Factory For Cheap Good Quality Roofing Sheet Metal Steel Color Coated - ASTM A653 Plate Galvanized Iron Sheet For Sale 20Gauge 26 Gauge 28Gauge – Win Road Detail:
Galvanized steel sheet is immersed in a molten zinc bath, and a sheet of zinc is adhered to its surface. At present, it is mainly produced by continuous galvanizing process, that is, galvanized steel plate is made by continuously immersing rolled steel plates in a plating tank with molten zinc.
Surface condition: Due to the different treatment methods in the coating process, the surface condition of galvanized sheet is also different, such as ordinary spangle, fine spangle, flat spangle, no spangle and phosphating surface.
Galvanized coating thickness:
Standard value of galvanizing coating: galvanizing amount is a commonly used and effective method to express the thickness of zinc layer of galvanized sheet. The unit of galvanizing amount is g/m2.
Galvanized sheet index (unit: g/m2)

Galvanized coating Z100, Z200, Z275, Z350, Z450, Z600
Performance index: Generally speaking, only the galvanized sheet for structural, tensile and deep drawing has tensile performance requirements. Among them, the galvanized sheet for structural use requires yield point, tensile strength and elongation, etc.; for tensile use, only elongation is required.
