Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), 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 parts are submerged in a bath of molten zinc. Galvanizing protects in two ways:

It forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal.

The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.

The zinc protects its base metal by corroding before iron, for better results application of chromates over zinc is also seen as an industrial trend.
