Product Description Qingdao Ggympeng Merchandising Co.,LtdWelcomeWe are glad to know you are insterested in our products, and hope we have a chance to cooperate each other,thanks!Electro-galvanizing Steel Coil/ SheetProduction ProcessWhat is Electro-galvanizing?Electro-galvanizing is a process in which a layer of zinc is bonded to steel in order to protect against corrosion. Electro-galvanized sheet is manufactured by electroplating a pure zinc coating on one or two sides of carbon steel sheet. This continuous electrolytic coating process can be used to apply the coating onto the surface of the steel sheet with an exceptionally uniform thickness.The Difference Between Electro Galvanizing and Hot Galvanizing1. There is a big difference in the amount of galvanizing between hot-dip galvanized sheet and electro-galvanized sheet. The amount of hot-dip galvanized sheet can not be too small. Generally, minimum is 50-60g/m2 on both sides, and the maximum is 600g/m2. The galvanized layer of the electro galvanized sheet can be very thin, the minimum is 15g/m22. Hot-dip galvanized sheet and electro-galvanized sheet are fundamentally different in the coating structure. 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 crystallizes, zinc flowers are mostly formed, and the coating is uniform and free of pores. The zinc atoms of the electro galvanized sheet layer are only deposited on the surface of the steel strip, and they are attached to the surface of the steel strip by physical action Thank you a lot and I sincerely hope you can pay attention on our products,thanks!
