What is electro galvanized steel sheet?

Jul 30, 2024 Leave a message

Electrogalvanized steel sheet is a steel sheet that forms a uniform, dense, and well-bonded zinc coating on the surface of the workpiece through the principle of electrolysis. ‌
This process uses the principle of electrolysis to plate zinc on both sides of the cold-rolled steel sheet to form a metal substrate, thereby enhancing the corrosion resistance of the steel sheet. ‌
Electrogalvanized steel sheet has excellent corrosion resistance and can effectively protect steel parts, especially prevent atmospheric corrosion, and is used for decoration and other purposes. ‌
Depending on different uses, electrogalvanized steel sheet can be phosphated, passivated, oiled, fingerprint-resistant, alloyed and other treatments to meet various specific usage requirements. ‌In addition, electrogalvanized steel sheet can also be colored to form a colored zinc sheet for wall decoration or roof decoration. ‌This steel sheet is widely used in home appliances, computer case shells, door panels and panels due to its excellent corrosion resistance and aesthetics.
