Such a roof is made by steel galvanized profiled sheets, which are coated with polymers, and after passing the stamping with a cold method, it appears a characteristic figure, it resembles a tile of natural material. Sheet is made of small thickness. Manufacturers make metal tile with an anti-corrosion coating, it is treated with a thin layer of zinc, after which a layer of protection from different polymer compounds is applied to it. Before repair do not forget to buy new windows in Nizhny Novgorod there they are inexpensive.
It is because of the coverage of sheets of tiles from the metal, it acquires its characteristic properties. The polymer coating creates a stable reaction to the aggressiveness of the environment, it easily makes various mechanical loads, such as snow cover, it does not respond at all to ultraviolet radiation and makes a sharp drop of low and high temperatures. In addition to protection, the coating of multi-colored polymers give sheets of metal roofing unique unique appearance. Covered tile polymers only in factory conditions, which are engaged in the production of galvanized steel rolls. To protect all products from applying scratches and damage to the upper layer, they are treated with a special lacquered coating.
