In order to specify the paints for corrosion protection such as Item No155 – such as PPG’s Sigma Etch, T Wash, or Item No168 – such as PPG’s SigmaDur 550, of structural steelwork in highway applications, the highways agency use a combination of item numbers for the primer, undercoat and top coat which stipulate the type of paint required.
This allows a selection of paint manufacturers to be considered when quoting for the works, ensuring that costs are always competitive. HAPAS certified, these BBA approved paint systems provide performance for over 15 years before major maintenance is required.
