Zinc Spraying

Zinc Spraying Steel – Hot Metal Spray Process

Zinc Spraying is ideal for larger item that cannot fit in to a galvanising tank.
E.g. Oversized steel structures, such as bridges, long I beams, Steel Trawlers / Boats.

Zinc spraying can achieve to the same level of rust protection as galvanising, excellent for untreated steel; it is fast drying with good filling properties.
Zinc spraying coupled with a correct paint system can give 20 years plus, of life for anti corrosive.

This process is often specified in preference to galvanising for its ease of application without the need for drilling drain or vent holes and to avoid the risk of distortion, especially on intricate work.

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 and spray it onto the item to be protected. This solidifies immediately leaving the perfect surface to stand up to all weathers.

Airless Spraying

The benefit of airless spraying over all other forms of applying a paint coating is that no or very minimal amount of thinner is added to the paint.
Airless spray is quite simply paint applied at great pressure, atomising the paint prior to pushing through the nozzle.
Applying primers through airless spray helps with penetration and even distribution on inaccessible and awkward areas.
A further advantage is that with no air mixed with paint in spraying there is no danger of having wet air and contaminating the paint being applied.
Using a high build specialist coating more than 600 microns of paint can be applied at one time, giving great anti corrosion properties, and conforming to many specified marine standard specifications. Typical application for airless spray are:

  • Bridge Painting
  • Container & Skip Painting
  • Intumescent Coatings for fire control
  • Structural Steel

We have a Qualified NACE Inspector on site

NACE certified coating inspector
For 25 years, the NACE Coating Inspector Program has set the standard for inspections in the protective coatings industry and is the world's most recognized coating inspector certification program. CIP is the first international certification program designed to improve the overall quality of inspections performed. We have invested heavily in the best possible test equipment to enable our in house inspector to produce accurate comprehensive paint and condition application reports.
