Hot Dip Galvanizing

 

Hot dip galvanizing is a very simple process that provides long term corrosion protection to steelwork. It involves cleaning steel and immersing it in molten zinc to obtain the coating. Hot dip galvanizing is the process of coating iron or steel with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 450°C.

During the process, a metallurgical bonded coating is formed which protects the steel from harsh environments. Hot dip galvanizing is probably the most environmentally friendly process available to prevent corrosion.

The main galvanizing process steps include:

1. Cleaning cycle – degrease and chemical clean

2. Fluxing – helps to wet the surface of the steel

3. Galvanizing – immersion of steel into bath of molten zinc

4. Post treatment – passivation and top coats

PROCESS RANGE:

  • Galvco Cleaners
  • Galvco Inhibitors
  • Galvco Fluxes
  • Galvco Passivates
  • Galvco Top Coat
