Hot Metal Spray Coatings

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

It is a process where zinc, aluminum, zinc85/aluminium15 or other alloys are sprayed onto a substrate, providing a highly protective coating or even as a desired architectural finish.

Coatings can be applied to not just metals but plastics, ceramics, concrete surfaces and a range of other substrates.

How does hot metal spray work?

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 particles are propelled onto the substrate solidifying into a highly protective 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.

What are the benefits?

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 .

(A new Australian Standard AS2312.3 dedicated solely to Thermally Sprayed Metallic Coating is pending release)

  • 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.
  • Slip Resistant finish that meets requirements of AS/NZS 4586.
  • 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.

What types of material can be hot zinc sprayed?
