Bridges & Tunnels

Curved steel-framed boardwalk with handrails set among landscaped gardens in a public park.

When it comes to curving steel, we make the impossible look easy. Whether you need X-X or Y-Y orientation, we can roll beams to the tightest radii or deliver millimetre-perfect cambers. Our controlled rolling has supported some of Sydney’s most recognisable infrastructure, from the old Sydney Monorail and the Cross City Tunnel to the massive steel walers at the Sydney Desalination Plant.

You’ve probably walked across our work without even realising it. The Anzac Memorial Bridge Walkway, the Newcastle & Albert ‘Tibby’ Cotter Pedestrian Bridge, and the shared pedestrian and cycle pathway in Moore Park all showcase our craftsmanship.

We’ve also contributed to major projects like the Lane Cove Tunnel, where every curve and camber was built for lasting strength and safety. And because safety matters just as much as style, we supply robust screens that keep every structure secure and protected.
