Home improvement hardware that helps installers create reliable support and mounting runs, supplied as a practical pack for repeatable fittings. Confident, consistent installation reduces on-site faff for tradespeople and keen DIYers. Is Direct Channel Slotted Channel the right choice for your load and corrosion requirements?
⚡ At a Glance
- • Load Capacity: Heavy-duty 2.5mm mild steel construction gives increased rigidity for supports
- • Best for: DIYers and installers needing consistent, standard strut lengths for shelving and cable runs
- • Not ideal for: Environments that demand stainless steel corrosion resistance for long-term outdoor exposure
Slotted channel measures 41 x 21mm with 2.5mm thickness and a 1 metre length. Slots are 11mm x 25mm at 50mm centres, supplied pre-galvanised and sold as a pack of four.
Quick, adjustable mounting - with regularly spaced 11 x 25mm slots
Slot pattern at 50mm centres allows bolts and fittings to slide into position along the channel. The 11mm x 25mm cutouts accept common bolt sizes and bracket tongues.
Fast alignment and repeatable fixing points speed up installation and make on-site adjustments straightforward.
Stiff and stable support - with 2.5mm heavy-duty mild steel
2.5mm section thickness combined with a 41 x 21mm profile increases bending resistance compared with thinner strut. Mild steel construction keeps the profile rigid under typical shelving and cable tray loads.
Reduced flex under load offers dependable support for shelving, conduits and light framing when properly fixed to structure.
Everyday corrosion protection - with pre-galvanised finish
Pre-galvanised coating on mild steel gives a zinc layer that slows surface rusting in sheltered and indoor settings. The finish is suitable for general building interiors and covered installations.
Good resilience for indoor and sheltered uses, while applications needing long-term outdoor exposure should consider more corrosion-resistant materials.

A: Slots measure 11mm x 25mm at 50mm centres, and each length is 1 metre, supplied as a pack of four.
🏆 Our Verdict
Suitable for tradespeople and DIYers who need standard, repeatable strut lengths for shelving, cable containment and light framing. The key selling point is the heavy-duty 2.5mm mild steel profile with pre-galvanised protection and regularly spaced slots, supplied as a convenient pack of four. Shoppers should compare options for outdoor corrosion resistance, however the robust construction and standard sizing deliver solid long-term value for indoor installations.
