The most common method of galvanizing steel is by hot dip galvanizing, which involves the steel being submerged in a bath of molten zinc. This deposits a thick layer of zinc iron alloys on the surface of the metal, providing an effective surface protection against corrosion.

When steel is immersed in molten zinc at a temperature of around 450oC (842oF), a metallurgically bonded protective coating is formed. This galvanizing reaction only occurs on a chemically clean surface, making surface preparation essential to good quality coating.

Automated surface inspection offers a fast, accurate assessment of steel surface condition prior to galvanizing, detecting any defects that may affect the process. It also provides verification of product surface quality following the galvanization, ensuring the steel is fully protected from corrosion.
