Fluoropolymer technology protects world first double helix bridge

Fluoropolymer technology protects world first double helix bridge

Dulux PC was thrilled to provide the coatings system for the world's first double helix bridge, delivering both finish and durability with the fluoropolymer binding technology in Quantum V90.

The $40-million Lachlan's Line Bridge is set to become an iconic landmark in Northern Sydney.

Sprialling above the M2 motorway, the boldly designed steel bridge provides pedestrians and cyclists with safe passage between North Ryde Railway Station, Macquarie Park and the new Lachlan's Line residential precinct.

The vibrant blue colour and corrosion protection were key factors in creating the three-step treatment for this engineering and architectural work of art, and each product was made to order for the project.

A topcoat of Quantum V90 in Dulux Arena Blue followed a primer coat of Dulux Zincanode 402 then a coat of Duremax GPE MIO (micaceous iron oxide), each adding their own protective qualities.

Dulux PC's Vijesh Maharaj says the fluoropolymer technology is ideal for high-traffic infrastructure exposed to the weather. 

"We recommend Quantum V90 for high demand areas such as commercial facades, road and rail infrastructure, retail complexes, high rise offices and apartments," Vijesh explains.

"For asset owners, it can reduce upkeep costs by significantly extending maintenance times. It offers excellent UV protection, gloss retention and graffiti resistance."

The bridge and the new residential precinct is a project by Landcom, the property development arm of the NSW Government.

The 178-metre bridge was factory sprayed in four mammoth parts by S&L Steel then transported to the site for construction by in a joint venture by Arenco and Daracon Group.
