Zinc is used in galvanizing because zinc can be made to stick to iron and does not rust. In addition, when you cut it, the zinc will cover the iron at the point where it is cut.The whole process makes sheet iron last much longer.xists and is an alternate of. Merge this question into.

The process of welding galvanized steel is commonly found in the metal fabricating industry. Many welders will be required to weld galvanized steel at some point in their career; and in doing so they may experience galvanize poisoning or metal fume fever.alvanize poisoning is a condition that results from the over exposure to zinc oxide. Zinc oxide is formed when the steelâs galvanized coating evaporates from the high heat used in welding. Galvanized steel is iron that has been coated with zinc.
