When a person chooses the material for covering the roof or creating a fence on the site, the construction team often recommends using corrugated board. But what is corrugated board and what is it good for? 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 look at what a professional flooring is, what are its pros and cons, the scope. We will also tell you how to choose the right one and how much it costs.
What is corrugated board?
This material is a profiled metal sheet (mainly steel), which was produced by cold rolling and profiled. That is, ribs were artificially created on the sheet to give rigidity. In construction, the value of this material is difficult to overestimate; it can be used for many purposes. But more about that later.
Materials for its manufacture
For the production of material used steel, aluminum, chromium-nickel steel, copper. According to GOST, corrugated board should have a thickness of 0.3-1.2 mm. For different purposes, material of different thicknesses is used. In the manufacture of ribs can be given a different shape: oval, trapezoidal, polygonal, ordinary square, etc.
Also in the manufacturing process, zinc, aluminum and aluminum-zinc coatings are 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 are used such as polyvinyl chloride, polyester, acrylic, polyurethane, etc. Thanks to these polymers, it is possible to preserve the paint layer and protect the color from burning out.
Kinds
The scope of the material determines its type. For example, wall sheeting is used for wall cladding of buildings and creating fences. It is marked with the letter "C". The popular C20 corrugated board can be used for roofing industrial and civil buildings with a batten pitch of 0.4 m or more. In residential construction, this brand is used very widely. C20 decking has a long service life. It retains its aesthetic properties for 10-15 years. Moreover, he has fairly good physical properties. In particular, it perfectly withstands wind loads, which is why it is often used as a building envelope.
The second type is universal. This is HC35 corrugated board, which is intended for roofing and erecting walls, fences. Although most often it is used to create a roof of the roof due to its excellent performance characteristics, this material is perfect for the construction of fences. It can have a polymer or galvanized coating, which effectively protects it from any adverse weather conditions. The thickness of HC35 corrugated board can vary from 0.5 to 0.8 mm, which provides a small weight. At the same time, it is easy to cut, which simplifies the process of installation and dismantling. Well, aesthetic properties are on top: you can give it any color. Partly because of this, it is often used for roofing.
A sheet of H75 corrugated board can have a thickness of 0.4 mm to 1 mm, and it is also produced by cold rolling. Like the previous types, this one is also used for roofing, creating fences or frame structures, as well as for wall cladding. The possibility of galvanizing or applying a polymer layer to H75 corrugated board is included. By the way, it is H-profiles that are load-bearing, therefore it is appropriate to use them to create roofs, fences. They are more rigid and able to withstand severe loads. Most often, for the installation of roofs and walls, the H-153 profile is used.
It is assumed that the brand "C" is intended to create fences and walls. Brand "N" is better suited for the manufacture of visors and awnings, and the universal brand "NS" - for roofing and fences.
It is difficult to determine which decking is better, because it needs to be selected for certain tasks. But you can definitely say that a profile with a large cross section is more durable. Such, for example, is better suited for the installation of building envelopes.
Material advantages
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 distinguish its "non-fragility", so even after falling from a great height nothing will happen to it.
Installation of fencing from corrugated board does not require a foundation, and this is just fine, when compared with brick fences or stone walls. From a design point of view, the material is good, as it is available in many color variations. How the fencing 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 life of the material is 50 years. Although after he will also serve, because it is metal.
It should be noted the cost. The price of corrugated board per m2 favorably distinguishes it from other materials for the roof. Perhaps, only a mesh-netting will cost less when fencing. However, we will talk about the price of corrugated board per m2 a little later.
Minuses
One of the big disadvantages is the so-called drum effect. During rain, the noise level can reach 95 dB (this is in case of heavy rain), therefore, without fail installation of corrugated board involves the use of soundproofing materials (stone or glass wool).
The second minus is a scratch on the anticorrosive layer can lead to early rusting. Therefore, if a deep scratch is found, paint it immediately.
Next is the small thickness of the sheet, due to which installers often suffer during installation or transportation. Cuts and scratches at the corners of the edge are almost always present 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 in this case corresponds. Therefore, it should be handled carefully during installation. It happens that workers from the brigade banally bend the rib, but then align. But the dent is still visible in the end. And this is not unusual, just the technical characteristics of the corrugated board are as follows.
Despite all these shortcomings, the profiled sheet is still one of the most popular building materials in the field of fencing and roofing.
Cost
It is difficult to answer exactly how much a fence from corrugated board costs. Depending on what kind of thickness of corrugated board you will use, the price may be different. For example, if you want to use material 2 meters high and 0.4 mm thick, then the price of such a profile will be 180 rubles per linear meter. In this case, we are talking about an inexpensive polymer profile C8. The same galvanized profile will cost 155 rubles per linear meter.
Usually sellers indicate 2 prices, including the cost per square meter. The price per square meter of C8 polymer corrugated board with a thickness of 0.4 mm is 155 rubles, galvanized - 130 rubles.
But there is more expensive material. C21 decking is more expensive: its price is an average of 175 rubles per square meter. The same galvanized material is slightly cheaper than polymer - 130 rubles.
The indicated prices were taken from Moscow sellers. They can vary greatly depending on the region and the seller himself, therefore, are not final. You may find cheaper material, but be aware that approximately its price per square meter is 130-180 rubles.
Installation cost
The price for the material itself is small, its installation will be more expensive. The prices below are average for Russia, and they may vary depending on the region, the professionalism of the team, etc.
For the installation of one linear meter of the fence, the team takes 500 rubles. This includes marking, drilling holes for poles, stripping and painting these poles, installing in two rows and, of course, installing the corrugated board itself. In this case, the poles will be installed simply in the ground. This is usually sufficient to provide high strength. But also the brigades suggest concreting the pillars, performing their back-up, or even using screw pillars. In this case, the cost of a running meter will increase. For example, the cost of installing corrugated board with concrete concreting will cost an average of 700 rubles per linear meter.
Calculation Example
As you already understood, it is impossible to calculate the default cost, because it will depend on the perimeter and type of corrugated board, as well as other little things: whether there will be concrete pillars, whether there is a need for additional work (for example, dismantling 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 linear meter) + poles. Total can be calculated on 10 thousand rubles (only the material itself).
We can also calculate the cost of work: 40 times 500 (the price for installing a running meter) and we get 20 thousand rubles. We add 10 thousand for the material and get 30 thousand rubles. That's about how you can calculate how much a fence from corrugated board costs, but the team will tell the final price.
With the roof, everything is a little different.
Roof cost
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, steel grade, type of coating, rib height. It is also worthwhile to calculate the cost of a sealant, a layer for sound insulation, wind bars.
The cost of installing roofing from corrugated board
The cost of work is also different, and there is no specific standard. It all depends on the complexity, shape of the roof, the organization of the roofing cake. The roof space is even important.
However, the crews for the arrangement of the roof take about the same, although it is often possible to find extremely cheap offers, but on average the cost of laying a square meter is 150 rubles. It is also worth considering that you will have to pay for laying additional materials, for example, a noise insulation layer, etc. So it is impossible to calculate the cost yourself. It is necessary to call a brigade, to pay for measuring the required work (some do not take money for measuring), the workers calculate and say the final amount. At the same time, they take into account all the difficulties, for example, bypassing the chimney when laying.
Conclusion
Now you have learned what a professional flooring is and what is the way to calculate it. The figures given in the article do not claim to be the ultimate truth, however, the approximate average cost of the material and work with it is as indicated above.
