What is Electro Galvanized Steel?
What is Electro Galvanized Steel? What is galvanizing? Galvanizing refers to a rust-prevention method of attaching metallic zinc to the surface of iron or steel. Zinc is a highly corrosion-resistant metal that insulates iron from contact with oxygen and water, thus preventing the chemical reactions needed for iron to rust. Since zinc is more metallic active than iron, it can prevent iron from rusting in a sacrificial electrochemical way, even if the plating layer is damaged. Classification of galvanizing The main methods of galvanizing are hot-dip galvanizing (HDG), electro galvanized (EG) and cold galvanizing. According to archaeological finds, iron was galvanized as early as the 1680s. Hot dip galvanizing (HDG) Hot dip galvanizing is to immerse steel materials in molten zinc liquid to form a zinc coating on the surface of the steel. This method can provide a thick and uniform zinc layer and is suitable for the anti-corrosion treatment of most steel products. Cold Galvani...
