ASD Westok Limited
Westok are the inventors and world-wide patent holders of cellular beams. A cellular beam is the modern version of the traditional ‘castellated’ beam. A Universal Beam or Universal Column is castellated which results in a beam approximately 40-60% deeper than its parent section. The exact finished depth, cell diameter and cell spacing are very flexible. A cellular beam is up to 2.5 times stronger than its parent section.
Established in 1985, Westok are  members of the British Constructional Steelwork Association (B.C.S.A) and The Steel Construction Institute (S.C.I). Westok became part of the ASD metal services group of companies in 2007.
