Hot dip galvanizing is a process in which metal is immersed into molten zinc to form a protective layer which completely covers the steel surface and seals it metallurgical properties and protect from the corrosive actions of its environment. This ensures greater resistance to corrosion and rust over a much longer period than any other form of coating.

Hot dip galvanizing is especially useful for metal works and surfaces that are subject to wear and tear, such as used in walkways, ladder rungs, chains, handrails, pipes, lamp poles, etc. In particular, it is most useful in enabling structural works to achieve outstanding toughness and resistance to corrosion.
