From iconic structures such as the Sydney Harbour Bridge to essential pedestrian and cyclist overpasses, bridges are major assets that require ongoing protection and maintenance.
Bridge asset owners, including local councils and state government agencies, commonly face a wide range of maintenance challenges. These include:
- Corrosion
- Graffiti and its frequent removal
- High traffic
- Extreme UV exposure
- Pollution and grime
- Adherence to mandated specifications and standards
- Maintaining colour and appearance
- Minimising maintenance disruptions
- Achieving extended maintenance cycles
Protective coatings can significantly increase a bridge’s durability, extend its lifespan and reduce maintenance costs by addressing these challenges.
Leading products, tailor-made solutions
Dulux® Protective Coatings’ high-performance products for bridge protection include primers, intermediate and topcoats designed to resist corrosion in severe and marine environments, offer rapid dry and overcoat times, resist extreme ultraviolet exposure and repeated graffiti removal, provide barrier protection, and deliver excellent gloss and colour retention.
Dulux® Protective Coating systems are backed by advice and support from the company’s team of experts.
Protecting Australian bridges
At Kangaroo Point Green Bridge in Brisbane, a Dulux® Protective Coatings three-coat PUR5 system protects this pedestrian bridge’s structural steel. The system was selected to deliver maximum durability, an extended maintenance cycle of up to 25 years to first maintenance, plus a glossy off-white aesthetic.
Importantly, the system complies with the Queensland Department of Transport and Main Roads’ specification requirements.
“In a C3/C4 corrosivity category like this, having an extended time to first maintenance of 25-plus years is understandably very important to the asset owners,” said Dulux® Protective Coatings Queensland Sales Manager Brendan Lichtendonk.
In Melbourne, the iconic West Gate Bridge was first coated with Dulux® Protective Coatings products more than 40 years ago. As well as being buffeted by high winds, the bridge sustains large traffic volumes, which produce significant pollution and grime and was remediated in 2020 and 2021 with a four-part and stripe coat system.
“Our sophisticated coating system provides a superior-level durability and will help the West Gate Bridge look good for another 40 years,” Dulux® Protective Coatings Specification and Projects Manager Daniel McKeown said.
In Perth, a Dulux® Protective Coatings system is safeguarding the steel and concrete substrates on the Mint Street Overpass. Asset owner Main Roads Western Australia sought a robust coatings solution to counter ultraviolet exposure, corrosion, graffiti and the daily rigours of foot traffic.
A quick turnaround time was also essential.
“The bridge couldn’t be closed for too long,” Dulux® Protective Coatings Business Development Executive Michael Filmer said. “The new Dulux Luxafloor Express range was the obvious choice to minimise downtime. It offers fast drying capability and can achieve a full cure in one day.”
