Write about galvanisation

The protection of iron and steel from corrosion by coating with molten zinc. has been proved for a hundred and fifty years. This is called galvanizing. The zinc coating protects from the atmosphere the part’s surface, avoiding corrosion and weathering.

Galvanization helps extend the life of steel parts by forming a membrane between the metal and the air, preventing the accumulation of iron oxide on the steel layer. Galvanization also offers superior corrosion resistance to environmentally exposed parts.

The galvanizing process consists of three basic steps, namely surface preparation, fluxing and galvanizing. Material is loaded onto jigs before being immersed in molten zinc at about 450 degrees until the working temperature is the same as zinc. During this process, the molten zinc reacts to a series of zinc/iron alloys with the steel surface.
