Some are used for electric utilities.Military facilities, civilian facilities and so on.Mainly to prevent the corrosion of steel.Prolong the service life of galvanized products,It is mainly used for outdoor weather resistance of iron and steel materials. Compared with cold plating (electroplating), the coating is thicker and can increase the weather resistance.Applications such as power system tower, traffic fence, trough and so on.
The galvalume coating is an alloy consisting of approximately 55% aluminum, 43.4% zinc and 1.5% silicon by weight, which is applied to steel by the continuous hot dip process. Galvalume steel sheet offers the best qualities of aluminum coated (aluminized) and zinc coated steel sheet (galvanized). The aluminum/zinc coating has barrier corrosion resistance and heat resistance similar to aluminum coated steel. It also has good bare edge galvanic protection and forming qualities similar to continuously annealed commercial quality galvanized. The appearance of Galvalume coating is quite distinctive. Its smooth, flat and fine spangle and a silvery metallic appearance make it attractive in unpainted applications.
