Most applications of cellular beams in South Africa are as roof beams. This has been influenced by the demand within the commercial sector for shopping malls, motor dealerships and sports facilities. Cellular beams are a perfect solution for curved roof applications, combining a considerable weight saving and a low cost curving process which eliminates the need for a specialist section bending company. In projects where cost and speed of erection have been the deciding factors, without exception cellular beams have been used in preference to traditional clear span solutions; such as lattice trusses, stub girders and tapered plate girders. This is simply due to the fact that cellular beams require much less fabrication time, their lightweight and also much shallower than the traditional clear span solutions.
