Thermal metal spraying is widely recognised as one of the most superior coatings available for providing corrosion resistance along with extremely long service life. Twin wire thermal arc spraying involves the melting of 2 wires and propelling the molten or plasticised metal particles toward an abrasive blasted substrate. There, the particles instantaneously solidify to produce a dense metallic coating.
These coatings can be applied to thicknesses of 500µm plus. Most metallic coatings provide a service life relevant to their thickness, typically meaning that the thicker the coating, the longer the service life of the object that is coated. Metallic coatings can provide a service life from 5 to 50 years plus even in the harshest of environments. The most profound advantage of metallic coatings is they require no ongoing maintenance during their projected service life, unlike that of traditional paints.
Our thermal metal spray process is also used as an alternative to hot dip galvanising. Metal spray ‘galvanising’ does not utilise great heat or distortion, and can be selectively applied. This makes it ideal for repairs to existing hot dip galvanising, especially when applied to any thickness for greater localised protection, or masked to protect vital components.
