What is Galvanising?

Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, in order to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten hot zinc. When hot-dip galvanizing older metala that have been recycled from another project, the metal may seldomly be in bad shape or be badly corroded. However, so long as the metal sections are structurally sound and healthy for purpose, it is still viable to be refurbished and hot-dip galvanized. Stainless steel lasts much longer than galvanized steel, so when the longevity of the building project is of importance, using stainless steel is recommended. Stainless steel is much stronger than plain hot-dip galvanized steel.

What is the process of galvanising?

Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. Galvanized steel is made when regular carbon steel is coated with a thin layer of zinc. This coating is created with one of two methods;  electrogalvanizing or hot dipping. This zinc layer helps to prevent corrosion and rust. Galvanized steel costs less than stainless steel, however, it is weaker.

What is the advantage of galvanising a metal?

Galvanizing offers:

Durability – a permanently-bonded tough coating. Data shows that galvanizing can provide between 34-170 years of protection for steel.
Hygienic – easy-to-clean surface.
Long life - 70 years, plus maintenance-free.
Economic – lowest overall cost compared to other coatings.
