The corrosion resistance of zinc-plated Aluminum is 3 times that of pure zinc-plated steel, with beautiful zinc pattens on the surface, which can be used as exterior construction panels. Aluminum-zinc alloy steel plate with good heat resistance, can withstand more than 300 degrees Celsius, the high temperature. The high thermal reflectivity of the galvanized steel sheet is twice that of the galvanized steel sheet, which is often used as a thermal insulation material. Since the density of 55% al-Zn is less than that of Zn, the area of al-Zn-coated steel sheet is more than 3% larger than that of galvanized steel sheet under the condition of the same weight and the same thickness of gold.
