11/06: Hot dip galvanizing
Hot dip galvanizing is the process of coating iron or steel with a thin zinc layer. The process involves passing the steel through a molten bath of zinc at very hot temperature (around 460 °C). Zinc "rusts" to form zinc oxide, a fairly strong material that stops further rust, protecting the steel below from the elements.
11/06: What is Galvanizing?
Galvanizing is a protective coating for steel that is beneficial in providing long life, durability and preformance. Zinc coatings prevent oxidation of the protected metal by forming a barrier. This is a thick, tough metallic zinc envelope, which covers the steel surface and seals it from the corrosive action of its environment.
