Dx51d Z60 Z150 Z275 Roofing Material Gi Galvanized Steel Corrugated Roofing Sheet Steel Manufacturing

Dx51d Z60 Z150 Z275 Roofing Material Gi Galvanized Steel Corrugated Roofing Sheet Steel Manufacturing Corrugated Roofing Sheet Steel 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, and it is a continuous molten coating process. The galvanized steel sheet with 55% aluminum-zinc alloy coating has better corrosion resistance than 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 products have excellent adhesion and flexibility.DX52D+AZ/DX51D+AZGalvalume/galv......
