Westok CELLBEAM is a proprietary product of Westok Limited. It is implemented in the RAM Structural System. The Westok CELLBEAM is created by cutting a standard beam section in half longitudinally in a semi-circular pattern, separating and offsetting the two halves, and welding them back together. This results in a deeper beam of approximately the same weight as the original, with round openings along the length of the beam.
