What load-bearing capacity can be expected from the perforated design?

The perforated cable tray is engineered for both medium-duty and heavy-duty load classes as defined in IEC 61537, with safe working loads dependent on span, width, and side rail height. The pattern of perforations is optimized to reduce weight without compromising the beam strength of the side rails and base. Detailed load tables are available for each configuration, but typical installations can support dense cable bundles in power distribution and control circuits with deflection within permissible limits, ensuring safe and code-compliant installations.
