Hot-dip galvanized steel sheet. A thin steel plate is immersed in a molten zinc bath, resulting in a thin layer of zinc adhering to its surface. Currently, the main production method is continuous galvanizing, which involves immersing rolled steel plates continuously in a zinc-coated bath to form galvanized steel sheets.

Alloyed galvanized steel sheet. This type of sheet is also manufactured using the hot-dip process, but immediately after dipping, it is heated to approximately 500°C to form an alloy film of zinc and iron. The galvanized sheet exhibits good adhesion to paint and welding properties.

Electro galvanized steel sheetThis galvanized steel sheet produced by electroplating offers good workability. However, the coating is thinner and less corrosion-resistant than that of hot-dip galvanized sheets.

Single-sided galvanized steel sheets and double-sided differential galvanized steel sheets. Single-sided galvanized steel sheets refer to products that are zinc-coated on only one side. They offer better adaptability in welding, painting, rust prevention, and processing compared to double-sided galvanized sheets. To overcome the drawback of uncoated zinc on one side, there is also a type of galvanized sheet with a thin zinc coating on the other side, known as double-sided differential galvanized steel sheets.Alloyed and composite galvanized steel sheets. Made from zinc and other metals such as aluminum, lead, and zinc, these sheets are alloyed and then coated. They offer both rust-proof properties and excellent painting performance.
