Due to the fact that hot dip galvanizing has been used to protect iron/steel for such a long time, there are a variety of terms that have been used to describe the process, including galvanisation, galvanising and hot dip galvanization.
Hot dip galvanizing offers coverage both externally and internally within hollow sections, it self-repairs when damaged, sacrifices itself to protect the base metal, is environmentally sustainable, has good impact and abrasion-resistance and a maintenance-free life of 50 years or more. Galvanized steel is widely used in applications where corrosion resistance is needed and can be identified by the crystallised pattern on the surface (often called a ‘spangle’).
Recent reductions in the aggressiveness of the atmosphere towards zinc, and the stability of costs of applying the coating mean that hot dip galvanizing today costs less and lasts longer! There are more than 60 hot dip galvanizing plants in the UK and Ireland.
