Profiled sheeting C21: technical characteristics and features

Profiled sheeting C21, whose technical characteristics will be described below, is one of the most common varieties of this material.

Scope of use

This type of corrugated board is used for the installation of roofing systems for buildings of any purpose. This material can be mounted on the surface with any gradient. It is also actively used to create fences, as well as shield structures, this material can lie in wall systems that have or lack a thermal insulation layer. Profile flooring looks great, which is why it is used for facing the walls in the process of reconstruction works. This material is used when creating sandwich panels.

Advantages of profile flooring C21

Profiled sheeting C21, whose technical characteristics attract more and more consumers, has a lot of advantages. So, the material combines an impressive height and thickness of the wave, which gives it the quality of durability and strength. However, the sheets do not have an impressive weight, which ensures ease of installation work. Cloths are very economical, but are not so expensive as analogs. You can buy a sheet for about 300 rubles. But the cost, of course, varies depending on some characteristics of the material, among which, for example, thickness.

Profiled sheeting C21, whose technical characteristics allow it to be used in many areas of construction, has a wide range of colors. For sale are galvanized and paint-covered sheets. Choose profiled flooring C21 also for a long period of its suitability, in addition, the linens are very resistant to corrosion processes. The latter quality is due to the fact that there is a polymer coating on the surface . Serving material can for three decades and even more, the duration of this period will be affected by external conditions.

Characteristics

Profiled sheeting C21, the technical characteristics of which differ from the parameters of other materials, is able to undergo external influences, for example, in the form of wind, high humidity and imposing loads. According to available standards, the thickness of the canvas should be 0.4-0.8 mm, while the minimum length is 0.5 m and the maximum length is 15 m. The width of the sheet is limited by two factors, the first of which is common (1100 mm) , And the second - working (1000 mm).

The name contains the alphanumeric designation C21, which indicates the wave height - 21 mm, but the "C" is a material that belongs to the category of thin products.

Profile floor weight

Profiled sheeting C21 1000 can have a different weight, depending on the thickness of the steel used in its production. So, if the last figure is 0.4 mm, then the weight of 1 running meter will be equivalent to 4.45 kg. But with a steel thickness of 0.55 mm, the weight of the running meter will be 5.91 kg. The thickness, limited to 0.8 mm, will give the weight of the running meter at 8.37 kg.

Galvanized profile flooring

Corrugated board Z21 galvanized is manufactured using cold-rolled steel, a polymer coating is applied to its surface during production , the thickness of which is 0.5-0.7 mm. This material can have a coating based on PVDF, polyester or PVC. If you need to cover the roof, you should choose galvanized material, which has a more impressive wave height. Among the main characteristics of the profiled sheeting can be identified:

• Significant strength;
• High wave height;
• rigidity;
• Resistance to high temperature range.

Qualitative characteristics

When choosing profiled flooring, it is important to remember that you should not rely on the supplier's honesty. This indicates that the quality should be checked independently. So, on the surface though and there can be absolutely small attritions and dents, but their diameter should not appear more than 5 mm. Thickness is also an important indicator, which is worth checking out. By standards it is possible to purchase sheets in which there are deviations in width not exceeding 1 mm, as to length, the maximum deviation limit should not be more than 10 mm, in thickness - no more than 0.5 mm. If there are cracks on the surface, then sheets with such errors can not be used in construction, since such material is considered to be a marriage.

It is important in the design of the roof to determine the weight of corrugated board C21 can be used for work. This factor is influenced by many factors, among them we can distinguish the bearing capacity of the foundation and walls, wind and snow loads and much more. When choosing a material, it is worth paying attention to these parameters, only then it will be possible to get a house, the roof of which will last for a long time. After all, if you choose a heavy roofing material that will not be able to withstand the foundation, then eventually the house will begin to settle, which will require a serious reconstruction of the basement.
