Hot-dip (aluminum) zinc sheets is an alloy-coated steel sheets with (aluminum) zinc alloy covering on the surface of the sheet, and aluminum-iron-zinc-silicon coating being dense quaternary crystal. The coating is of good corrosion resistance, heat resistance, heat reflectivity, formability, coating ability and economic performance. The uniform solid dendritic Al-Zn alloy crystal pattern on the surface of the coating presents a good ornamental effect. Galvanized (aluminum) zinc steel sheets are alloy-coated steel sheets widely used in many fields such as building materials, home appliances, automobiles, environment, machinery, electrical appliances, and ships.
