Hot dip galvanizing has grown almost continuously since it was first used to protect corrugated iron sheets 150 years ago.
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. During the process, a bonded coating is formed which protects the steel from harsh environments.
Galvanizing is probably the most environmentally friendly process available to prevent corrosion. Data shows that galvanizing can provide between 34 to 170 years of protection for steel.
