What Are the Categories and Performance Characteristics of Galvanized Sheets?

Galvanized Steel Sheets are steel plates that have a layer of zinc applied to their surface, either through cold rolling or hot rolling. This zinc layer acts as a barrier, preventing the steel from coming into contact with air and moisture, thereby preventing rust.

- By production process: Hot-dip galvanized steel (steel plate dipped into molten zinc for galvanization) and electro-galvanized steel (zinc layer deposited on the steel plate surface through electrolysis). Hot-dip galvanized steel has a thicker zinc layer and stronger corrosion resistance; electro-galvanized steel has a smoother and cleaner surface with a thinner zinc layer.

- Divided by the surface state of zinc coating: ordinary zinc flower, fine zinc flower, zinc-free flower, zinc-iron alloy, etc. The galvanized sheets with different zinc flower states have slight differences in appearance and performance, which can be selected according to specific usage scenarios.

Galvanized Sheet: Performance Features

- Corrosion Resistance: The zinc layer, acting as a sacrificial anode, corrodes first, thereby protecting the steel substrate. The lifespan of hot-dipped galvanized steel plates typically exceeds 10-15 years (even longer in dry conditions), effectively extending the product's service life.

- Processing Performance: Offers excellent stamping, bending, and welding capabilities, catering to a variety of processing requirements and suitable for manufacturing complex-shaped components.

Coating Performance: The surface zinc layer combines well with paints and other coatings, facilitating subsequent coating treatments and enhancing the product's aesthetics and protective properties.
