Description

Hollowcore planks are precast, prestressed concrete elements manufactured using extrusion or slide-forming processes on long-line beds. Featuring 4-6 longitudinal cores that reduce weight while maintaining structural capacity, they are reinforced with high-tensile prestressing strands. Standard widths of 1200mm with depths from 150-400mm accommodate diverse loading and span requirements across commercial, residential, and industrial applications.

Hollowcore technology originated in Europe in the 1950s, introduced to Australia in the 1960s. Modern extrusion and slip-forming techniques developed in the 1970s-80s revolutionised production efficiency. Australian manufacturing now includes advanced prestressing systems and automated production lines, with recent investments in sustainable concrete mixes incorporating supplementary cementitious materials.
