Astm A792 Galvalume Steel Coil
A Galvalume steel coil refers to a continuous length of steel sheet that has been coated with the 55% aluminum-zinc alloy. The coil is produced through a hot-dipping process where the steel sheet is passed through a molten bath of aluminum and zinc.
The ASTM A792 specification covers various dimensions and tolerances for Galvalume steel coils, including the chemical composition of the coating, the coating weight, thickness, and width of the coil. It also covers the mechanical properties of the coated sheet, including the tensile strength, yield strength, and elongation.
Galvalume steel coils are commonly used in the construction industry for roofing, siding, and wall panels due to their excellent corrosion resistance, durability, and attractive appearance.
