Basically, as a roofing, steel, copper nickel – titanium and aluminum sheets are used. Steel coating is made from a sheet of steel, which is covered with a layer of zinc or alloy of zinc and aluminum. Steel sheets are covered with these protective suspensions at the stage of manufacturing sheets on an industrial scale. Before heat, how to cover steel with a zinc coating, the base is passing and necessarily primed. After that, laco is applied to the front side of the sheet – colorful coatings, which mainly performs a decorative and visually polymer function.

A thin layer of varnish is applied to the sheet, this is done so that steam or condensate does not damage the sheet from below. A leaf of titanium -zinc alloy does not require additional manipulations with a protective coating, since the material itself is able to resist corrosion. However, it cannot be argued that a leaf of titanium – zinc alloy consists only of these two components, often an admixture of aluminum is also included in the composition of such a sheet. This is done in order to slightly increase the plasticity of the sheet. Titan gives strength, and an admixture of zinc – a rebuff of corrosion. After manufacturing, the sheet panifies which gives it a natural color and an excellent shade.
