Post Overview

The material of galvanized sheet is steel plate coated with a layer of zinc on the surface, which provides a certain degree of corrosion resistance.

Galvanized sheets are mainly divided into the following types:

Hot-dip galvanized steel sheet

Alloyed galvanized steel sheet

Electro-galvanized steel sheet

Single-sided or differentially coated galvanized steel sheet

Alloy-composite galvanized steel sheet

Hot-dip galvanized steel sheet: The thin sheet is immersed in a molten zinc bath to coat it with a thin layer of zinc. It is primarily produced using the continuous galvanizing method, where the entire coil of steel plate is continuously immersed in the molten zinc bath.

Hot-dip galvanized non-alloy steel sheets can be used for general purposes, deep drawing, or seaming. The higher the zinc content in the coating, the better the corrosion resistance, while lower zinc content improves mechanical properties.

Hot-dip galvanized alloy strips can be used for structural purposes, stamping, and cold forming. This material has good weldability and paint adhesion but is prone to peeling during processing.

Electro-galvanized steel sheet: Zinc is applied to the steel plate through an electroplating process, but the resulting zinc layer is relatively thin, offering weaker corrosion resistance.

Additional Information: Stainless steel achieves corrosion resistance by altering the steel's composition with trace elements. Electro-galvanized sheets sacrifice zinc to coat conventional steel plates through electroplating. Temperatures of 200°C and 300°C have no significant effect on the metal, but subtle changes may occur over a long period depending on the surrounding environment.
