Precast concrete beam, prestressed (Specified by section size)
Prestressed precast concrete beams are structural elements manufactured in controlled factory conditions using high-strength concrete (50-100 MPa) and high-tensile steel strands (1860 MPa). The prestressing force induces compression in the concrete, allowing longer spans, reduced deflections, and crack control. Available in standard profiles (T-beams, I-beams, rectangular) or custom designs, these beams comply with AS 3600:2018 and AS 5100 for infrastructure applications.
- Bridge girders and infrastructure
- Long-span commercial buildings
- Industrial warehouses
- Multi-storey car parks
- Stadium and grandstand structures
- Marine structures and wharves
- Railway sleepers and infrastructure
- Architectural facades
- Post-tensioned floor systems
Prestressed concrete was introduced to Australia in the 1950s with the Warragamba Dam ice tower (1953). The technique was pioneered by the formation of the Australian Prestressed Concrete Group in 1962, which evolved into the Concrete Institute of Australia in 1969. Early applications included the Gateway Bridge Brisbane and numerous infrastructure projects. Australian development has focused on durability in aggressive environments, leading to world-leading standards for marine and infrastructure applications with 100-year design life requirements in AS 5100.
