Roofing profiled sheet sheet dimensions. Decking: sheet sizes and types. Installation of the roofing cake is done in this way

Decking is a popular roofing material, which is a galvanized and corrugated steel sheet, on top of which a special polymer coating is applied.

Depending on the size, weight and manufacturer, the types of coverage and other parameters may differ, which ultimately determine the choice of corrugated board.

Given the wide variety of goods on the market, buyers ask themselves: what kind of corrugated board is needed for the roof? Will it fit for? What are the dimensions and markings in principle? We will answer questions and provide the reader with information that will be of practical use to him.

Marking and types of corrugated board

Finding out the main characteristics of this building material is quite simple. It is necessary to consider the inscriptions that are on each sheet - they are the same for all manufacturers and are standardized for the domestic GOST 24045-94.

According to this GOST, it is customary to distinguish the following types of corrugated board:

Important: despite the different types of markings, the use of profiled sheets is not allowed for a specific purpose.

For example, profiled sheets "C" can be used in roofing works, however, it is necessary to make a roof with a large slope, and must be very dense, if not continuous. The same applies to roofing sheets - they can be used to install fences, but additional cross beams must be installed.

To avoid such technological complications of the construction process, it is recommended to use sheets only for their intended purpose.

Scope of corrugated board

Often, different brands of corrugated board have similar characteristics, which is why you have to choose the material solely for the cost and appearance of the sheets.

We examined the most popular brands of corrugated board and compiled an appropriate table so that the reader could navigate the functional purpose of each brand:

Scope of corrugated board with characteristics

Based on the field of application, it is necessary to determine the specific parameters of the profiled sheets.

So, based on the parameters, you can use corrugated board for the construction of the wicket. Made and beautifully designed, it will fit perfectly into the surrounding landscape.

After the wicket has been installed, it is necessary to make a lock. The lock on the gate made of corrugated board can be very diverse. all possible locks for the gate are listed. The choice will depend on you.

Dimensions of the profiled sheet

Dimensions are necessary to determine the required amount of material for installation work. In addition, it is necessary to know the weight of the profiled sheets - in this way the maximum load is calculated and the type of battens that should be used to install the corrugated board is determined.

Length and width of profiled sheets

Consider the standard sizes of a sheet of corrugated board of the most common types:

To determine the length of the profiled sheet, you must look at the last digits in the marking on the product. The length of one sheet can be either 2.5 meters, or 11 meters or more.

Sheet thickness and wave height

The wave height directly depends on the type of profiled sheet. So, load-bearing and roofing sheets can have a large corrugation, the height of which is in the range of 35-44 mm. Wall sheets used for decoration can be 13 mm wide. Accordingly, the wave height of each next type will be 3-3.5 mm higher.

Thickness of sheets:

Sheets marked "H" have a thickness of 0.55 to 0.9 mm. Accordingly, the weight of one square meter of a sheet can fluctuate between 7.4-11.1 kg.
Sheets marked "НС" have a thickness of 0.55-0.8 mm. Weight - from 6.3 to 9.4 kg
Sheets marked "C" are the lightest and thinnest - the thickness is in the range of 0.55-0.7 mm, and the weight is from 5.4 to 7.4 kg

Sizes of various types of corrugated board

Conclusion

After all the above parameters, the reader will be able to determine which material will be optimal for certain types of installation work. It should be borne in mind that all the types and sizes given were compiled in accordance with the current GOST. When purchasing foreign professional sheets that do not have GOST certification, a deviation from the above characteristics is possible.

To select a brand of profiled sheet and calculate the need for this material for each specific object, you need to know what are the differences between the types of corrugated board. Different brands of roofing sheeting also have different technical characteristics.

There are not so many main characteristics of a profiled sheet, including roofing. These are the dimensions of the profiled sheet for the roof, its thickness, as well as the geometric dimensions and shape of the surface profile.

Dimensions of roof sheeting

The highest quality profiled sheet is produced in accordance with GOST 24045-94. The standard regulates, with millimeter accuracy, the main dimensions of the roofing sheeting and all the other technical characteristics listed above.

A very important advantage of the roofing sheeting is the size of the sheet. The capabilities of modern rolling mills, which produce profiled sheets, allow the production of products with a sheet length of up to 14 meters. Therefore, you can purchase a corrugated board for the roof, the sheet size of which will best match the dimensions of the roof of the building.

This is very important, since the use of profiled sheets of long length makes it possible to several times reduce the number of joints in the roofing. And this, in turn, greatly increases the tightness of the roof. If the length of the roof slope is less than 14 meters, then the roof covering will not have horizontal joints at all.

Among other things, the consumption of corrugated board is also reduced, since short sheets of roofing are laid with an overlap of at least 200 mm.

Unfortunately, the larger the size of the roofing sheeting, the higher the cost of its delivery to the object. Therefore, a professional sheet for the roof, the sheet size of which is more than 10 meters, is made only to order. Most often, in the construction of residential buildings, corrugated board is used for the roof 6m long.

The profiled sheet is easy to process and can be cut directly on the construction site with conventional hand-held metal cutting tools. But most manufacturers of corrugated board accept orders for their products indicating a specific length of sheets. The length of the corrugated sheet for the roof is set by the control system of the line for the production of corrugated board, and the profile is cut automatically, without human intervention. The length of the corrugated board for the roof can be from 0.5 to 14 m with a cutting ratio of 0.5 m.

Another important dimension is the width of the corrugated sheet for the roof. The standard width of rolled sheet steel, which serves as a raw material for the manufacture of profiled sheets, is 1250mm. But the width of the corrugated board for the roof entering the receiving device of the rolling mill will be completely different.

It should be borne in mind that the higher the height of the wave or corrugation of the profile, the smaller the width of the profiled sheet for the roof will be. In particular, the width of the C8 corrugated sheet is 1200 mm, and the width of the H75 corrugated sheet, made of metal of the same width, is already only 800 mm.

You need to know that the profiled sheet has two widths. One of them is a purely geometric value that can be measured with an ordinary tape measure. Another sheet size is called "usable" and "working" width. This size of the corrugated sheet for the roof determines how much of the length of the roof slope will overlap the corrugated sheet, taking into account the vertical overlap with the adjacent sheet in the same row. So, with the total geometric width of C8 corrugated board of 1200 mm, the working width of the sheet is 1150 mm. This point is very important to consider when calculating the amount of material required for the installation of roofing.

The thickness of the corrugated board for the roof

The thickness of the roof sheeting is a very important characteristic of the roof covering. The profiled metal sheet is made of metal with a thickness of 0.45 to 1.2 mm. The reliability of the corrugated board and the service life of the roofing directly depend on the thickness of the metal. The thicker the metal, the greater its strength and the longer it can resist corrosion.

But the thickness of the corrugated sheet for the roof significantly affects the cost of the corrugated board, since the greater the metal consumption of any material, the higher its price. Therefore, the decision of which thickness of the corrugated sheet for the roof to use in each specific case is made on the basis of calculating the load on the roof covering, taking into account economic considerations.

The thickness of the corrugated board for the roof also affects the weight of the corrugated sheet. One of the generally recognized advantages of a profiled sheet is its low weight and, as a result, the ease of installation of this material. The use of a thicker and heavier corrugated board increases the labor intensity and cost of installation work.

In addition, if a thicker and heavier profiled sheet for the roof is laid on the roof, the weight of the material itself will additionally increase the load on the supporting structures of the building. Depending on the thickness of the corrugated board chosen for the roof, the architects calculate the strength of the rafter system. Therefore, any changes in the weight of the roofing during the construction phase are highly undesirable without appropriate calculation.

Dependence of the characteristics of the corrugated board on the shape of the profile

As mentioned above, the thickness of the corrugated board for the roof significantly affects the strength and reliability of the roofing. But the main thing that determines the bearing capacity of a profiled sheet is the shape of its surface profile. The higher the wave height of the profiled sheet for the roof, the greater the load it can withstand.

The most popular roofing material is profiled sheet. To obtain a high-quality result, the dimensions of the corrugated board play an important role. Indeed, the market offers a wide range of such materials. Therefore, it is worthwhile to deal with this characteristic in more detail. The article will consider the dimensions and characteristics of the profiled sheet, its application.

Decking is a corrugated sheet made by rolling on a roll forming machine. With the help of such processing, they achieve on its surface wavy, trapezoidal or rectangular protrusions, called waves or ridges. The profiled sheet is made of zinc coated steel coils. The scope of application of this material is very extensive: the construction of fences, wall cladding, roofing, etc.
The main characteristics of the profiled sheets are regulated by GOST 24045–94. Materials produced in accordance with this standard are of higher quality. There are advantages to using profiled sheets, such as:

ease of transportation and installation;
corrosion resistance;
durability;
sizes for individual orders;
thermal stability;
ease;
variety of assortment;
moisture resistance;
reusable;
high strength.

Corrugated sheet length

One of the characteristics of a metal profile is its length. During installation, such sheets are stacked with an overlap. Because of this, 200 mm or more of their length is lost. In accordance with SNiP II – 26–76, the overlap size must be over 250 mm. It is better to use corrugated board with dimensions corresponding to the size of the roof of the building. Namely, the length of the slope. This will allow installation without horizontal joints, and will increase the tightness of the coating.

The standard material size is three to ten meters. This value should be a multiple of 0.5 m. On modern rolling mills, it is possible to produce a profiled sheet, the size of which is 14 meters. Due to the high cost of delivery, such sheets are only made to order.

Metal profile thickness

The next important characteristic for a profiled sheet is its thickness. The strength and durability of the roofing depends on it. The larger this parameter of the profiled sheet, the higher the specified characteristics will be. The corrugated board is made of galvanized sheets with a thickness of 0.45-1.8 mm. When choosing a material, it is important to take into account that, in addition to undeniable advantages, thick sheets also have disadvantages. The large thickness of the sheet leads to an increase in the cost of installation work and the complexity of assembly. In addition, the price of a metal profile depends on the thickness of the profile. The higher this indicator, the higher the cost.

Corrugated sheet width

An important characteristic is such an indicator of the corrugated board as the width of the sheet. It is used to calculate the roof structure. The width of the sheet depends on the height of the corrugation. The lower the wave, the larger the described dimensions of the metal profile. Sheets of standard sizes are produced in widths of 845–1850 mm.

When performing calculations of the required material for the roof, it should be borne in mind that this characteristic of the corrugated sheet has two values. One full, the other working. To ensure tightness, overlapping sheets are required. In accordance with SNiP II-26-76, the size of the overlap must correspond to the width of one corrugation. This reduces the overall width by about 40–80 mm.

Surface shape and stiffeners

Materials for roofs must be resistant to additional loads: gusty wind, ice, hail, snow weight, etc. The reliability of the coating depends not only on the thickness of the corrugated board, but also on the wave height. You can determine this value by calculating the distance between two adjacent waves. The lower the ridge, the less resistance of the profiled sheet to deformation.

For certain types of metal profiles, additional stiffeners can be formed on the upper surface of the trapezoid and / or between the waves. Due to the presence of such ribs, the longitudinal rigidity of the profiled sheet increases. Thanks to this, it is possible to increase the pitch of the truss system. Such a roofing material is excellent for buildings with significant static loads.

Varieties of material

Currently, the range of profile sheets is very extensive. According to the area of use, the profiled sheet is divided into the following types:

for roofing (load bearing);
for walls;
universal.

Roofing sheeting is the most durable of these types. For its production, the metal with the greatest thickness is used. Additional stiffening ribs provide increased strength of such a metal profile. In addition, the strength is due to the height of the corrugated board (over 44 mm). Due to its resistance to heavy loads, it is suitable for covering large roof slopes.

Standard dimensions of corrugated board for walls ensure ease of installation work. The peculiarities of this type are the smallest corrugation height, production from a thin galvanized sheet. The areas of application of the profiled sheet are fences, suspended ceilings and wall partitions. This type of profile is more economical. For this reason, with limited funds, it is also used to cover the roof slopes of residential buildings. The universal profiled sheet (supporting-wall) has a ridge height from 20 to 44 mm. Like the load-bearing one, it has additional stiffening ribs and is almost not inferior to it in strength. Due to the lower metal consumption, its cost is comparatively lower. Due to this, the universal metal profile is used more widely. It is used for roofs, awnings, fences, etc.

Metal profile marking

As mentioned earlier, to regulate the main characteristics of a galvanized metal profile, a standard has been developed - GOST 24045-94. This regulatory and technical document introduces marking for profiled sheets. This marking consists of an alphabetic and a numerical designation. Where the letter code means the purpose of the profiled sheet, and the digital code means the wave height of the metal profile.

Decking sheet dimensions described in GOST have the following markings:

For roofing:
- Н114, with a width of 600 mm;
- Н114, 750 mm wide.
For walls:
- C10;
Universal:
- HC35;
- HC44.

Today, one of the most popular roofing and facade building materials is profiled sheet, the sizes and colors of which are available in a wide range. In this article we will tell you why corrugated board has become so popular, and how it differs from similar building materials on the market.

1 Advantages and disadvantages of different brands of corrugated board

Over the years, the professional sheet has proven itself well. It is worth noting the following advantages of corrugated board:

simple and quick installation;
corrosion resistance;
light weight and high strength;
aesthetic appearance;
low cost.

The corrugated sheet consists of:

bases - sheet of steel;
zinc and phosphate anti-corrosion coatings;
polymer and ground coatings.

The profile sheet has its own markings, by which you can navigate what type of work it is intended for. There are three main types of building material:

Wall or facade with product marking "C", used for finishing areas with a small external load.
Universal "NS", suitable for any interior and exterior finishes.
Roofing "N", designed primarily for the construction and decoration of the roof.

Sometimes manufacturers change the standard markings for those designed specifically for their logos, for example MH, PC, as indicated in the technical specifications for these products.

2 What are the standard parameters of the profiled sheet?

The generally accepted and most demanded in construction are those dimensions of rolled metal that provide the greatest convenience during transportation and the least labor intensity during the installation process. The typical dimensions of the profiled sheet include:

material length;
overall (overall) and useful width;
sheet thickness;
height;
sheet weight;

Usually, the most demanded lengths are 3 and 6 m. The uniqueness of the material lies in its manufacture from a rolled type of metal, therefore, at the request of the customer, the length of the product can be almost any. But with a length of more than 12 m, some properties of the corrugated board may be lost.

For a different type of assembly, it is customary to purchase sheets taking into account the nuances of the structures being erected. It must be remembered that the total and working width differ by an average of 50 mm due to the technology of overlapping products (overlapping by one wave). Therefore, to calculate the optimal amount of material during transportation, the overall width is taken into account, during installation - the working one.

The thickness of the profiled sheet corresponds to the thickness of the initial material - galvanized sheet. The standard material is considered to be from 0.5 to 1 mm.

The choice of wave height (stiffeners) depends on the installation options and the expected mechanical load on the building material, also taking into account the weight of the sheet and its working width. Naturally, the strength of the corrugated board for the roof will be higher than that of the wall, because the loads it withstands are many times greater.

3 Roofing profiled sheet - dimensions of sheets for the roof

Profile sheet began to be widely used for roofing work, due to its advantages over ondulin and tiles - lighter weight and high strength provided by stiffeners. Roofing sheeting, the sheet sizes of which are the same for all manufacturers, corresponds to the generally accepted GOST or the approved technical condition (TU). These standards allow the use of this building material for any type of structure: industrial buildings, temporary facilities, large buildings.

The distinctive dimensional characteristics of the material for the roof are the thickness of the metal and the height of the stiffener. Given these indicators, there are several popular brands for the roof:

PK 20 with rib height 20 mm, total width 1140 mm.
PK 35, where the height is 35 mm and the total width is 1125 mm.
NS 44 and PK 45 with wave heights of 44 and 45 mm, respectively, and a total width of 1045 mm.
Н57 - height 57 mm and width 1050 mm.
H75 - 75 mm and 800 mm, respectively.

For all these brands, profile sheets of various lengths are produced. Depending on the configuration of the floors and the roof itself, lengths from 0.3 to 12 m are used. Also, this building material, in addition to the total width, has another important indicator - the working width (less from the total to 50 mm, depending on the size of the profiled sheet).

The external load that the material must withstand directly depends on the thickness of the sheet of the coiled steel used. The thicker the sheet of metal and the higher the wave (rib) of stiffness, the greater the load the material can withstand. Roofing sheeting with a thickness range from 0.4 to 1 mm is in the greatest demand.

This value is taken into account in the design of buildings and significantly expands the scope of application of the building material. A table of loads specially created for design engineers facilitates calculations, which affects the cost of the project, significantly reducing the cost of it. The thickness of the corrugated material affects another important technical characteristic of the profiled sheet - the weight of the sheet.

The small proportion of the building product has become one of the reasons for its popularity.

4 Wall profiled sheet - dimensions and weight of profiled steel

And facades are used for facing buildings, creating a layer of insulation and internal partitions. The most widespread is the profiled sheet, the dimensions of which are as follows: the width of the sheet is 1–1.2 m and the height of the wave is about 20 mm (for grade “C”).

The thickness of the metal sheet varies from 40 to 80 mm. The smallest rib height produced at the moment is 8 mm. Wall corrugated board is intended for exterior wall decoration and interior work. There are also materials with rib heights of 10, 15, 17 and 21 mm. Sheets with ribs over 21 mm are considered universal. On individual orders, some companies produce corrugated sheets with a thickness of less than 8 mm.

A demanded and useful width for walls is considered to be 1090-1150 mm, and the C15 brand is popular in a width of 0.8 m. The latter is often used for. Wall corrugated board weighs much less than roofing. This indicator varies from 4.45 to 8.37 kg of both 1 linear meter and a square of usable area.

Owners of country houses often choose a material such as corrugated board as a roof covering. It has long gained popularity in the construction of both residential and industrial and other buildings due to its durability, strength, ease of use, and aesthetically pleasing appearance. In addition, it is quite easy to make a roof from this roofing with your own hands.

Profiled sheeting is made of galvanized metal sheet by cold rolling and is supplied to the market in the form of profiled sheets of various shapes - wave, trapezoidal or triangular. The material is treated with a protective anti-corrosion agent, therefore it perfectly withstands the loads associated with atmospheric precipitation.

Classification

To make a high-quality roof with your own hands, you need to choose the right corrugated board for the roof. Sheets of corrugated board can have different thicknesses and bending heights, depending on which their purpose is determined:

Wall;
Roofing;
Combined.

The wall sheet is marked with the letter C and has a bending height of 8-21 mm and is used for cladding various non-residential objects, as well as fences and fences. The roofing sheet is marked with the letter H and has a wave height of 57-115 mm. Due to the highest stiffness of all types, it can be used simultaneously as a covering and a frame for a roof. The combined sheet is marked with the letters НС and has average characteristics - its bending height ranges from 20 to 66 mm. The material can be used both for cladding walls and fences, and as a roof covering.

Selection of corrugated board for the roof

The most suitable type of corrugated board for the roof is H, but HC can also be used with a bend height of 35 mm or more. The smaller thickness of the sheet of corrugated board type NS is not used as a roof covering, since it may not withstand snow and wind loads.

In addition to the bending height for roofing, parameters such as the thickness and width of the roofing sheeting are extremely important. The maximum thickness, as a rule, does not exceed 1.2 mm, and the minimum is 0.36 mm. The value of this parameter affects the strength and bearing capacity of the sheet, as well as its weight and cost. It is logical to assume that the higher the value, the larger all the parameters described above. It is recommended to choose the corrugated board for the roof in such a way that its thickness is not less than 0.5 mm.

The width of the corrugated board for the roof is an extremely important parameter due to the peculiarities of the fastening of this material: the installation is carried out with an overlap, and therefore they distinguish between the total and useful width. The general is the physical width of the sheet, and the useful is the distance that remains after the installation is made. As a rule, overlapping installation is carried out on the extreme strips of the roofing, as a result of which the dimensions of the corrugated sheet change. It is worth noting that some manufacturers supply corrugated roof sheeting with edge strips with a special profile that facilitates the installation of the material.

Popular brands of profiled sheet

There are a large number of different types of profiled sheets on the market, but not all of them are suitable for roof installation. The most popular types are as follows:

NS-10;
NS-15;
NS-20;
H-60.

Roofing sheeting of the H-8 type has a rather modest sheet size, and therefore it is more often used for the installation of fences and barriers. However, it can also be used to build a roof with your own hands in regions with low snow and wind loads. It can be either just galvanized or have a polymer coating of various colors.

NS-10 belongs to the combined type of profiled sheets and therefore has a universal application - you can make both a fence and a roof from it with your own hands. Due to the fact that the dimensions of this type of corrugated board have such features as the same width of the upper and lower corrugation, it is excellent for the installation of complex roof structures.

Profiled sheet of the NS-15 type is also universal and has a thickness of 0.4 to 0.7 mm. Its distinctive feature is its increased strength, and therefore it can be used not only for the construction of fences and non-residential buildings, but also for the installation of roofs, including complex structures. In addition, it has edge strips suitable for overlapping installation. The dimensions of this type of sheet are as follows: its length can reach 6 meters, and the useful width is 1150 mm.

The dimensions of the NS-20 type corrugated board, the length of which can reach 12 m, and the width is 1125 mm, also make it possible to use it as a supporting structure when installing a roof. This material can be used as roofing sheeting due to the large wave pitch of 65 mm. Due to this characteristic, it is not only well suited as a supporting structure, but also quite simple and easy to install.

The H-60 type profiled sheet is one of the most reliable options for roof installation, as it has a thickness of 0.7 to 1 mm and a corrugation height of 60 mm. These characteristics provide the material with high stiffness values, and therefore it can successfully withstand the largest wind loads and does not bend even under a large amount of snow, and, therefore, can be used even in the extreme north.

The width of the H-60 type sheet is 902 mm, of which 845 mm is the usable area remaining after overlapping installation. Its length can reach 14.5 m, which also has a positive effect on the ease of installation. This type of sheet is produced from galvanized steel and can be coated with a special polymer coating that provides additional protection against external influences and a wide range of colors.
