In the construction of modern buildings, cellular beams are able to span wide areas and can be made part of the design language of the structure, enabling architects to implement new aesthetics into steel structures. Greg North, current Regional Chairman of the BCSA (The British Constructional Steelwork Association) and Commercial Director for Barnshaws, one of the UK's leading producers of straight and curved cellular and Porthole Beams™ lays out the options for cellular beam construction and the associated merits of each approach. A number of production methods can be employed to create both straight and curved sections however, each has its own advantages depending on the demands of the application. Cellular and Porthole Beams™ have become a mainstay in construction projects across the world, providing added strength, reduced weight and convenient options for integrating building facilities.
