Hollow core slabs are precast, prestressed concrete elements that are generally used for flooring. Some of there advantages are as follows: 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; 200, 220, 300 and 320 millimetre slabs. Depending on the project requirements, in particular span and loading performance, a particular slab depth is chosen. | Technical Information Slab Type Definition:
F Depth.Cores.Bottom Strands.Top Strands An Example is F205.6.7.0, this is a Hollow Core Slab, of 6 cores, 7 strands and 205 mm depth.
The load chart (below) can be used to find the most suitable slab depth for your project. Using your required Load(kPa), and required span, choose a suitable slab depth. Then click on the Slab Type links (above), and choose a relevant Slab Type for your requirement. Click to enlarge.
