What is galvanising?

Hot dip galvanising is the process of coating steel with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 450 °C. During the process, a metallurgically bonded coating is formed which protects the steel from harsh environments, whether they be external or internal.

Galvanised steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel and can be identified by the crystallised pattern on the surface (often called a ‘spangle’). Galvanising is the most environmentally friendly process available to prevent corrosion.

Why do I need it?

Galvanising should be used in coastal and heavy industrial areas. Salinity in the air can make non galvanised products oxidise and rust.

Does your guarantee cover coastal areas on non galvanised products?

No. Our guarantee will not cover any non galvanised steel products that fall within a 30mile radius of the coast.
