Colourgalv is a duplex coating that combines the corrosion protection benefits of hot dip galvanizing with the aesthetic beauty and colour of powder coating. The coating is suitable for most urban and rural locations throughout the UK and beyond. For coastal and offshore environments Colourgalv Marine is a triplex coating that incorporates an additional epoxy layer that provides additional protection in salt rich environments.
Colourgalv uses hot dip galvanizing (1) as a base to ensure that every surface of the steel is protected from corrosion. Polyester powder coating (3) adds additional protection whilst also providing a colour and texture.
Colourgalv Marine utilises the same performance benefits of hot dip galvanizing (1) and polyester powder coating (3) but adds an additional epoxy barrier coat (2) between the galvanizing and the topcoat. This ensures that the zinc coating does not oxidise in the salt rich environment
