Cellular Beams are most commonly used as floor beams; this enables the designer to achieve long clear spans, service integration and a shallower overall floor depth. With cellular beams clear spans varying from 12m to 20m can now be easily achieved at the same depth and cost as short spans. Long spans often require the specification of costly pre-cambers but cellular beams can easily be pre-cambered as part of the manufacturing process without any additional costs.
