Electro galvanizing: also known as cold galvanizing in the industry, it is the process of forming a uniform, dense and well bonded metal or alloy deposition layer on the surface of the workpiece by electrolysis.
Compared with other metals, zinc is relatively cheap and easy to be plated. It is a low value anti-corrosion electroplated coating. It is widely used to protect iron and steel parts, especially to prevent atmospheric corrosion, and for decoration. Plating technology includes bath plating (or hanging plating), barrel plating (suitable for small parts), blue plating, automatic plating and continuous plating (suitable for wire and strip).
