The difference between zero spangle and regular spangle galvanized steel sheets

Definition of 1.

Zero spangle galvanized steel sheet and regular spangle galvanized steel sheet are by soaking the steel sheet in molten zinc, so that the surface is plated with a layer of zinc, the steel sheet to prevent oxidation corrosion. The difference lies in the different composition of zinc liquid during production.

2. production process

The production process of galvanized steel sheet without regular spangle is different from that of galvanized steel sheet with regular spangle. The molten zinc temperature of the zinc-free galvanized steel sheet is higher in the molten state, so the surface of the steel sheet coating is smoother and there is zero spangle residue. The zinc liquid temperature of galvanized steel sheet with regular spangle is low, and there is regular spangle residue on the surface of the steel sheet.

3. appearance characteristics

There is zero spangle on the surface of galvanized steel sheet, the appearance is relatively smooth, the galvanized layer is uniform, and it has anti-corrosion effect. The surface of the galvanized steel sheet with regular spangles is not as smooth as the galvanized steel sheet without regular spangles, and the galvanized layer is not as uniform as the galvanized steel sheet without regular spangles.

4. use scenarios

Zinc-free galvanized steel sheet is used more in scenes with particularly strict appearance quality and appearance requirements, such as refrigerators, washing machines and other home appliances, automotive exterior parts, building materials, etc. Galvanized steel with regular spangles is used more in some occasions where the requirements are not too strict, such as furniture, daily necessities, etc.

In summary, the difference between zero spangle and regular spangle galvanized steel sheets is mainly in details, such as surface smoothness, galvanized layer uniformity, and appearance requirements. Choosing a suitable galvanized steel material in different usage scenarios can better meet the needs of users.
