In recent years, one of the popular materials for roofing has been profiled metal sheets, which are made of cold-rolled steel sheets with any protective coating applied to the outer surface. In the section, such sheets have a trapezoidal profile that gives the product strength and transverse rigidity, and galvanizing, polymer compounds or combined coating are used as a protective layer.
The demand for profiled sheets for the construction of the roof is due to a number of their advantages over other roofing materials. First of all, these products are not very large, so such a roof will not require the installation of powerful rafters. These sheets can be used for construction facilities for various purposes, they are easy to lay on a roof of different shapes, including complex and curvilinear, since the sheets are simply cut and bended. Laying profiled sheets can be done at any time of the year without the use of special equipment or tools, that is, roofing can be done on their own. Due to the exact manufacture of the profile, the sheets allow to ensure high tightness, and the roofing material is the durability of the roof.
