In car parks the long spanning ability of cellular beams help create a building with minimal internal columns. This enhance the feeling of security as the area is more open and will have few barriers to sight lines. In addition, cellular beams can also be pre-cambered at not extra cost during production in order to offset the proportion of the dead-load deflection. Large pre-cambers allow for natural drainage of surface water, eliminating the need for additional screed. The large circular openings accelerate smoke dispersion as compared to solid-web beams and also make provision for service integration.
