galvanise articleThe dictionary definition of galvanise is ‘to coat (iron or steel) with zinc.’ Hot dipped galvanising is a well-established process used to protect steel from corrosion by applying a layer of zinc.

Steelwork is immersed briefly in molten zinc with layers, usually of an even thickness, dense and metallurgically bonded to the steel. Thickness is typically .002-.006 in (50 – 150). There is however, another process that can be used to coat steel with zinc.

Metal spraying using arc spray or flame spray is an alternative method of coating with zinc (or many other materials) to hot dipped galvanising. All methods of metal spraying involve the projection of small molten particles onto a prepared surface, where they adhere and form a continuous coating.
