Bridging the gap between specifications and finish in Margaret River

Bridging the gap between specifications and finish in Margaret River

Through customised coatings systems, Dulux PC's technical consultants can help clients meet government specifications while achieving the desired finish.

On a major road project in Western Australia's famous Margaret River region, our team worked with Main Roads WA (MRWA) to meet its anti-graffiti and steel protection specifications for two new bridges.

The 96-metre long road bridge and seperate pedestrian bridge were constructed as part of the $58 million Margaret River Perimeter Road, diverting large trucks and traffic away from the tourist town's centre.

With a proven record of protecting road assets from graffiti, Weathermax HBR led a multi-product solution recommended by Joel Bock, Dulux PC's Business Development Executive for the Mining and Heavy Industrial sector.

Joel says three different coatings systems were required for various parts of the bridges, all with a focus on long-term durability.

Durezinc i90 was applied under the bridges' beams. "This two-part self-curing product helps resist corrosion in the most aggressive industrial and marine environments," Joel explains.

"For the external steel, our flagship three-coat system of Zincanode 402, Duremax GPE MIO and Weathermax HBR was selected. The anti-graffiti properties and proven effectiveness of Weathermax HBR were crucial factors for the client."

Both systems met the requirements within MRWA's Specification 835 for the Protective Treatment of Steelwork.

For the bridges' concrete elements such as piers and abutments, Dulux PC met the anti-graffiti requirements in MRWA Specification 908 with Durebild STE and Weathermax HBR.

Weathermax HBR has been successfully used as an anti-graffiti coating on other road assets throughout Western Australia. Known for its excellent gloss and colour retention over extended service periods, it can be applied over a wide range of suitably primed substrates including mild steel, galvanised steel, concrete and aluminium.

Weighing 500 tonnes in total, the bridges were fabricated by Fremantle Steel. The applicator Kaefer Novacoat sprayed the steel coatings in a controlled shop environment before on-site construction.

The concrete elements were coated on site. Painters from Nanokote WA brushed and rolled on the anti-graffiti protection. They also applied some 'touch up' repairs to the steel coatings following construction.

Funded through the WA Government's 'Growing our South' initiative, the perimeter road delivered safety improvements and reduced traffic congestion in Margaret River.
