Color metal tile is important. But only in terms of design. The only thing to consider when choosing a color is its tone. Dark roofing is heated faster. The main parameter when choosing roofing materials is the life of their operation. The durability of the metal tile depends on:
polymer coating;
metal thickness;
degree of galvanized;
presence of additional additives.

Optimal sheet thickness - 0, 5 mm. Sheets of metal tiles thick 0, 4 mm are permissible to use only for the coating of visors, canopies and small buildings. The material is thick 0, 755 mm has a smaller plate and greater weight compared with sheets of 0.5 mm.

To protect steel from corrosion sheets, metal tiles are covered with zinc. The thickness of the zinc coating ranges from 140 to 275 g per m², the service life of the material directly depends on it.

Another protective layer is a polymer coating. It can be made of polyester, polyurethane, pourala or plastisol. Purel coating and PVF-2 provides a long service life, but at cost exceeds the polyester coating by 30%. The thickness of the polymer coating is from 25 to 200 microns.
5
The warranty period of metal tiles may differ from different manufacturers and depends on the type of coating. When the roof device observe montage rules. In case of violation of these rules, it will be difficult for you to get compensation for poor-quality material. It is important device crate under metal tile.
When buying a material, pay attention to the manufacturer, check the certificates and marking of sheets. It is important to produce all calculations on the consumption of material. If you are mistaken, you will need to buy material, consider the fact that the sheets of metal tile of various manufacturers can not be docked.
