What is the hot dip galvanized steel

Hot-dip galvanizing is a process of coating steel with a thin zinc layer which used to halt the formation of rust. The surface treatment is done by passing the steel through molten zinc at high temperature.It provides long-term protection for steel products.

The Zinc coating has corrosion resistance and sacrificial corrosion function which delay the production of red rust. The zinc coating of the hot dip galvanized steel is higher than electro-galvanized steel sheet so has better corrosion resistance.

We can supply the hot-dipped galvanized steel sheet and coil with slitting, shearing, blanking, degreasing and brushing, stretching and leveling, and metallurgical support.
