Electrogalvanizing, also known as cold galvanizing, is a process that uses electrolysis to form a uniform, dense and well-bonded metal or alloy deposition layer on the surface of the workpiece.
Compared to other metals, zinc is a relatively inexpensive and easily plated metal. It is a low-value anti-corrosion coating widely used to protect steel parts, especially against atmospheric corrosion, and for decoration. Plating techniques include tank plating (or rack plating), barrel plating (for small parts), blue plating, automatic plating and continuous plating (for wire, strip).

Since zinc is not easy to change in dry air, and can produce a basic zinc carbonate film in a humid environment, this film can protect the internal parts from corrosion damage, even if the zinc layer is damaged by some factor. In some cases, zinc and steel combine over time to form a microbattery, with the steel matrix protected as a cathode. Summary Electrogalvanizing has the following characteristics:
1. Good corrosion resistance, meticulous and uniform combination, not easy to be entered by corrosive gas or liquid.
2. Because the zinc layer is relatively pure, it is not easy to be corroded in acid or alkali environment. Effectively protect the steel body for a long time.
3. After passivation by chromic acid, it can be used in various colors, which can be selected according to customers' preferences. The galvanizing is elegant and decorative.
4. The zinc coating has good ductility and will not fall off easily during various bending, handling and impact.
