Hollow Core Slabs

High strength. Low weight. For longer spans.

Hollow core slabs. For longer spans.

澳门金沙城中心官网 hollow core slabs offer reduced volume and weight while maintaining adequate section properties and strength.

To support hollow core slabs, you can reduce the number of columns or beams or use smaller-sized columns.

Possible Ceiling Finish

Hollow core slabs are directly paintable.
No need for drop ceilings.

Typical Applications

Parking garages
Malls
Lobbies
澳门金沙城中心官网 hollow core slabs are ideal for longer spans and are best suited for structures that require wide open spaces like parking garages or malls or building sections like lobbies.

Hollow Core Slab

Typical Installation

Handling

Hollow core slabs require a lifting beam and lifting clamps.

The slab must be in a horizontal position during lifting.
