal surface and cooled sharply. As a result, condensate is formed, which either flows or freezes and turns into a lot. So that this does not happen, the door canvas insulate. Previously, a synthetone or dermatantine was used, but it did not bring effective results. Today in the arsenal insulation includes:

styrofoam;
mineral and basalt wool;
polyurethane.

Styrofoam

It is considered a very good insulation, since in its composition contains 98% of air, "sealed" in plastic bubbles. The dignity refers to the convenience of installation, low price and absolute corrosion resistance. Most industrial manufacture doors are equipped with a foam or its modification - penplex. In addition to thermal insulation properties, the material is characterized by good sound absorption. The disadvantages include the slightweight and isolating a large amount of toxic gases during burning and heating. Therefore, it is not recommended for installation directly in residential premises. The perfect location is the entrance doors of garages, warehouses, multi-storey buildings.

Polyfoam reduces the thermal conductivity of metal doors in garages and utility rooms

Video: Warming of the garage door foam

This category includes basalt and glasswater. They differ in the original raw material - basalt is made from rocks, and glass gamble - from sand and glass stretched into thin long fibers. There is no significant difference in the thermal insulation properties of the noticeable difference, but the wool from the glass is more environmentally friendly. And the one and the other material is characterized by high fire safety and convenience of mounting.

When laying mineral wool inside metal doors, it is necessary to comply with certain rules. For example, it is impossible to flicen mats between rigid ride - it lowers thermal insulation characteristics. Circling the material is needed with an accuracy of 1-2 mm.

Mineral insulation are produced both in the form of mats and in the form of rolls of various thickness

An essential disadvantage of mineral wool for the insulation of a metal door is considered hygroscopicity. The fact is that with a large air temperature drop from two sides of the door, the dew point shifts into the inner space of the canvas. This leads to the fact that the condensed excess moisture is immediately absorbed by the fibers. Over time, water accumulates and heat insulating characteristics decrease to 80%. You can avoid such a scenario using an additional vaporizolation film, which is fixed throughout the sash area. The hydrobrier neutralizes the effect of moisture accumulation, but there is no complete warranty. It is for this reason that the insulation of mineral wool is recommended in the doors that are not in conditions of significant temperature difference. For example, at the entrance to the apartment.

Polyurethane, or inflatable insulation

Pretty expensive, but effective technology. The inner cavity of the door flap is filled with polyurethane foam. Frozen polyurethane is a synthetic substance that is not subject to corrosion, an excellent heat insulator. The complexity is that special industrial equipment is needed for inflated, combining a diffuser and compressor. But the use of foam from domestic splashes is too expensive.

Polyurethane coating is not afraid of water, is a solid hermetic layer

Regardless of the material selected, the preparation for insulation consists in laying the location of the roiber of rigidity. Specialists recommend placing them in such a way that the insulation is reliably held inside the sash without additional fastening. That is, the crossbars have not only vertically or horizontally, but also combine them so that the insulation does not ask the insulation.

Vata tightly stacked between ribs inside the door leaf

Stages of mounting insulation on the door leaf

Specialists advise to lay insulation in the door in a horizontal position - on the table or goats. The pledge of successful thermal insulation is the care of the entire plane, minimizing the slots. The process is performed before sewing the inside of the web:

The dimensions of the frame cells are measured.
Cut blanks from insulation with an error of a maximum of 2 mm (largely).
The material stacked in the sash:
- if the insulation is used by foam, several points (4-5) of liquid nails are applied to the surface of the workpiece, the crops arising from the mounting foam;
- with the insulation of the mineral wool, the waterproofing film is pre-settled on the entire door area, and with the release (reserve), then the insulation is laid out and covers it with another layer of the film, the edges of which are folded into a single "cocoon", only after that it is sewn out the door outside (to enhance impermeability The air edges of the membrane carefully sink scotch).

Warming door box

For good isolation, it is necessary to warm and the door box. The method depends on the frame design, which can consist of a all-metal framework or from a hollow profile. Make it easy. Polyurethane mounting foam from a domestic spray gun poured inside the profile. If necessary, holes over the diameter of the tube are dried on the surface, which blooms polyurethane. It fills out all the free space.

The internal cavity of the frame is filled with mounting foam

The all-metal box will not be able to insulate in such a way, so you need to carefully treat the clearance of the clearance between the frame and the doorway.

Innovative means of insulation of the metal door is the insulating paint of the "Actor" series, produced on the basis of modern nanotechnology. The composition includes microscopic ceramic balls (several microns size). A layer of paint in 1 mm is equivalent in its heat insulating characteristics of 5 cm of foam. The disadvantage is a fairly high price and a difficult application on the metal surface.

Noise insulation of metal door

An important property of the entrance door is the ability to restrain noise from the outside. Metal does not help in this regard. Even, on the contrary, it helps strengthen sounds. Therefore, the door is complemented by special internal and outer coatings, which reduce the level of penetrating noise.

Outdoor coating

It is carried out with the help of sound-absorbing and vibration insulation materials. These include:

polysterol;
vibroplast;
bitoplast;
bimast.

This synthetic coatings are a cloth that actively quenches any sounds and vibrations.

Sound absorbing materials consist of several layers of different density

The order of work is as follows:

Material must be spread over an insulated surface and smooth out. Some species are equipped with a glue layer, they are enough to free from the protective film and press the door plane.
For others you need to clean and degrease the cloth. Then evenly distribute the waterproof glue, cover the surface with the material and withstand the time to completely dry. The pasting is preferably carried out both from external and from the inside.

Installation of the seal

Means is simple but efficient. Previously, felt used as seals, today there is a wide range of finished rubber and rubber products. There are no difficulties with the installation, you just need to remove the protective coating and gently glue the profiled strip along the perimeter of the sash. Its width should not be more than 25% of the size of the reference bar of the door frame. The thickness is chosen in such a way that the seal decreased in a compressed state (with closed doors).

The sealer consists of rubber tubes of a special cross section

Finishing metal doors

Outdoor door decoration performs two important tasks. Hides an unsightly appearance of a bare metal and protects the cloth from the effects of adverse factors. It is especially important to protect the steel surface from excessive moisture, as this may cause corrosion.

The choice of finishing materials is huge. But the most popular are:

mDF panels;
kervinil;
array of wood.

The microfrase fiber (MDF) is a mixture of wooden and carbomid chips compressable under conditions of high temperature and pressure. The material retains the color, texture and tactility of wood, but in strength and elasticity is not inferior to plastic. The big plus of the MDF panels is their low price. Nevertheless, this type of finish belongs to the "premium" class and from the point of view of aesthetics is not inferior to a natural array.

Entrance door, trimmed by MDF, it is difficult to distinguish from the natural massif

Professionals also celebrate a number of other MDF advantages:

high heat and sound insulation;
increased fire resistance, fire safety;
the combination of high strength and ease of processing;
resistance to the influence of biological factors: mold, fungus, dampness;
environmental purity, the stoves are not toxic and harmful chemicals.

In retail chains, you can find four types of MDF panels:

painted by RAL dye;
composed on a polymer basis;
laminated panels;
veneered products.

In addition to products in the form of sheets, there is a wide range of additional decorative elements of the doors - platbands, good, etc.

Kervinyl is the appearance of the outer finish, made of artificial materials imitating genuine leather. The same group belongs to the vinylist and dermantine. When compressing technology and operating technology, cladding retains its properties for a long time. Kervinyl - champion among low-cost ways to protect doors from noise and supercooling. Easily washed with conventional cleaning agents.

The disadvantages include flammability of material and defenselessness before vandalism. Drape the door is similarly accepted in the interior. Contact with outdoor and straight solar rays quickly leads to a loss of color and gloss coating.

One of the solutions of the metal door finish in the middle price range is the anti-vandal film sash tip. This wonderful remedy is not produced in Russia, so the price is high. The most popular is the film from Israel Vinorit. PVC coating has a variety of coloring, texture and thickness. Resistant to ultraviolet radiation, mechanical damage and effects of fire.

Natural array - the most expensive type of finish for iron doors. The overhead panel is made by gluing wood sawn timber and their further processing: grinding, milling, polishing, etc. For production, expensive woods are used - oak, beech, red tree, alder, ash. As a rule, the shape of the release of the panel from the array is a lining of 18 mm thick. This allows you to enhance the surface with various "plots". Often, the outer cladding of the metal simulates the Filöncutic texture of the sash. It is possible to apply ornaments, drawings and other decorative elements. In the factory conditions, wood is not only covered with paint or varnish, but also impregnate with special compositions, thanks to which the material becomes resistant to adverse effects of the atmosphere, does not dissipate and almost lit.

The array is beneficial from other finishing materials:

elegance of the appearance;
absolute naturalness and environmental friendliness;
durability;
increased indicators in terms of thermal insulation and sound absorption;
the possibility of restoration.

Oak coating over the years is only beautiful

The entrance metal door, lined with natural wood, is a symbol of respectability. Most often occurs in expensive restaurants, five-star hotels, solid organizations and offices of large companies.

Production of steel doors: relevance and feasibility of business + methods of organizing production + registration of entrepreneurial activities + manufacturing technology + list of equipment and raw materials + analysis of room requirements + recruitment + marketing plan + capital investment and payback.

Doors, including steel, is that product that is unlikely to ever become unclaimed. If some finishing materials or other building materials are in demand with varying success, then the doors are just a component of housing, which will always be needed.

That is why the production of steel doors is a promising business idea that is easy to implement in Russia, although competition in this area is relatively large.

To organize such a matter to almost everyone who wants to be done, because the manufacture of doors is not very complex from a technological point of view.

In this article we will tell how steel doors are manufactured, how in demand they are in the Russian market, and how to organize a profitable business itself.

Will there be relevant business on the manufacture of steel doors of Russian production today?

As we have already noted, it is difficult to find a more popular object in every house than the door. After all, they protect our abode and non-beetles and unscrupulous citizens.

This is especially true of the entrance door, which must be made of durable material, to allow their owners to sleep hard and calmly, not worrying that something happens to the house.

Today, steel doors are very popular and, despite the fact that they are many in the Russian market, such production can be a profitable and competitive business.

This is facilitated by several factors at once:

First, high demand is the basic condition that affects the fact that the doors market will never fully be filled.
Secondly, the production of steel doors is a simple occupation, which requires a medium-sized investment, which allows them to produce them at reasonable prices. Namely, the affordable price of the doors of Russian production makes them such competitive among foreign manufacturers.

Of course, there are many competitors in this area, because there are large enterprises manufacturing steel doors, and small, "garage" workshops, where doors are produced in a small amount.

But, in any case, you can take a place in this niche and you. It will help to find your consumer and your segment some "highlight" of your company.

It may be:

The unusual design solution of the steel door is now in the trend a variety of new items and a unique interior.
An acceptable price is quite a lot of elite products on the market, but people need more budget options.
Non-standard forms and dimensions - not only rectangular, but also arched doors are used.

Non-standard steel structures

The main consumers of your business can be several categories of citizens:

Private developers.
Tenants in large office centers.
Construction hypermarkets.
Owners of apartments in new buildings.

It is also noteworthy that steel doors are in demand throughout Russia, and not in some separate region. Therefore, a business can flourish regardless of where his founder lives.

The main condition that needs to be performed during work in this area is the high quality of products manufactured, which will show the consumer that the steel doors of Russian production at an affordable price is a good alternative to foreign brands.

What ways can you organize the production of steel doors in Russia?

Steel doors, as a rule, have the same purpose - they are used as an entrance door to which highly high demands are presented.

But, despite their identical purpose, production technology can be different. And what way you will produce steel doors, directly depends on what volume you want to produce, and what start-up capital you expect.

Depending on all the above factors, it is possible to organize steel doors in three ways.

№1. Opening a large enterprise.

Large, large-scale doors manufacturing enterprises involve their production in the amount of 200-500 units per day with a fully automated production line.

Such lines work, almost completely replacing manual labor. All processes are automated, which increases productivity and reduces the amount of defective products.

But such equipment is very cumbersome. To establish it, you will need up to 2 thousand square meters. m. Square. In addition, it will be very expensive - will require from 5-7 million rubles. investment.

It is advisable to open such an enterprise only if you have such a significant starting capital and at least some experience in this area.

Sample automatic production line

№2. Organizing small production.

Small, medium in size of the enterprise to organize much easier. For arrangement you will need less area and cheaper equipment, which will combine automated processes with manual labor.

On the one hand, it allows you to save on the purchase of equipment, and on the other, it is additional payroll costs.

In small enterprises per day, you can make from 10 to 50 steel doors.

Number 3. Realizing a home enterprise.

"Garage" enterprises, despite the presence in the market of large manufacturers, are also in demand.

All processes in small enterprises are performed manually using a hand tool. This type of production allows you to produce up to 3 doors per day, which is in the power to bring good profits.

To open a mini-plant for the manufacture of doors, more people will need, since automated processes will be absent.

What kind of production method choose you - decide on the basis of your financial capabilities and skills, but pay attention to the last two options.

Large enterprises must have a very good marketing strategy and, in addition to the doors, they need to produce a lot of accompanying products to pay off.

Therefore, we will analyze the small and medium-sized businesses that it is easier to organize and make it possible, without even having experienced in business.

How to organize the production of steel doors from a legal point of view?

The manufacture of steel doors is not too high-artistic process. But due to the fact that they must comply with certain requirements from a building point of view, before the opening of their case, it will be necessary to familiarize themselves with a certain list of literature and get a construction license (SNiP 11-23-81).

Be sure to pay attention to the following GOSTS:

In addition to registration of a license, the legal registration of entrepreneurial activities is also waiting for you.

For the production of steel doors, you can register and as an IP, but it will be better to choose. It will allow you to cooperate with large construction networks and hypermarkets, and position yourself as a qualified enterprise.

Register as Ltd. is simple enough: you need to come to the IFTS at the place of finding a business, submit relevant documents and specify codes for the OKVED of your future activities.

Codes need to choose the following:

As for the package of documents required for registration, it consists of 5 mandatory papers:

Passport of a citizen of Russia.
Charter LLC.
The decision of the founder about the establishment of the LLC or the minutes of the meeting of the founders.
Statement in form p11001.
Receipt of payment of state duty.

As a tax system, it will be advisable to apply the general tax system - the OSN.

Steel doors manufacturing technology: phased guide

You can two main ways - pipe and coal and profilegic. The latter is most popular, in which curved laminated profiles are used for manufacture.

The production technology of inlet steel doors with profilegic equipment consists of 7 main steps:

Preparation of metal.

It is necessary to start the technological process with the detection of defects of the metal coating and its inspection on the quality of the material.

Cutting blanks.

After the metal sheet is prepared, there is a markup on it, which in the future helps cut out the product blank from it.

Production and processing of blanks.

Cut blanks are sent to bending machines, where they form a profile for the door box. All workpieces are mandatory, that is, all the irregularities are eliminated to give them a neat species.

Also, at this stage, the holes of the future steel door are formed using special equipment, where the lock and accessories will be placed.

Welding door pastune.

With the help of welding machines (or welding robots in automated lines), all elements are welded to the frame, after which both sides of the door are fastened with each other. The material is placed between them, which performs the function of a noise insulator and seal.

Outlet door.

After the doors collected after the passage of all stages of production need to paint. Paint in this case performs not only aesthetic function, but also a protective, protecting metal from environmental exposure.

Saving steel door.

To give the door more attractive look and increase its wear resistance, it is customary to sow various materials that can be wood, veneer, leather, dermatin, MDF, wrought elements.

Installation of fittings and quality control of the finished product.

To avoid loud sound when opening and closing the finished door, depreciation material is glued at its edges, and the locks and accessories are embroidered.

After all the stages, each door undergoes a mandatory quality control, which helps to avoid the fastened product from entering the final consumer.

As a result, the passage of all stages of production we get ready-made steel doors, which in the context have the following form:

Equipment for the production of steel doors: devices for a small workshop and a small enterprise

Whatever enterprise you do not organize, you will still need equipment for the manufacture of products.

If this is a semi-automatic line of devices, its cost will be within 1.5 - 2 million rubles. If you are planning a very small business, then the hand tool will cost an order of magnitude cheaper - up to 500 thousand rubles.

So, for each methods will require such equipment for the production of steel doors:

Name	Cost, rub.)	Sample
Semi-automatic production line (for small enterprise)
Metal cutting machine (plasma or laser)	120 000
Listogibust press	1 500 000
Welding machines (devices)	100 000
Painting gun.	20 000
Compressor	2 500
Hand tools (for home business)
Bulgarian	10 000
Mechanical guillotine for metal cutting	140 000
Milling Machine	100 000
Lathe	90 000
Hand tool	5 000

To save a few on the purchase of equipment, rationally buy a used device. But at the same time, it is not necessary to try to save, buying poor-quality, too worn out techniques for the production of steel doors, because product quality depends largely on the devices themselves.

To place the equipment semi-automatic, used for small enterprises, will be enough 250-350 square meters. m. Square. For manual and mechanical equipment, you can find the area under the workshop of 100 square meters. m.

It is important that repair and other premises were repaired, and it was prepared for such production. Walls and gender should be fire-resistant, which will protect the enterprise from the fire when working with welding machines.

Since it is planned to produce frames and paint, and paint the doors, the placement under production needs to zonate so that some technological processes do not interfere with the other.

Highlight at your enterprise at least 7 individual premises:

For a warehouse of raw materials.
For a warehouse of finished products.
For the processing shop of sheets and their rental.
For assembly welding shop.
For staining shop.
For finishing shop.
For check space.

What raw material needs to be purchased for the production of steel doors?

Raw materials are an important element of organizing steel building structures, which will depend on the quality of the finished product.

Purchase of raw materials for this enterprise will consist of two parts:

the first is the purchase of material for door hulls,
the second is the acquisition of fittings for equipping steel design.

Of course, both the other raw materials should be very high quality. But the requirements for fittings are very overpriced, as high-quality locks are already 50% of the success of the steel door.

As raw materials for the production of structures you will need materials:

Steel sheet - thickness 2 mm (some manufacturers believe that the thickness of steel, the better the door will be, but this statement is erroneously, since each additional 2 mm is added the weight of the structure, and this leads to its rapid wear).
Mineral wool.
Electrodes.
Solvent.
Primer.
Paint.

We will also need materials for the trim. What exactly depends on your choice.

As for the fittings, it will be necessary to purchase the following names:

Locks.
Pens.
Loops.
Clamps.
Latch.
Latch.
Eyes.

How many employees should be gained to the staff to start work at the enterprise?

The number of employees needed to work in the enterprise will depend on what business you plan - small or medium.

If you want to start with a small amount of work, and plan to use mechanical machines and hand tools, then you will need to work:

Technologist who performs the duties of the manufacturer of production.
2 machine operators, monitoring the operation of milling and lathes.
2 workers carrying out different processes.
2 welders that will be directly occupied by welding doors.
1 installer, which will be engaged in installing the door.

The functions of the Director General, the Accountant and the manager in small enterprises can be performed by the owner.

If business is planned bigger, that is, medium-sized, it will be better to hire such specialists:

Accountant.
Technologist.
2 welder.
3 workers.
Installer.
Marketer.

If desired and here, accounting reports may take on the owner, but it will be better at enterprises better if a specialist will be engaged.

By the way, at least the production of steel doors is not a difficult process, it will be nice to hire people who have appropriate education or experience in such a sphere.

Since the equipment is not fully automated, qualified personnel will help reduce the amount of marriage and increase productivity.

Production Marketing Plan: To whom and how to sell steel doors?

To make a profit as soon as possible to make a profit, you need to take care of the establishment of sales and advertising channels.

Who will be your consumers, we found out in the beginning. It can be individuals and tenants, and building stores.

To find out about how more potential buyers as possible, use the following:

Develop your own website that will serve your exhibition hall and online store. To the site be colorful and functional, it is better to entrust it to creating experienced programmers and web designers.
Order printed products (business cards, booklets). Leave them in large retail chains, distribute passersby.
Let's advertise in newspapers, magazines, on TV and radio.
Collaborate with large construction hypermarkets, selling their products from them.
Use electronic newsletter to potential consumers.

In order to stand out among the other manufacturers, do not forget to consider the benefits of your company and tell about them to all customers.

Your business card should be quality and reliability, just so you can work clients and reputation.

How much will you have to spend on the organization of steel doors?

Since we analyzed both small, and medium businesses, we calculate the amount in this area and in order for another option.

Costs	Amount (rub.)
TOTAL:	1 100 000 rubles	2 600 000 rubles
	Small enterprise	Middle Enterprise
1. Registration LLC	18 000
2. Registration of the license	35 000
3. Rental of premises	15 000	37 500
4. Buying equipment	345 000	1 700 000
5. Purchase of raw materials	350 000	500 000
6. Payment of wages	165 000	190 000
7. Advertising	75 000
8. Other expenses (utilities, taxes)	100 000

And now we turn to the payback counting.

Approximate productivity of a small enterprise is 60 doors per month. Their market value ranges from 13 thousand rubles., Cost cost - 7 thousand rubles.

It turns out that, selling 60 doors per month, you will receive an income of 780 thousand rubles. Net profit will be about 360 thousand rubles. It is easy to calculate that with such forecasts, the company will be able to recoup already 3-5 months later.

The average enterprise can make a month from 200 steel doors. Given the same market value and cost, we find that income per month will amount to 2.6 million rubles. You will get about 1 million rubles for clean of them.

If you consider additional costs in the first month of work and for some time necessary to search for sales channels, we can calculate that the average enterprise will pay off in the first six months of work on the market.

Thus, we can conclude that the production of steel doors in Russia is a profitable, simple and fast payback type of business.

To start it, you need to competently think over the concept of an enterprise and try to find several sales channels at once. Such actions will help in a short time to return the money invested, thereby positively affecting the development of production.
