Hot-dip galvanized plate is galvanized on the surface of thin Steel Plate and steel strip by continuous hot-dip method, which can prevent corrosion and rust on the surface of the thin steel plate and steel strip.
Galvanized steel sheets and steel strips are widely used in machinery, light industry, construction, transportation, chemical, post, and telecommunications industries.
Hot-dip galvanized Steel Sheet is mainly used in the construction industry, vehicle and ship manufacturing industry, container manufacturing industry, as well as electromechanical industry and household appliance industry, as equipment shell, support frame or light bracket, etc.
Hot-dip galvanized steel pipes are mainly used in the petrochemical equipment industry, water conservancy engineering and mining industry, construction industry, etc. as metal structure or transportation pipeline.
Hot-dip galvanized steel wire is mainly used in dry metallurgy, petroleum, machinery, chemical industry, electric power, aviation, and other industries.
Hot-dip galvanized steel structure and section steel are mainly used in industries such as electric power, communications, and transportation.
The main characteristics of hot-dip galvanized steel (SGCC): 1. Corrosion resistance; 2. Paintability; 3. Formability; 4. Spot weldability. Usage: Very wide range, small household appliances, good appearance, but more expensive than SECC.
Galvanized steel has good resistance to atmospheric corrosion. Since the potential of zinc is lower than that of iron, the zinc layer is positive for the steel substrate and iron is negative.
In the electrolytic solution, the zinc layer is easily dissolved, thereby protecting the steel substrate from corrosion. In the general atmospheric environment, the corrosion product of the zinc layer is usually basic zinc carbonate, which is difficult to dissolve, so it has a certain protective effect on the zinc layer.
