Galvanizing is the process of immersing steel in zinc at a temperature of 450 ° C. metallurgical bond of zinc alloys coated with a layer of pure zinc.
The first alloy gives great resistance to the base metal. The exterior of the zinc layer absorbs impact. While the inner layers provide corrosion protection.
