Galvanizing process

The hot-dip galvanizing process consists in immersing steel parts in a bath of molten zinc to produce a protective coating on the steel. The zinc coating is not just a simple zinc deposit: it is metallurgically bonded to the steel base due to the metallic diffusion reaction which takes place between the iron and the zinc.

The hot-dip galvanizing process involves several stages:
  • Pre-treatment includes degreasing, pickling, rinsing and fluxing the steel

  • The part is then dried and preheated in a dryer

  • The galvanization stage itself consists of immersing the steel in molten zinc

  • An additional benefit of passivation is possible to prevent the appearance of wet storage stains on galvanized products exposed to moisture
