Project Details

Steelcoat 100/400™ and Steelcoat 700™ Systems were all specified for the updated protection of a Northumbrian water aqueduct in a remote rural area. The work was carried out by Northumbrian Water’s approved contractors, UTS Ltd of South Shields.

The aqueduct spans 45m over a river and carries three 25″ diameter potable water pipes on the underside. It was built in 1898 and is a listed structure. This meant that part of the contract called for the new Denso coating to be closely matched to the original colours agreed by the local authority.

The water pipes and the underside of the aqueduct were protected with Denso Steelcoat 100 and 400 tape wrap systems. The Denso Steelcoat 400 System applied by UTS (following wire brushing to remove previous coatings) consisted of: Denso Hi-Tack™ Primer, Denso Profiling Mastic™, Denso Hi-Tack™ Tape, Denso Ultraseal™ Tape followed by a final two coats of Denso Acrylic Topcoat™. The steelwork on the main structure was protected using Denso Steelcoat 700 System which consists of Denso ST™ Epoxy followed by a topcoat of Denso™ Weathershield. This Denso topcoat was supplied in the special colours agreed to by the local authority in compliance with the listed structure regulations.
