Electro galvanized steel is made by applying galvanizing to the surface of cold rolled steel using an electrochemical method, it protects the steel against corrosion. It has different post-treatment options, including non-treatment, chromate, phosphate and anti-fingerprinting. Its typical applications include home appliances, vehicle outer panels and construction materials.

Manufacturing Process
Main Features
1. Good corrosion resistance, fine and uniform combination, not easy to be corrosive gas or liquid into the interior.
2. Because zinc layer is relatively pure, it is not easy to be corroded in acid or alkali environment. Protect the steel body effectively for a long time.
3. After chromic acid passivation, it can be used in various colors. It can be selected according to customers' preference. The galvanizing is beautiful and decorative.
4. The zinc coating has good ductility and will not easily fall during various bending, handling and impact.
The difference between electro galvanizing and hot galvanizing
1. There is a big difference in the amount of galvanizing between hot-dip galvanized sheet and electro-galvanized sheet. The amount of hot-dip galvanized sheet cannot be too small. Generally, the minimum is 50-60 g/m2 on both sides, and the maximum is 600 g/m2. The galvanized layer of the electro galvanized sheet can be very thin, the minimum is 15 g/m2.
2. Hot-dip galvanized sheet and electro-galvanized sheet are fundamentally different in the coating structure. There is a slightly brittle compound layer between the pure zinc coating of the hot-dip galvanized sheet and the steel strip substrate. When the pure zinc coating crystallizes, zinc flowers are mostly formed, and the coating is uniform and free of pores. The zinc atoms of the electro galvanized sheet layer are only deposited on the surface of the steel strip, and they are attached to the surface of the steel strip by physical action.
