Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten zinc.

It is zinc because Galvanizing is a type of technique to prevent corrosion, As iron is more prone to rusting (when exposed to atmospheric air), Zinc, on the other hand, is resistant to corrosion. So, in order to protect the galvanised iron sheets from rusting, a layer of Zinc is being applied on top of it & mechanical industries used most commonly this process some time they called plateauing or blackodizing and galvanizing main purpose of this process to protect the vessel/job from rusting/corrosion zinc and other non famous materials are there but zinc has the best property of corrosion resistance as compared to other has more advantages.

What is galvanised?

Because zinc prevents oxidation that's why or what?

Zn is not effected by moisture. So it used as coating of iron sheet.

Rakesh said:   7 years ago
A coating of zinc is given to prevent iron from coming in direct contact with air and so as to prevent rusting.

Because of rusting the iron losses it's property and strength.
