Product Description
Zinc plating (also known as electro-galvanising) is a process where zinc is applied by using a current of electricity. While is does provide some rust protection, its thinner coating is not as rust resistant as hot dip galvanising. Its main advantage is it is cheaper and easier to weld.
Application description
Electrogalvanizing, also known as cold galvanizing in the industry, cold galvanized sheet is mainly used in agricultural machinery, grain storage and high-speed guardrail and other industries in life. Its outstanding characteristics are low cost and high added value.
