How is the load-bearing capacity of a trunking system determined?

Load capacity is calculated based on material gauge, span distance, and the geometric profile of the trunking. To ensure structural rigidity under heavy cable loads, our systems incorporate Longitudinal Stiffening Ribs (also known as Swaged Ribs). High-capacity configurations typically feature two swages on the base and a dedicated stiffening rib on each side-wall to prevent lateral buckling and longitudinal sagging.
