Metal Spraying (also known as Thermal Spraying) is a process used to apply pure Zinc, pure Aluminium or various alloys to a blast cleaned surface.
Thermal spraying protects and greatly extends the life of a wide variety of products in the most hostile environments and in situations where coatings are vital for longevity and integrity of essential equipment. This specialist applied protective coating is generally specified when hot-dip galvanising is not possible because the fabrications are too complex or distortion may occur during the galvanising dipping process.
Thermal spraying is carried out in a wide range of anti-corrosion and engineering markets, including oil and gas, construction, petrochemical and marine. The treatment is often specified for Offshore, Network Rail, the Highways Agency and the Water Authorities. Other applications include thermal spraying of trailer chassis, chimney stacks, exhausts and silencers.
Thermal spray coating can be used on smaller and intricate fabrications and can act as a replacement for galvanizing. It is applied in accordance with ISO 2063.
The variety of metallised coatings include finishing coatings, such as anti-corrosion or decorative coatings, and engineering coatings such as wear resistant and thermal barrier coatings, making it ideal for a variety of subsea and topside machinery and apparatus.
