Detailed explanation-1: -Answer : Zinc metal is used for galvanising iron because it is more reactive than iron. It reacts with air to form a hard layer of zinc oxide, which prevents air and moisture to come in contact with iron.
Detailed explanation-2: -Zinc is the primary component of the hot-dip galvanized coating. But to only recognize zinc as it is used in the galvanizing process would be a huge disservice to the natural, healthy metal. The silvery, blue-gray vital metal is abundant, essential, common, and even more importantly infinitely recyclable.
Detailed explanation-3: -Galvanisation is when a protective zinc coating is applied to steel or iron, to prevent rusting. The most common method is hot-dip galvanising. This is when metal parts are fully submerged in a bath of molten zinc.
Detailed explanation-4: -Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting.
