What Is The Galvanising Process?│hot Dip Galvanising

Hot dip galvanising is the process of coating iron steel or ferrous materials with a layer of zinc by passing the metal through a molten batch of zinc at a temperature of around 860 f (460 c) which further reacts with carbon dioxide (C02) to form zinc carbonate (ZNC03) a usually dull grey fairly strong material that stops further corrosion
