What is corrugated board: types, description, technical characteristics, purpose

When a person chooses the material to cover the roof or create a fence on the site, the construction team often recommends using profiled sheeting. But what is profnastil and what is it good? Due to its technical characteristics and price, it has become one of the most popular and sought after building materials on the market. Let's analyze what is profnastil, what are its pros and cons, scope. Also tell you how to choose the right amount and how much it costs.

What is corrugated board?

This material is a profiled metal sheet (mainly steel), which was produced by the cold rolling method and profiled. That is, the ribs were artificially created with the aim of stiffening. In construction, the value of this material is difficult to overestimate, it can be used for many purposes. But about this - a little later.

Materials for its manufacture

To produce the material, steel, aluminum, chromium-nickel steel, and copper are used. According to GOST, profiled sheeting should have a thickness of 0.3-1.2 mm. For different purposes, material of different thickness is used. In the manufacture of ribs can give a different shape: oval, trapezoidal, polygonal, ordinary square, etc.

Also in the manufacturing process, zinc, aluminum and aluminium zinc coating is used (usually 100-275 grams per square meter of layer), which gives anticorrosive properties to the material. And to increase the strength and wear resistance, different polymers such as polyvinylchloride, polyester, acrylic, polyurethane, etc., are used. Thanks to these polymers, it is possible to preserve the paint layer and prevent color from burning out.

Kinds

The scope of the material determines its appearance. For example, corrugated board for walls is used for cladding the walls of buildings and creating a fence. It is marked with the letter "C". The popular corrugated board C20 can be used for the roofing of industrial and civil buildings with a bracing step of 0.4 m. In residential construction this brand is used very widely. Profiled sheeting C20 has a long service life. It retains its aesthetic properties for 10-15 years. At the same time, he has good physical properties. In particular, it perfectly withstands wind loads, because of what it is often used as a fencing structure.

The second type is universal. This is a corrugated board NS35, which is intended for roofing of the roof and erection of walls, fences. Although most often it is used to create a roofing roof because of its excellent performance characteristics, this material is perfect for erecting enclosures. It can have a polymer or galvanized coating, which effectively protects it from any unfavorable weather conditions. Thickness of corrugated board НС35 can vary from 0,5 to 0,8 mm that provides small weight. At the same time, it is easily cut, which simplifies the installation and dismantling process. Well, aesthetic properties at altitude: he can give any color. Partly because of this, it is often used for roofing.

The sheet of corrugated sheet H75 can have a thickness from 0.4 mm to 1 mm, and it is also produced by cold rolling. Like the previous species, this one is also used for roofing, fencing or frame construction, as well as for wall cladding. The possibility of galvanizing or applying a polymer layer to the profiled sheeting H75 is attached. By the way, it is the H-profiles that are carriers, so they are appropriate to use for creating a roof, fences. They are more rigid and capable of withstanding serious loads. The most common for the construction of the roof and walls is the profile H-153.

It is assumed that the mark "C" is intended for the creation of fences and walls. Mark "H" is better for making canopies and canopies, and the universal brand "NS" - for roofing and fences.

It is difficult to determine which profile is better, because it needs to be selected for certain tasks. But you can definitely say that the profile with a larger cross section is more durable. Such, for example, is better suited for the construction of enclosing structures.

Advantages of the material

One of the first advantages of the material is its light weight and ease of installation. If you compare it with natural tiles or, for example, with slate, you can even highlight its "non-fragility", so even after a fall from a great height nothing will happen to it.

The installation of a fence made of corrugated board does not require the installation of a foundation, and this is just fine if compared with brick fences or stone walls. From the design point of view, the material is good, as it is available in many color variations. How does the fence of the house, made of corrugated board, can be seen in the photo below.

The next advantage is protection against corrosion (due to coating), mechanical damage, ultraviolet radiation, temperature changes. The service life of the material is 50 years. Although after that he will also serve, because it's metal.

It is impossible not to note the cost. The price of corrugated board per m2 favorably distinguishes it from other materials for roofing. Perhaps, only net-rabitsa will cost less when installing fencing. However, the price of corrugated board per m2 we will talk a little later.

Minuses

One of the big disadvantages is the so-called drum effect. During the rain, the noise level can reach 95 dB (this is for a heavy rainfall), therefore, mandatory installation of the corrugated board involves the use of soundproof materials (stone or glass wool).

The second negative - a scratch on the anti-corrosion layer can lead to an early rust. Therefore, if you find a deep scratch, you should immediately paint it.

Further - a small thickness of the sheet, because of which the installers often suffer during installation or transportation. Cuts and scratches on the corners of the edge are almost always available during installation.

Roofing corrugated board with a sheet thickness of up to 0.55 mm is easily deformed. This is the last disadvantage of corrugated board. GOST at the same time. Therefore, it is necessary to handle it carefully during installation. It happens that the workers from the team cornyly bend the rib, but then they even out. But the dent is still visible in the end. And in this there is nothing unusual, just the technical characteristics of the corrugated board are as follows.

Despite all these drawbacks, the profiled sheet is still one of the most popular building materials in the field of fencing and roofing.

Cost

It is difficult to accurately answer, how much is a fence of corrugated board. Depending on exactly what thickness of corrugated board you will use, the price can be different. For example, if you want to use a material 2 meters high and 0.4 mm thick, the price for such a profile will be 180 rubles per running meter. In this case, we are talking about an inexpensive polymer profiled C8. The same galvanized profile will cost 155 rubles per running meter.

Typically, sellers indicate 2 prices, including the cost per square meter. The price per square meter of polymeric corrugated board C8 0,4 mm thick is 155 rubles, galvanized - 130 rubles.

But there is also more expensive material. Profiled sheeting C21 is more expensive: its price is on average 175 rubles per square meter. The same galvanized material is slightly cheaper than polymer - 130 rubles.

These prices were taken from Moscow sellers. They can vary greatly depending on the region and directly the seller, therefore, are not final. Perhaps you will find cheaper material, but know that approximately its price per square meter is 130-180 rubles.

Cost of installation

The price for the material itself is small, its installation will be more expensive. The prices listed below are average for Russia, and they can vary depending on the region, brigade professionalism, etc.

For the installation of one running meter of the fence, the brigade takes 500 rubles. This includes marking, drilling holes for poles, stripping and painting these pillars, installing in two rows and, of course, installing the corrugated board itself. In this case, the poles will be installed simply in the ground. Usually this is sufficient to ensure high strength. But also the brigades offer to concrete the pillars, perform their backstaying or even use screw posts. In this case, the cost per meter will grow. For example, the cost of installing a corrugated board with concreting the pillars will cost an average of 700 rubles per running meter.

Example calculation

As you have already understood, it is impossible to calculate the default cost, because it will depend on the perimeter and the type of corrugated board, as well as other minor things: whether there will be concreting of poles, whether there is a need for additional work (for example, dismantling of the old fence), etc.

But as an example, we give the simplest calculation.

Let's say you need to make a fence around the perimeter. You measured all sides and got the required length of 40 meters (10 meters on each side). This means that for the material itself you will have to pay 7200 rubles (180 rubles per running meter) + poles. Total you can count on 10 thousand rubles (only the material itself).

We can now calculate the cost of the work: 40 multiplied by 500 (the price for installing the running meter) and we get 20 thousand rubles. Add 10 thousand for the material and get 30 thousand rubles. That's how you can approximately calculate how much a fence of corrugated board is worth, but the final price will be told by the team.

With the roof everything is a little different.

Cost of roofing

The price for the material will be approximately the same: about 160-200 rubles per square meter. So much is the cheapest galvanized corrugated board. As you can see, the cost of the material is the same. Moreover, the material itself is the same, it can be used for both the roof and the fence device. But the final price will depend on the thickness of the sheet, the grade of steel, the type of coating, the height of the rib. Also, in addition, it is necessary to calculate the cost of the sealant, the layer for noise insulation, the windshields.

The cost of installing the roof of the corrugated board

The cost of the work is also different, and there is no definite standard. Everything depends on the complexity, the shape of the roof, the organization of the roof cake. Has even the significance of the under-roof space.

However, brigades for the arrangement of the roof take about the same, although you can often find extremely cheap offers, but on average the price of laying a square meter is 150 rubles. Also it is worth considering that you have to pay for laying additional materials, for example, a layer of noise insulation, etc. So it is impossible to calculate the cost yourself. It is necessary to call a brigade, pay for the measurement of the required work (some do not take money for measuring), workers count and say the final amount. In this case, they take into account all the difficulties, for example, bypassing the chimney during laying.

Conclusion

Now you have learned what is profiled and what is the way to count it. The figures in the article do not pretend to be true in the last instance, however, the approximate average cost of the material and works with it is as described above.
