Product quality directly depends on the selected material. Such a rule is applicable for a profiled sheet. Today, corrugated board is made of steel not lower than XII class C 0.6-1.6 millimeter thickness, while the rental sheet is formed in rolls up to 1740 millimeters wide. If you are building a mansion, then it is also worth installing the security post at the entrance to the territory of the house.
But not the entire profiled sheet is made of such high quality steel. There are varieties, in particular, the one that is made from the group (general purpose). Therefore, they do not have such high mechanical properties. Therefore, it is impossible to use them as supporting structures. They were created for use in structures with a small bearing force. And this is nothing more than the installation of corrugated board for the roof and the organization of wall fences of auxiliary purposes.
As for anti -corrosion protection, the quality of galvanizing directly depends on the thickness of the applied layer of zinc. Usually corrugated board is protected by a hot manner of galvanizing.
As a result, the profiled flooring in the context takes the shape of a multilayer pie. So enhanced anti -corrosion protection allows you to increase the resistance of the sheet from 1.9 to 2.7 times compared to the general indicators of the protection of each layer separately.
