1. Hot dip galvanized steel plate
Immerse the thin steel plate in the molten zinc bath to make a thin layer of zinc adhere to the surface. At present, it is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the molten zinc plating bath to make a galvanized steel plate. This kind of steel plate is also made by hot dipping method, but it is heated to about 500°C immediately after leaving the trough to make it form an alloy film of zinc and iron. This galvanized sheet has good paint adhesion and weldability.
2. Alloyed galvanized steel plate
This kind of steel plate is made by hot dipping method and then alloyed. It has excellent coating adhesion and is widely used in applications requiring high processing performance.
3. Electro-galvanized steel sheet
The galvanized steel sheet manufactured by the electroplating method has good workability. However, the coating is thinner than hot dip galvanized sheet, and the corrosion resistance is not as good as hot dip galvanized sheet. It is more suitable for indoor or light corrosion environments.
4. Single-sided and double-sided galvanized steel sheets
Single-sided galvanized steel sheet refers to products that are galvanized on only one side. In welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheet. To overcome the shortcomings of uncoated zinc on one side, there is also a galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided galvanized sheet.
5. Alloy and composite galvanized steel plate
It is a steel plate made of zinc and other metals such as aluminum, lead, zinc, etc. through alloy or even composite plating. This steel plate has both excellent anti-rust performance and good coating performance, and is suitable for more demanding use environments.
