Hot Dip Galvanise

Hot Dip Galvanizing is the process of applying of Zinc coating to iron or steel surface for protection against corrosion. During the galvanizing process a series of alloy layers are formed due to a metallurgical reaction that takes place between steel and zinc. The zinc coating protects the base metal by acting as an impervious shield between the metal and atmosphere and provides additional protection even when moderately sized areas of base metal surface are exposed.

First step is the preparation of the material to be galvanized. In the galvanizing process materials are subject to very high temperatures. To avoid any potentially explosive situation it is therefore necessary that the materials to be galvanized are fabricated such that there are no blind corners, sealed tubes or any other such area.
