Product description:
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.
Product description:
Hot-dip Alu-zinc alloy coated steel (GL) is a kind of highly corrosion-resistant material. It is formed with cold-rolled steel and applied with a coating consisting of 55% aluminum and zinc.
Application:
They are widely used in construction, automobiles, home appliances and other industrial products. In the construction industry, they are used for light-weight steel keels, building slabs, corrugated boards and rolling doors in various industrial and civil buildings. In the automobile industry, they are used for the shells, interior panels and floor of the automobile body. In home appliances and light industry, they are used for the shells and bottom panels of various household appliances.
