It is called HOT-DIP GALVANIZING the process of cleaning and subsequent dipping of iron or steel pieces into liquid zinc.
Under de regular conditions of GALVANIZING, during the immersion, several layers of Zn-Fe alloy are formed, and the last one (external) is constituted by pure zinc.
All types and shapes of steel, iron or cast iron can be galvanized with the following advantages:
– Zinc corrodes only 3 to 10% in relation to bare steel exposed to air and corrosion speed is known for several kinds of atmosphere, in way that maintenance-free lifetime can be safely stablished.
– The Zn-Fe alloy layer, in between metal base and zinc’s external layer, is almost as hard as steel, in which the resistance of the coating is noticed.
