Galvanizing

Steel

Galvanizing is the word given to the process of applying a thin layer of zinc or zinc-aluminium alloy to steel thus providing corrosion resistance. The two principal coating methods are continuous galvanizing and batch (or general) galvanizing. Continuous galvanizing is used to coat flat-rolled steel (mostly cold reduced, but some hot rolled), and also wire and tube. Zinc is applied either by hot-dip coating (the steel passes through a pot of molten zinc) or electrolytic coating (deposition takes place in a series of electrolytic cells). Hot dip is the most common method as it is cheaper.
