Hot Dipped Cold Rolled Galvanized Steel Coil Z125 With Gauge 22 24 28 30
Hot-dip galvanized sheet and electro-galvanized sheet are fundamentally different in the structure of the coating. There is a slightly brittle compound layer between the pure zinc coating of the hot-dip galvanized sheet and the steel strip substrate. When the pure zinc coating is crystallized, most of the zinc flowers are formed, and the coating is uniform and free of pores. The zinc atoms of the electro-galvanized layer are only deposited and precipitated on the surface of the steel strip, and are attached to the surface of the steel strip by physical action. Therefore, hot-dip galvanized sheet is more corrosion-resistant than electro-galvanized sheet.
