Hot Dip Galvanising

Safeguarding for the future

Hot dip galvanizing is the process of immersing metal in a bath of molten zinc at a temperature of around 450 °C to obtain a metallurgically bonded coating that can offer up to 100 years of corrosion protection.

The Process

Mettal work closely with trusted, expert partners to carry out hot dip galvanising for our clients.   

 

Hot dip galvanising is the process of coating iron, steel or ferrous materials with a layer of zinc. The process entails passing metal through a molten batch of zinc at a temperature of around 860â—¦f (460â—¦c), which further reacts with carbon dioxide (C02) to form zinc carbonate (ZNC03).

Protection

Zinc carbonate is a dull-grey, strong material that can arrest the corrosion process and protect the steel from the elements.

 

Galvanised steel is widely used in applications in which rust resistance is required. It can be identified by the crystallisation patterning on the surface, which is known as spangle.
