Zinc spraying is ideal for larger items that cannot fit into a galvanising tank. E.g. Oversized steel structures, such as bridges, long I beams, steel trawlers / boats, gates and railings.
Zinc spraying can achieve the same level of rust protection as galvanising, it is excellent for untreated steel; fast drying with good filling properties. Zinc spraying coupled with a correct paint system can give 20 years plus, maintenance free.
Hot metal zinc spray is heat resistant to 350ºC, spot-weld able, resistant to petrol, chemicals and weather influences.
Process of zinc spraying
Metal spraying is used to coat ferrous (steel) metals, with an anti corrosion coat of zinc or aluminium. Surfaces are first blast cleaned, to remove all corrosion and give the correct profile before metal spaying. The zinc wire is passed through a zinc pistol with oxygen and propane to atomise the wire to be sprayed onto the item to be protected. This solidifies immediately leaving the perfect surface to stand up to all weathers.
