For those who are going to do construction work, it will be useful to find out everything about the C15 professional sheet, about its dimensions and other technical characteristics. The article gives recommendations on the selection of self-tapping screws for a profiled sheet. Described corrugated sheets for wood and their other varieties.

What is it and how is professional flooring done?

The most important thing in describing the C15 profiled sheet is that it is made of rolled steel. The surface of such a material, after special technological manipulations, gets the shape of waves or is corrugated . The main task of processing is to increase the rigidity in the longitudinal plane and increase the bearing capacity. Engineers were able to work out the technology in such a way that it significantly increases the resistance of the material to loads both in statics and in dynamics. The original metal thickness can range from 0.45 to 1.2 mm.

The letter C in the marking indicates that this is strictly a wall material . It is not very desirable to use it for roofing work, and only for insignificant structures. Modern corrugated board is distinguished by decent operational parameters and costs relatively little. The metal is usually rolled in a cold way.

As a blank, not only simple galvanized steel can be taken, but also metal with a polymer coating.

Simultaneous profiling implies that all corrugations are rolled at the same time, the starting point is the first stand of the rolling equipment. This approach can significantly reduce processing time. In addition, increased uniformity is ensured. The appearance of defective edges is almost impossible. A typical production line, in addition to the decoiler, necessarily includes:

• cold rolling mill;
• receiving block;
• hydraulic guillotine shears;
• an automatic unit that maintains a clear and well-coordinated work.

The steel passed through the unwinder is fed to the forming machine. There, its surface is profiled. Special scissors allow you to cut metal according to the design dimensions. Different rollers are used to influence the profile. The product removed from the receiving device is marked by accessory.

The cantilever decoiler actually has a double subordination, so to speak . Of course, it is controlled by a general automatic system. But it also includes internal automation, which is responsible for the synchronization of the arrival of steel strips and the rate of rolling processing. The number of stands in rolling mills is determined by the complexity of the created scheme. Molding machines are divided according to the type of drive into pneumatic and hydraulic machines; the second type is more powerful and can produce sheets of theoretically unlimited length.

Specifications

S-15 professional flooring began to enter the market relatively recently. Engineers note that it has occupied a niche between the traditional low-profile wall sheet C8 and hybrid C21 (suitable for roofs of private homes) . In terms of rigidity, it is also in an intermediate position, which is very important for many customers. The dimensions of the C15 profiled sheet according to GOST may vary. In one case, it is the "long-arm" C15-800, the total width of which is 940 mm. But if the index 1000 is assigned to the sheet, then it already reaches 1018 mm, and instead of "shoulders" there will be a cut wave at the edge.

The problem is that in practical use, the sizes according to the state standard did not justify themselves. Therefore, most of the technical conditions imply a total width of 1175 mm, of which 1150 falls on the working area. In the descriptions and catalogs it is said that this is a profile with an index. This designation avoids confusion. But the difference between products according to GOST and according to TU is not limited to that, it also applies to:

• pitch of profiles;
• the size of the narrow profiles;
• the size of the shelves;
• degrees of bevels;
• bearing characteristics;
• mechanical rigidity;
• mass of a single product and other parameters.

Species overview

A simple corrugated sheet is boring and monotonous. Many tens of kilometers of dull walls and no less dull fences from it no longer cause anything but irritation . But the designers have learned to solve this problem by imitating the appearance of other materials. In the overwhelming majority of cases, they try to buy profiled sheets trimmed with wood. Such a coating looks natural and does not bother for a long time.

The technology has already been worked out, allowing, along with the profile of the wood, to reproduce its texture as well. The special coating not only makes the material more beautiful, it also increases its resistance to adverse influences. This technique was first tested by a large South Korean manufacturer in the early 1990s. Most often, the necessary protection is provided by aluzinc. Also, the profiled sheet can simulate the surface:

• timber;
• bricks;
• natural stone.

The cheapest option for protection is classic galvanizing . But its characteristics are enough just that only for minimal resistance to adverse factors. Sometimes they resort to metal passivation. The front polymer coating plays an important role.

Only high-quality application of it allows you to avoid fading and contact of the base with aggressive environmental factors.

Applications

C15 professional flooring is in demand both in the city and in the countryside to the same extent. It is readily purchased by both individuals and organizations. Such a sheet becomes an excellent basis for a fence. An important advantage lies not only in its beautiful appearance, but also in the fact that the installation is not particularly difficult . The strength is also quite enough for the arrangement of the barrier.

However - "not a single fence", of course. C15 professional sheet is in demand for large-scale construction. It allows the construction of hangars and warehouses of a large area. In a similar way, pavilions, stalls and similar objects are built in a short time. Sheets can be assembled even alone.

Alternative applications:

• partitions;
• dropped ceilings;
• visors;
• awnings.

Installation tips

The most important thing, perhaps, is to choose self-tapping screws of a suitable section. It is better if they are immediately with plugs, which exclude the ingress of moisture under the hardware and the further development of corrosion. It must be understood that there is a difference between several different situations:

• joining an already finished wall;
• assembly to a prefabricated wall;
• the performance of the function of the wall itself by the corrugated board.

In the first option, it is assumed that the structure was insulated already before the installation of the corrugated board. Getting started - installing brackets. They are fixed not only on self-tapping screws, but also sometimes on dowels (depending on the supporting material). Then, using the "fungi", a slab insulation is installed. Instead of "fungi", you can use simple self-tapping screws, but they will have to be supplemented with wide washers. Then, on top of the polyethylene, a frame is formed under the profiled sheets themselves.

In the second method, usually used for frame construction, it is necessary to attach the sheets to the frame using self-tapping screws . They are equipped with a lining under the cap. The foundation must be pre-waterproofed, and only then a profile is installed on it, attached with universal self-tapping screws. An internal vapor barrier is also needed. Only on top of it is a heater placed, additionally covered with polyethylene.

The third scheme is the easiest to work with. Then the installation of the wall is almost no different from the arrangement of the fence. You need to fasten the sheets in the lower parts of the waves. The joining points are riveted with a pitch of 300 mm.

This process has no more subtleties.
