With impressive corrosion resistance properties, zinc is commonly chosen as a protective coating on a number of components that have to withstand harsh environmental conditions and not succumb to rust and corrosion.

The process of zinc thermal spraying involves melting zinc or zinc alloys and spraying them onto a prepared substrate, creating a sacrificial corrosion resistant protective layered coating. The process is used in numerous applications where sacrificial corrosion resistance is required. This includes steel structures, offshore bolts, bridge fittings, bridge bearings and vehicle subframes to name but a few. For example, the zinc thermally sprayed bridge bearings on the Menai and Seven bridges survive 50 years when sealed.

Zinc spraying also allows for a thicker coating to be applied, which extends the component's lifespan making them functional in tougher environments.

As well as giving extended corrosion protection on steel fabrications and castings (up to 50 years), thermally sprayed zinc provides electronic shielding from small handheld devices to military communications equipment.

Numerous BENefits

There are a number of benefits to our zince thermal spray coatings when compared to traditional dip galvanising.

  • Ideal for large or irregularly shaped components that won't fit into a dipping tank.
  • Flexibility - components can be zinc sprayed at the metal fabrication workshop or on site.
  • Zero risk of heat warping.
  • Thicker coatings means component is able to withstand harsher environments.,
  • Process is faster and is less expensive than dip galvanisation.
