Galvanized steel sheets are welded steel sheets with hot-dip or electro-galvanized layers on the surface, and are widely used in construction, home appliances, vehicles and ships, container manufacturing, and electromechanical industries.
Hot dip galvanized steel sheet (SGCC): immersion plating, bright white, small zinc flower, it is difficult to see the zinc flower, large zinc flower is very obvious to see the hexagonal flower block, the main characteristics: corrosion resistance Sex; lacquerability; formability; spot weldability. Uses: Extremely wide, small household electrical appliances, good appearance, but compared with SECC, its price is more expensive, many manufacturers have switched to SECC to save costs.
According to zinc, the size of zinc flower and the thickness of zinc layer can indicate the quality of galvanizing. The smaller the thickness, the better. Of course, don't forget to let manufacturers add fingerprint resistance. It is also possible to distinguish by its coating: such as Z12 means the total amount of double-sided plating is 120g/mm. E.g:
Galvanized steel sheet (SGLD): is a multiphase alloy material containing aluminum-rich and zinc-rich. Because of the characteristics of aluminum and zinc, it has better performance than hot dip galvanized steel sheet (SGCC). Main characteristics: corrosion resistance, its ability is much higher than SGCC; heat resistance; heat conduction and heat reflection; formability; weldability. Uses: used in some places where reflection is required, such as reflector inside the oven. The reflector of the electric cooker.Hot dip galvanized steel sheet (SGCC) is generally used, galvanized steel sheet (SGLD) is deep drawing, and SGCE is ultra deep drawing.
