Hot Metal Spray

Hot Metal Spray Coatings in Sydney & Eastern Coast of Australia

Hot Metal Spray or Thermal Arc Spray or Metallising, provides a superior quality finish with greater performance than painting or hot dipped galvanising.

The process of Hot metal spray is where zinc, aluminium or Zinc85/Aluminium15 or other alloys are sprayed onto a substrate, providing a highly protective sacrificial coating or even as a desired architectural finish. Coatings can be applied to not just metals but some plastics, ceramics, concrete surfaces and a range of other substrates.

Hot metal spray, available in Sydney, provides long-term corrosion protection to steel structures exposed to aggressive environments which can exceed the durability of the coating as determined under AS2312.2002.

  • Major Increases in longevity and protection from wear and corrosion damage. Outperforms Painting and Hot dipped Galvanising under ASTM B117 testing.
  • Coating has high heat resistance.
  • Coating can be applied without distorting the metal. Substrate material seldom reaches 95 degrees Celsius.
  • Unlimited Application Size.
  • Control of Coating Thickness. Thickness can be increased for increased protection.
  • At minimum equivalent in Durabability under AS2312.2002 to Hot Dipped Galvanising and Superior when increased thickness or Zinc / Aluminium alloy or Aluminium coating is specified.
  • Paintability and Finish. Paint can be applied immediately over metal sprayed finish to provide a high-level finish with extremely long corrosion resistance.
  • Paint Warranty over Metal Sprayed Coatings is easily obtained.
  • Metal Spray Coatings are solvent and VOC free.
  • Low Energy Consumption and minimal Waste by products compared to Hot Dipped Galvanising.
Two metal wires consisting of the coating material are melted by an electric arc in the gun and sprayed using compressed air onto the substrate. These splats are propelled onto the substrate solidifying into a highly protective metal coating. The coating can be a pure metal such as Zinc or Alumimium or an alloy of metals such as Zinc/Aluminium. It forms a mechanical bond to the substrate creating high adhesion coating. The formed metallic coating protects the steel from corrosion by both barrier and sacrificial coating.
Any type of steel or concrete structure, product, component or part can undergo the process of hot metal spray in Sydney and wider NSW. Some examples:

  • Bridge girders
  • Structures prone to distortion by galvanising process
  • Steel structures in Marine or Industrial Environments
  • Sculptures
  • Steel Structures requiring exceptional Corrosion resistance
  • Pedestrian and Bicycle trafficable steel walkways requiring non-slip
  • Distortion free Chequer plate flooring in external environments
  • Marine Vessels
  • Boat trailers
  • Car and truck components
  • Fireboxes

Why choose CCMP for Thermal Arc Spray?

CCMP is one of only a few companies that has the capacity and latest equipment for the application of thermal arc spray of zinc and/or aluminium for cost-effective life cycle protection of clients’ critical structures and assets. We have the ability to:

  • Collect your steel structure or product in one of our fleet of trucks and prime movers,
  • Prepare the surfaces for abrasive blasting, industrial spray painting , protective metal coating and abrasive blasting/sandblasting processes in Sydney, Newcastle and wider NSW in-house and in accordance with your specifications, and
  • Deliver your renewed and protected steel structure or product back to you.
  • Service any project (industrial or domestic), no matter how big, small or complex.

Once we have carried out sandblasting in Sydney or wider NSW, the exposed ‘raw’ steel is highly subject to immediate rust, even in transit. The benefit of having the abrasive blasting and protective metal coating completed at the one site is therefore obvious. As general rule of thumb, protective coating must be applied to steel within 4 hours of blasting.
