55%-AL Aluminum Zinc Plated Steel Coil

The production process of aluminum-galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, which is a continuous melt coating process. The coating composition consists of 55% aluminum, 43.4% zinc and 1.6% silicon by weight. 55% aluminum-zinc alloy coated aluminum-zinc steel sheet has superior corrosion resistance compared to galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The 55% aluminum-zinc alloy coated aluminum-zinc steel plate not only has good corrosion resistance, but also has excellent adhesion and flexibility for color-coated products.

The surface of the aluminum-galvanized steel sheet is characterized by a uniquely smooth, flat and gorgeous star, and the base color is silvery-white. The special coating structure gives it excellent corrosion resistance. The normal service life of aluminum-zinc sheet can reach 25A, the heat resistance is very good, and it can be used in a high-temperature environment of 315°C; The adhesion between the coating and the paint film is good, and it has good processing performance, and can be stamped, sheared, welded, etc.; The surface conductivity is very good.
