Electro-galvanized Sheet

Electro-galvanized Sheet refers to a metal material that is treated on the surface of the steel coil by electroplating. It improves the corrosion resistance and oxidation resistance of steel by depositing a layer of zinc on the surface of the steel coil, and is widely used in construction, automobiles, home appliances and other fields.

When producing electro-galvanized sheets, the steel coils are first cleaned, degreased and rusted to ensure a clean surface. The steel plates are then pickled and phosphated to form a phosphate layer to improve the adhesion of the zinc layer. The steel coils are then immersed in an electrolyte containing zinc ions. Through the action of current, the zinc ions are deposited on the surface of the steel coils to form a zinc layer. Finally, the galvanized steel coils are cold rolled and finished and cut into the required size, and packaged for easy transportation and use.

Common grades of electro-galvanized steel include DX51D, DX52D, DX53D, DX54D, SGCC, SECC, SECD, SECE. The grades can be used to indicate the plasticity, weldability, strength, toughness, stamping, corrosion resistance, and paintability of steel.

Differences between hot-dip galvanizing and electrogalvanizing:

Hot-dip galvanizing is to immerse the steel in molten zinc liquid, while electrogalvanizing is to deposit a zinc layer on the surface of the steel by electrolysis. The zinc layer of hot-dip galvanizing is thicker and more corrosion-resistant, but the surface of the zinc layer is not as smooth as that of electrogalvanizing; the zinc layer of electrogalvanizing is thinner and the surface is smoother, but the corrosion resistance is relatively weak.
