How to choose cold galvanizing vs hot galvanizing?

Zinc plating refers to a surface treatment technology that coats a layer of zinc on the surface of a metal, alloy or other material to perform aesthetics and rust prevention.

For CARING’s customers, many of them are interested in the galvanizing process. The following article will introduce the galvanizing process and the difference between hot-dip galvanizing and cold-galvanizing.

Zinc-half of the world’s zinc is used for galvanizing.
Zinc is easily soluble in acid and soluble in alkali, so it is called amphoteric metal. Zinc is hardly changed in dry air, so it’s widely used in the zinc plating industry.
For our material handling equipment, zinc coating is mainly used to prevent corrosion of steel, and its protective performance has a great relationship with the thickness of the coating.

The rust-treated steel is placed in a zinc bath at about 500 ° C to allow the zinc layer to adhere to the surface of the steel structure.
