Thermal SprayingMetal Coating (also known as Thermal Spraying) is used for the bonding of hot Zinc, Aluminium or various amalgams to blast cleaned surfaces.

It is generally used when hot-dip galvanising is not possible because the fabrications are too complex or may distort.

As in the case of Aluminium welding of like metals, to prevent stress corrosion cracking.

This treatment is specified by Network Rail, the Highways Agency and the Water Authorities as the base layer for further paint coats, particularly on immersed fabrications.

We have recently completed the thermal spraying of all the core welds for the M.o.D. on their BR90 bridging project using an amalgam of Aluminium and Zinc on Aluminium fabricated modules, which have a life expectancy of 30yrs.

Radleigh Metal Coatings are members of TSSEA ( The Thermal Spraying and Surface Engineering Association.

Thermal spray coating is used on smaller and intricate fabrications and can act as a replacement for galvanizing. It is applied in accordance with ISO 22093. It is also used on very large bridge structures and lighting columns for the Highways Agency.

Other applications include thermal spraying of trailer chassis, chimney stacks, exhausts and silencers.
