Hollow core slabs are precast, prestressed concrete elements that are generally used for flooring.
Some of there advantages are as follows :
Long spans up to 12 meters, no propping.
Flexible in design.
Light weight structures.
Floor Voids and Pentrations are available.
Trimmer Beams can also be used.
The slabs have between four and six longitudinal cores running through them, the primary purpose of the cores being to decrease the weight, and material within the floor, yet maintain maximal strength.
To further increase the strength, the slabs are reinforced with 12 mm diameter
steel strand, running longitudinally.
Currently we offer a range of four slab depths; 160, 200, 220, 250
and 260 millimetre slabs. Depending on the project requirements, in particular
span and loading performance, a particular slab depth is chosen.
Slabs with thickness of 160 millimeters :
Slabs with thickness of 200-220 millimeters :
Slabs with thickness of 250-260 millimeters :
