What is a metal tile. Types of metal tiles. Shiny Polyester - Handle with care

It is difficult to imagine a home without a roof. The roof saves from the cold, bright sun and precipitation. It is the architectural completion of the building. The right choice of material for its arrangement will be the key to the comfort of the inhabitants.

Metal tile - what is it?

A metal tile is a fairly modern type of roofing, it is considered relatively young, it was invented a little over 30 years ago. This is a type of roofing material that looks like its predecessor - ordinary tiles. For the manufacture of thin-sheet steel, copper and aluminum are used. The metal base is covered with a layer of polymer. By means of processing by cold pressure there is a profiling of a product.

It does not matter the type of structure and its purpose. The metal tile is optimally suited for a roof with an inclination angle of 15 degrees. The most common type of fastening is fixing to the crate. It is suitable for any climatic zones, well endure any weather vagaries. Strength and durability values vary by supplier. It is the composition of the raw materials that will determine the performance of the system. Positive customer reviews speak of a great future for this product.

What is a metal tile?

All material is classified according to a number of criteria.

Types of metal tiles depend on:

The components used.
The presence of a decorative layer and the method of its application.
profile type.
The principle of installation.

There is also a classification that characterizes the appearance and standard of the manufacturer. An example is a series "Elite" "Elbrus", "Beaver tail", "Venice". The metal tile has its own standardization, a system of symbols.

Main types of coverage:

From polyurethane. The covering is not afraid of an ultraviolet, chemical regents.
PVDF. The coating protects against mechanical damage.
Pural. It contains additives that resist UV rays.
Purex. The dye is great for the northern regions.
Plastisol. The serious thickness of the coating allows you to create a relief.

Worthy Supplier will always provide a certificate of quality. Manufacturers have the right to independently choose the dimensions of products: width, height, thickness may be different. But the most optimal dimensions: width 1.18 meters, height (length) - 4.5 meters. The thickness depends on the structure, the average is 0.5 mm.

How much does a metal tile weigh?

This is a lightweight material. The approximate specific gravity is only 5 kilograms per square meter, which is almost 8 times less than the classic version. This helps to reduce the cost of construction, the user does not have to invest a lot of money in a powerful metal structure under the roof.

How to choose a metal tile for the house

Any roof is a significant weight that the building structure must withstand. During construction, at the design stage, it is important to find out (calculate the weight) - how much the metal tile weighs. This will allow you to make a margin of safety, in advance to insure yourself against an accident. When deciding "which one to choose", study several proposed options, consult with experienced builders.

Advantages and disadvantages

Any material is a set of advantages and disadvantages.

Advantages of metal tiles

In addition to low weight and strength, it is necessary to name:

Environmental friendliness.
Ease of installation.
Availability.
Huge range of color solutions.
Possibility of installation over an old roof.

Cons of metal tiles

Among the shortcomings, it is important to highlight the likelihood of ignition (and burnout) of decorative versions coated with a polymer layer. Almost always laying requires the use of waterproofing for metal tiles. (You can read about waterproofing under metal tiles in our article -).

Noise from the rain.
High thermal conductivity.
The need to carefully select tools and fasteners.

Popular manufacturers of metal tiles and general reviews about them

The abundance of offers on the building materials market baffles the average consumer. The answer to the question "which one to choose?" always start with learning the manufacturer.

There are positive, real reviews about the GRAND LINE brand. This is a domestic manufacturer that has been operating on the market for more than 10 years. Products are purchased by ordinary buyers, heads of construction companies. The entire production process is automated, marriage is rare. The consumer is offered a huge range of metal tiles.

RUUKKI is a Finnish manufacturer that guarantees high quality standards at a reasonable cost. The product retains its original gloss for a long time, production facilities are located in many countries, including the Russian Federation. The creators are trying to orient the goods under the harsh conditions of Russia.

MERA SYSTEM is a Swedish company that invests a lot of its earnings in the study and improvement of its products. The company has been producing metal tiles since the first days of its invention. You can choose the best option for the dimensions and shape of the profile. The brand is difficult to fake, there is strict control at each stage of production.

Technologists and scientists are constantly improving the types of metal tiles. The product is seriously evolving, delighting all users.

Bottom line: which metal tile is better?

When choosing the best option, they proceed not only from cost and dimensions. It is important to take into account the size and step of the wave, the design of the rafters or battens. Much will be determined by the natural environment. If your house is located in a humid area, then use raw materials based on aluminum and copper. The steel version is more suitable for dry, stable climates.

If you are going to equip a store or an entertainment center, then it is important to pay attention to the appearance. It is the color and decorative coating that will make the building bright and attractive. Sheets treated with polyvinylidene fluoride resist corrosion and ultraviolet radiation well. Polyurethane coating will give the roof extra strength. The answer to the question "which metal tile is better" is a thorough analysis of the existing conditions and the study of the characteristics of each type.

Metal tile is a modern roofing material, which is cold-formed sheets of aluminum, copper or, most often, galvanized steel, imitating ceramic tiles in texture.

To protect against the harmful effects of atmospheric phenomena, the sheets are covered layer of polymeric materials.

Every year the volume of sales of metal tiles is growing, it is increasingly used in both municipal and individual construction projects.

Let's try to understand the reasons for such popularity, varieties and features of the use of this material. In this article you find out the size of a sheet of metal roofing and other technical specifications.

When talking about the geometric dimensions of the sheet, they mean three parameters: width, length and thickness. And now consider GOST metal tiles.

So, dimensions metal tiles for roofing:

Width — 116-119 cm, the working width of the metal tile is about 110 cm;
The length of a metal tile sheet is from 50 to 900 cm;
Thickness metal tiles varies depending on the type from 0.4 to 0.6 cm.

The width of a metal tile for a roof of any kind, brands and lengths, as a rule, is in the range from 116 to 119 cm. It is very easy to explain - the manufacturer ties the width of the metal tile sheet to the width of the raw material, which, in this case, is a sheet of metal.

The metal tile sheet is formed at the rolling mills of metallurgical enterprises, where unified equipment with standard roll sizes is used.

Much more variety can be found by looking at the list of possible lengths. Rolled metal entering the factories for the production of metal tiles may have length up to 9 meters This reduces shipping and handling costs. Of course, the installation of a roof from sheets of this size would be extremely difficult.

Therefore, the sheets that go on sale are much shorter. The length of the metal tile is set by the manufacturer and can be arbitrary, but most often one of the standard sheet sizes is used (all sizes are plus or minus 3 cm):

ultra-small - 50 cm;
small - 120 cm;
medium - 225 cm;
large - 360 cm;
very large - 450 cm.

Many firms also provide cutting services sheets in length according to the needs of the customer. One of the most popular types of metal tiles today is.

Metal profile: metal tile dimensions

The thickness of a metal tile is usually understood as the thickness of its metal layer. If the previous two indicators characterized exclusively ease of installation, then the thickness of the metal tile for the roof is also operating parameter.

It should provide an optimal balance between the reliability of the structure and its weight. This condition corresponds sheet thickness in 0.5 mm, it is also the most common. Metal tiles of smaller thicknesses are used in small auxiliary structures, large ones - in the case of a roof of a sparse frame of a large area and subject to high strength of the bearing walls.

Metal tile wave height and sheet profile

wave metal tiles call a vertical line consisting of conditional cells, and wave sizes are the distances between the centers of adjacent cells of two waves (step) and the distance from the lower to the upper point of one cell (height).

Most manufacturers use one of two standard wave steps - 185 mm or 350 mm.

Wave Size metal roofing is within:

from 20 to 30 mm - small standard height;
from 30 to 50 mm - average standard height;
from 50 to 70 mm - a large height (usually - only in expensive varieties).

A sheet profile is understood as a characteristic pattern formed by wave cells, a certain unique pattern. The profile is developed by the design department of the manufacturer and can be absolutely anything. The only requirement to the profile of the metal tile coating - compliance with your aesthetic views.

Advantages and disadvantages

To the main advantages of metal tiles can be attributed:

relatively small price;
big life time;
small specific weight;
stamina to the effects of atmospheric phenomena;
attractive appearance;
fire department safety.

The low cost of a roof is most clearly manifested in comparison with its main historical competitor - ceramic tiles. The mechanization of production, the possibility of simultaneous operation of a large number of production lines and the availability of the materials and technologies used make metal tiles a low-cost material to manufacture.

And considering reliability finished product, strength and impact resistance, it is obvious that in the ratio of cost to service life, metal tiles leave all other roofing materials far behind.

But just the appearance is often a stumbling block for people who are thinking about purchasing roofing materials, but do not have the proper experience in this. They expect some kind of ceramic tile roof surrogate, not realizing that it has long faded into the background not only in quality but also in design.

Modern metal tiles are made symmetrically and accurately, and the perfection of technological processes allows you to imitate any shape. So metal tiles are suitable even for projects with a distinct retro style.

In the case of fire safety, everything is more than obvious. None of the components of the metal tile is able to burn, smolder, somehow contribute to the emergence or spread of a flame.

Advantages of coverage

However, one cannot deny the obvious limitations metal tiles. These include:

material overrun during installation;
fast wear when the top layer is damaged;
relatively low sound insulation;
danger descent of snow layers.

NOTE!

The overspending of the material is explained by the fact that the size of the metal tile for the roof has fixed values, which inevitably leads to extra scraps metal tiles. This overspending is especially noticeable when covering roofs of complex shapes with many angles and bends.

It would be unfair not to notice that the same disadvantage common to almost all roofing materials, with the exception, perhaps, of ceramic tiles.

The most common type of damage to the top layer (polymer) are chips, cracks and delaminations as a result of mechanical damage, for example, during transportation, cutting a sheet or. In places where the polymer layer is broken, as a rule, corrosion occurs quickly., which is fraught with the loss of not only aesthetic properties, but also the tightness of the roof.
The sound insulation properties of the coating are a moot point. Noise isolation will be really extremely low if you mount the sheets directly to the frame. Then every drop of rain, not to mention hail, will resound under the roof. However, when using a soundproofing substrate and observing metal tiles, the soundproofing of a structure will in no way be inferior to any other type of roof.

Due to the specific shape of the leaf surface, snow layers can come off, which can be dangerous for the life and health of others. Solving this problem is very simple - just use .

Additional elements

They name the details of the roof that do not fulfill the purpose of the roofing material, but are necessary for fixing it, making joints and turns, removing additional structures, ensuring tightness, and removing excess precipitation. The main types of additional elements are:

- a profile in the form of a corner, a cornice, a semicircle or a complex shape, installed at the junction of sheets of metal on the upper ridge;
end plate- a profile in the form of a corner or a complex shape, covering the front and rear edges of the roof;
planks of external and internal corners- profiles in the form of a corner or a complex shape, designed to perform turns of the metal tile at an appropriate angle;
valley plank- a profile of a complex shape, providing the lower joint of the roof wings, as well as the removal of excess precipitation from this joint;
low tide- a profile in the form of a wide channel or a semicircle, located along the slope of the roof and performing the function of draining rainwater;
- a triangular profile that prevents the sliding of snow layers;
plugs- figured sheet metal products that provide sealing of joints of straight surfaces with surfaces of complex shape.

Additional elements

In addition, some sources indicate stairs, hatches, cornices, caps, chimneys, even insulation and self-tapping screws as additional elements. Of course, all this is necessary when installing the roof, but how to classify these positions is a moot point.

This coating is the material of the future, superior to most competitors in terms of economic, ergonomic and performance indicators. We hope that our article was useful for studying the main parameters of metal tiles, its properties and types.

Tiled metal modules have earned a good reputation among roofers and homeowners: in the photo and in reality, roofs covered with this material look presentable, and such beauty is relatively inexpensive. Sheets of steel that have undergone galvanizing and polymer treatment are durable and perfectly protect the structure from heat, cold, and moisture. But how long will a metal tile last? The length of the service life depends on many factors, but first of all - coatings.

workpiece thickness;
zinc content;
protective coating;
wave geometry and pitch specifics.

Also, the material can be grouped by size - length and width. This approach is not considered appropriate, since modules are sold per 1 m2, and sometimes they are made to order.

1. The thickness of the blank sheet.

One of the determining indicators of the reliability of tiles is the thickness of the steel. To date, its minimum value is 0.35 mm, and the maximum is 0.9 mm. Due to the high cost and low demand, products that are too thick are practically not produced. Variants of 0.5-0.55 mm can cope with potential mechanical loads.

2. Metal content of the zinc layer.

The level of corrosion resistance depends on the amount of zinc content. In modern coatings, the specific gravity of this element can vary in the range of 90-275 g/m2. In modules with a steel thickness below 0.5 mm, the metal content of the zinc layer often does not even reach 150 g/m2.

3. Protective layer.

The metal that has undergone galvanizing is coated with polymers on top. Tiles are based on:

polyester (polyester);
pural (polyurethane);
plastisol;
polydifluorite (PVDF or PVF2).

All of them have a rich color range, various texture variations, and an aesthetic appearance. Resistance to external influences, strength - the characteristics that determine how long the coating will last - they are completely different.

Polyester is not afraid of serious temperature fluctuations, the influence of UV rays. It is pliable, elastic and perfectly adheres to the surface of any materials. The big disadvantage is that it is inherently unstable even to the smallest mechanical damage, as a result of which a corrosion spot often forms at the point of contact with any object, which grows over time. The service life of such a roof will be short (with a protective layer thickness of 25 microns - approximately 15-20 years). But if you use improved polyester (Viking, Agnet, Velor), then the performance properties of the roof will increase, and it will last ten years more.

Pural is a type of polymer material that has excellent protection and durability factors. Being applied at 40-50 microns, this fiber is able to withstand temperatures from -50° to +120°. The durability of shingles with pural is above average and reaches half a century.

About the plastisol-based option, we can say that this is the thickest coating (200 microns), the degree of protection here is the highest. There is a significant drawback - vulnerability to ultraviolet rays. Direct sunlight, falling on the roof of such a plan, after a while forms swollen and discolored areas on it. In this case, the metal tile will not last long - a maximum of 20-30 years. By avoiding intense radiation, it is possible that the roof will retain its original appearance up to 60-70 years.

If PVDF, a mixture of polyvinyl fluoride and acrylic, acts as a finish, then the sheets are endowed with an interesting feature: they repel any type of moisture and liquid dirt. The anti-corrosion effect of these modules is quite strong, as well as their UV resistance and color stability. With a thickness of only 27 microns, this type of metal tile is sensitive to mechanical deformations. With the right attitude and care, the average (declared by manufacturers) service life is 30-40 years.

4. Wave geometry and step width.

The construction market offers various variations of the tile profile. The most basic are:

Monterrey;
Cascade;
Banga;
Andalusia.

Monterrey is the most demanded type of metal tile. Resembling a beveled wave in shape, which is the reason for the similarity with traditional ceramic roofing, it is popular not only for covering private sectors, but also for the construction of office, retail space, and the reconstruction of historical buildings. In addition to the standard profile, it has modification versions:

Maxi - characterized by an increased wave width, which creates a "spacious effect" and visually makes the roof larger.
Super - characterized by the optimal location of the "groove" (at the top of the shaft and at a decent distance from the edge), so that moisture does not penetrate into the roof; Supermonterrey modules seamlessly fit together, and the picture as a whole turns out to be monolithic.

The cascade is considered an economical material: it is characterized by a large width, and its shapes are straightforward, like a chocolate bar, which facilitates installation and pre-installation work. Any building acquires strict proportions and sophistication. It is famous for various variations, but the Maxi profile is more in demand. It is outwardly similar to the classic version: the only difference is a wider wave pitch (by as much as 50 mm).

A variety of Banga metal tiles is a relatively young coating. It has a bizarre shape and a large wave height. But it is precisely due to the significant bulge and three-dimensional visualization that the roof acquires a special aesthetics.

Tiling Andalusia in the last five years enjoys increasing popularity. Its design features are a deep profile and the presence of Z-shaped grooves on 2 sides, which cause reliable adhesion to neighboring modules, as well as tightness. There is no need to match the color of fasteners to the general background of the sheets, because they will be hidden by the flooring.

for the roof of a residential building, use steel products 0.5-055 mm; if it is planned to finish canopies, canopies, auxiliary blocks, then modules can be taken with a smaller thickness indicator (for example, 0.4-0.45 mm), in regions with increased snow load it is better to use thicker canvases (0.7-0. 9 mm);
the zinc content should be limiting - this will help the metal tile resist corrosion;
when choosing a topcoat, it is wiser to give preference to pural or plastisol, but in the case of the latter, direct sunlight should be avoided (that is, it is suitable for garden buildings or country houses, cottages located in the shade of trees, higher structures); and living on the coast, it is ideal to use PVDF, because polydifluorite perfectly repels water;
if the roof is not characterized by a sharp slope, it is better to choose Supermonterrey type profiles, where there are convenient “grooves” for collecting moisture; in other situations, any form will do;
for high-rise buildings, the beauty of the top will help to fully reveal Banga;
with the difficulties associated with choosing a color, physical foundations will make the task easier: if the region is famous for its hot climate, it is more expedient to prefer light shades, since they heat up less.

Price

How much a metal roof will cost depends on many circumstances: the area and complexity of the work, the cost of installation services, the need for additional attributes. But the main factor in determining the price are:

thickness of steel and zinc layer (the thicker, the more expensive);
the quality of the protective coating (polyester is the cheapest option, polydifluorite is more expensive);
profiling technology.

The cost by suppliers is indicated not per unit of length, but per m2.

Metal tile is a roofing material that made a real technological revolution in the 80s of the 20th century. Imitates traditional ceramic, but much lighter in weight and more convenient to install and operate.

It is made from sheet metal-roll with a thickness of 0.45-0.5 mm by cold stamping.

The resulting characteristic wavy surface is called a profile.

The sheet has a high-quality multilayer protective and decorative coating on both sides.

Ease of manufacture and installation and rich decorative possibilities make it suitable for roofing of multi-storey buildings, private houses and cottages.

Life time metal tiles fluctuate from 15 to 50 years depending on the quality and production technology.

The choice of metal tiles is not so simple, it seems at first glance, and first of all it is worth weighing all the pros and cons.

Advantages obvious when compared with ceramic tiles:

Less weight per unit area - such a roof is more than 10 times lighter than a conventional one;
Economy- cheaper roofing by lightening the load-bearing structures;
A simple scheme for coating;
Fast mounting speed and a simple device ;
high sustainability to mechanical influences;
It is easy to choose the optimal roof;
The best insulation against moisture penetration and wind;
More varied and bright color range;
Fading-resistant decorative layer - the roof of your roof will retain a juicy and bright look for a long time;
Many : , drip, wind bar, etc.

Flaws are not so critical and can be compensated by strict adherence to the installation technology:

When installing roofs of complex shape, it remains a lot of scraps, which cannot be reused;
Increased noise appears in case of violation of the installation technology and the absence of a soundproof layer;
Large heat loss, but they are compensated by good;
Do not forget about the same.

Susceptibility to corrosion in areas with a broken protective layer- joints, cuts and holes for fasteners. This drawback is eliminated by the use of high-quality sealing material for fasteners, and careful staining of places.

What types of metal tiles exist and their description

Types of metal roof tiles are classified.

How to choose a metal tile for a roof?

Which metal tile is best for the roof and is right for you? By adhering to these rules when choosing, you will never go wrong:

If you have non-standard roof shape - use a modular metal tile- you will have less scraps.
Check for markings on the back of the sheet. It contains information about the metal from which it is made - pay attention to its thickness, zinc content.
Check availability of certificates conformity and manufacturer's warranty.
The higher the profile height, the less snow it holds.. A roof with a high profile will also look more impressive. Don't forget to install.
Polyurethane coating (Purex, Pural Matte) is designed specifically for northern latitudes.
The coating based on matt polyester (PE) tolerates high temperatures and high humidity and is therefore suitable for mid-latitudes and southern regions.
The protective and decorative coating must be solid without peeling, cracks, scratches and signs of corrosion.
Check the maximum bending angle at which the surface does not leave cracks and damage - this is usually indicated in the documentation.

Conclusion

Metal tile is a very light, reliable and modern roofing material. Its use in construction significantly reduces the cost of the entire house, as the cost of building load-bearing walls is reduced. However, this the coating requires good thermal and sound insulation. Special tools are required for its installation. Therefore, it is better to entrust the installation to experienced professionals.
