C21 corrugated board, the technical characteristics of which will be described below, is one of the most common varieties of this material.
Area of use
The mentioned variety of corrugated board is used in the installation of roofing systems of buildings for any purpose. This material can be mounted on a surface with any bias. It is also actively used to create fences, as well as panel structures, this material can lie in wall systems that have or are devoid of an insulating layer. Profile flooring looks great, which is why it is used for wall cladding in the process of reconstruction. This material is used to create sandwich panels.
Pros of C21 profile flooring
C21 professional flooring, the technical characteristics of which are attracting an increasing number of 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. Cloths are very economical, but are not as expensive as their counterparts. You can buy a sheet at a price of approximately 300 rubles. But the cost, of course, varies depending on some characteristics of the material, among which, for example, thickness.
C21 decking, the technical characteristics of which allow it to be used in many areas of construction, has an extensive color gamut. For sale are galvanized and painted sheets. The profiled flooring C21 is also chosen for its long service life, in addition, the canvases are very resistant to corrosion processes. The latter quality is due to the fact that there is a polymer coating on the surface . The material can last for three decades or more, the external conditions will affect the duration of this period.
Specifications
C21 decking, 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 impressive loads. According to existing standards, the thickness of the web should be 0.4-0.8 mm, while its minimum length is 0.5 m and the maximum is 15 m. The width of the sheet is limited by two indicators, the first of which is general (1100 mm) and the second to the worker (1000 mm).
The name contains an alphanumeric designation C21, which indicates a wave height of 21 mm, but “C” is a material that belongs to the category of thin products.
Profile flooring weight
C21 1000 corrugated board can have a different mass, depending on the thickness of the steel used in its production. So, if the last indicator 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 a running meter will be 5.91 kg. A thickness limited to 0.8 mm will give a running meter weight of 8.37 kg.
Galvanized profile flooring
Galvanized steel sheet C21 is made using cold rolled steel, a polymer coating is applied to its surface during the production process , the thickness of which is 0.5-0.7 mm. This material may be coated with PVDF, polyester or PVC. If you need to close the roof, then you should choose a galvanized material, which has a more impressive wave height. Among the main characteristics of the described professional flooring, one can distinguish:
- significant strength;
- high wave height;
- rigidity;
- resistance to a high temperature range.
Quality characteristics
When choosing a profiled flooring, it is important to remember that you should not rely on the honesty of the supplier. This indicates that quality should be checked independently. So, although there may be very small scuffs and dents on the surface, their diameter should not be more than 5 mm. Thickness is also an important indicator that is worth checking. According to the standards, it is possible to purchase sheets in which there are deviations in width not exceeding 1 mm, with regard to length, the maximum deviation limit should not be more than 10 mm, in thickness - not more than 0.5 mm. If there are cracks on the surface, then sheets with such errors cannot be used in construction, since such a material is considered defective.
When designing a roof, it is important to determine how much weight C21 corrugated board can be used during work. This factor is influenced by many factors, among them the bearing capacity of the foundation and walls, wind and snow load, and much more can be distinguished. When choosing a material, it is worth paying attention to these parameters, only then you can get a house whose roof will last a long time. After all, if you choose heavy roofing material that will not be able to withstand the foundation, then over time the house will begin to settle, which will require serious reconstruction of the base.
