Metal/Thermal spray coatings are used for the protection of iron and steel in a range of corrosive environments. Long term effectiveness (over 25 years) in both Industrial and Marine applications have been documented.

Austenitic stainless steels, aluminium bronze, and cobalt and nickel base alloys, when sealed, offer varying degrees of atmospheric protection. The particular environment dictates the appropriate alloy selection.

Burj Al Arab Hotel

The iconic Burj Al Arab Hotel has had in total 10,000m2 of steelwork arc-sprayed over an intermittent six-month period.  The items sprayed included the heli-deck framework, roof mounted mast and 6 diagonal support braces, each weighing in excess of 200 tonnes.  The aluminium coating should guarantee a 15 to 20 year protection against corrosion in the harsh, coastal environment in which the Burj Al Arab stands.
