The aluminum-zinc-plated steel alloy coating is composed of about 55% aluminum, about 43.5% zinc, and about 1.5% silicon. Compared with traditional galvanized products, it has more excellent corrosion resistance, heat resistance, heat reflectivity and other characteristics. The zinc flower(spangle) on the surface of the aluminum-plated zinc plate is small and uniform, with bright colors and high surface hardness. It can be coated with fingerprint-resistant semi-permeable membranes of various colors, and is widely used in household appliances, construction, structure, electrical and other industries.
