Galvanized sheet and stainless steel sheet are two common metal materials, each with unique characteristics and application areas.

Corrosion resistance: Stainless steel generally has higher corrosion resistance than galvanized sheet. Stainless steel contains at least 10.5% chromium, which enables it to form a dense oxide film on the surface, thereby improving its corrosion resistance. In contrast, galvanized sheet relies on the sacrificial protection of its surface zinc layer to prevent corrosion. Once the zinc layer is damaged, the steel below will be exposed to the corrosive environment 100.

Processing technology: Galvanized sheet is made by plating a layer of zinc on the surface of steel. This process can be electroplating (cold galvanizing) or hot dipping (hot galvanizing). Stainless steel achieves its rust-free characteristics by adding metal elements such as chromium and nickel to steel and changing its internal structure 102.
