Profile: ASD Westok Ltd. is a provider of cellular beams. Our cellular beams are used in applications such as columns, straight, curved and tapered roof, floor beams & bridges & scrapers. Our ultra shallow floor beams(USFB) combine the concrete slab within the depth of the steel beam in order to create shallow or slim floor construction. Our beams comprise pronouncedly asymmetric cellular tees to provide a wide bearing for either pre-cast units or a profiled metal deck.
