Course Content

Weathering steel has been used in bridge construction since the 1930s- it has been used extensively in North America, Europe and Japan for over 55 years and over the last 10 years in New Zealand.

In Australia, the Berry to Bomaderry stretch of the Princes Highway on the NSW South Coast has seen two bridges constructed featuring long span trough girders manufactured from BlueScope’s weathering steel which is known as REDCOR® weathering steel. The value weathering steel can offer for bridge design internationally is echoed in the learnings from the NSW South Coast Princes Highway upgrades including key benefits in the constructability and maintenance solutions offered using BlueScope’s REDCOR® weathering steel as explored throughout this case study.
