Hollow Core Concrete Trimmer Beams permit for the inclusion of very large floor voids, without the need to add additional columns, with adjacent planks on either side of the void designed to carry the extra imposed load. Hollow Core Concrete Trimmer Beams can be designed to appear as a steel lintel, and can also be utilised as an in-situ concrete beam, that can be cast together with topping screed. This trimmer beam range is especially designed to support both Hollow Core’s precast concrete slabs an also any adjoining precast stairs.

Penetrations and floor voids can easily be designed and incorporated within Hollow Core slabs. Penetration widths completely depend upon the position of penetrations, as well as the span and load requirements of the structural layout. Smaller service pipe penetrations can usually be accommodated after the slabs have been placed, while trimmer beams might be needed if bigger penetrations are needed.
