In 2013 Winn & Coales (Denso) Ltd. supplied their Steelcoat 100/400™ System to protect a gas pipe on the Craigavon Bridge in Derry City. The successful application led to the use of the same system by Northern Ireland Water to protect 281m of a wastewater pumping main, including flanges and support brackets, on the same bridge in 2022.

The Steelcoat 100/400 System has been used by water companies throughout the UK to provide effective, long-term protection from corrosion to exposed and above ground pipework. The ease and speed with which the system can be applied, alongside minimal surface preparation requirements, also helped to reduce traffic disruption on the bridge during the works. The final layer of Denso Acrylic Topcoat was also supplied in the same shade of blue to match the colour already featured on the bridge structure.

Winn & Coales (Denso) Ltd. provided training and site support during the application which was carried out by BSG Civil Engineering Ltd and O’Kane Civil Engineering over a 10-week period. The products were supplied by one of Winn & Coales (Denso) Ltd.’s distributors, APP Fusion Group, Lisburn.
