Perfect Slabs – PRESTRESSED HOLLOW CORE CONCRETE SLABS

Hollow-core concrete slabs are pre-stressed concrete panels constructed with hollow cores running from end-to-end and reinforced with pre-stressed high-tensile steel wires. This combination of hollowcores, high-strength concrete and pre-stressing, results in a relatively light-weight durable and strong concrete slabs.
