Direct Channel supplies heavy-duty cable trunking engineered to protect and route electrical cabling in demanding commercial, industrial and residential installations. Manufactured from high-quality pre-galvanised steel, our cable trunking resists mechanical impact, dust and water ingress far better than PVC alternatives — so you get a secure, professional and long-lasting finish.
Our 50mm x 50mm steel trunking comes in 3-metre lengths with a robust wrap-over lid secured by quick-action turnbuckle lock nuts, so installation is fast and reliable. Because it’s steel, it also suits surface-mounted runs where strength, longevity and fire performance matter — for example, plant rooms, workshops, riser cupboards and back-of-house cabling.
Trunking Accessories & Fittings
We also stock a full range of matching cable trunking accessories, so you can complete the run from a single supplier:
- Couplers
- End caps
- Threaded rod hangers
- 90-degree bends (top lid, inside lid, and outside lid options)
Every component is designed to fit together, so your installation stays neat, secure and compliant.
Cable Trunking Sizes & Capacity
Cable trunking is specified by its cross-section — for example, 50×50, 75×75 or 100x100mm. When sizing a run, remember that BS 7671 and the IET On-Site Guide (Appendix E) recommend cables occupy no more than 45% of the trunking’s internal cross-sectional area. So always allow room for future cables and heat dissipation. Not sure which size you need? Then our UK-based team can help you specify the right cable trunking for your cable schedule.
