Galvanized steel panel 103

The coating composition is composed of 55% aluminum, 43.4% zinc and 1.6% silicon in weight ratio. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, which is a continuous molten coating process. The 55% aluminum-zinc alloy-coated galvanized steel sheet has better corrosion resistance than the 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 sheet not only has good corrosion resistance, but also the color-coated product has excellent adhesion and flexibility.

       Single-sided zinc layer is a hot-dip galvanized sheet with a certain thickness of zinc layer on one side and no galvanized on the other side. The production methods of single-sided hot-dip galvanized sheet include zinc thinning method, direct method, indirect method and double-layer separation method. Single-sided hot-dip galvanized sheet is mainly used in automobile manufacturing. The surface with zinc layer is anti-corrosion, and the surface without zinc layer is good for spot welding. As alloyed sheets (zinc-iron alloys) have good weldability, single-sided galvanized sheets have been gradually eliminated. 　　 

        Galvanized steel sheet is to avoid corrosion of the surface of the thick steel sheet and increase its service life. The surface of the thick steel sheet is coated with a layer of metal material zinc. This kind of galvanized cold rolled steel sheet is called galvanized sheet
