The galvalume steel coil is based on the aluminum-zinc alloy structure which is composed of 55% aluminum, 43.4% zinc and 1.6% silicium, and formed by solidification under the high temperature of 600°C. It is actually the alloy coated steel plate with the structure of compact four-element crystal formed via aluminum, ferrum, silicium and zinc. Compared with the hot dipped galvanized steel plate, the product shows more excellent performance in corrosion resistance, heat resistance and heat reflectivity. Therefore, the galvalume steel coil has been largely applied into many fields.
