Strut Channel 41x41mm
Chinne Electric Strut Channel 41×41 mm is the industry-standard cold-formed C-channel framing system for supporting cable trays, cable ladders, conduits, pipes, ductwork, and heavy M&E services. With full 41 mm depth, it delivers higher load capacity than shallow 41×21 mm profiles—making it the preferred choice for trapeze hangers, multi-tier support frames, plant rooms, and demanding commercial and industrial installations.
General information
Product Features
- Industry-standard full strut: 41 mm wide × 41 mm deep—the most widely used strut profile in mechanical, electrical, and construction support systems worldwide.
- High load capacity: Full-depth section provides superior bending strength and span capability compared to shallow 41×21 mm half-strut—suited to heavy cable trays, large conduit runs, HVAC ductwork, and multi-service trapeze assemblies.
- Weld-free modular framing: Continuous slotted channel with inturned lip edges allows channel nuts, spring nuts, and brackets to be positioned anywhere along the length—no welding or on-site drilling for most connections.
- Complete system compatibility: Works with the full range of standard 41 mm strut accessories including angle brackets, beam clamps, cantilever arms, threaded-rod hangers, pipe clamps, and combination framing fittings.
- Adjustable, reusable, demountable: Support layouts can be modified, extended, or reconfigured during installation or future building upgrades without replacing the channel.
- Multiple duty ratings: Light-duty (typically 1.5 mm) for economical installations; heavy-duty (typically 2.5 mm / 12 gauge) for maximum strength applications.

Technical Description
Strut channel is a modular metal framing system consisting of a cold-formed C-channel section with inturned lip edges and a continuous row of slotted holes. Hardened, toothed channel nuts engage the inturned lips to create secure, adjustable connections at any point along the channel—enabling weld-free assembly of support frameworks using only wrenches and standard fasteners.
The 41×41 mm profile is the industry-standard full-depth strut and the most widely specified size for mechanical, electrical, and plumbing (MEP) support work. Its square cross-section delivers the highest load capacity within the 41 mm strut family, making it suitable for:
- Heavy cable tray and cable ladder suspension
- Multi-tier trapeze hanger assemblies
- Large-bore pipe and HVAC duct support
- Structural equipment mounting frames
- Seismic and lateral bracing applications (where specified)
- Industrial racking, shelving, and modular framing
In cable management systems, 41×41 mm strut channel forms the primary structural support from which cable trays, cable ladders, mesh trays, basket trays, and conduit systems are suspended or wall-mounted—typically using threaded-rod trapeze hangers, cantilever brackets, or direct channel-to-structure fixings. Channel support systems are governed by BS 6946; the cable trays and ladders they carry comply with IEC 61537 and related national standards.
Chinne Electric 41×41 mm strut channels are supplied in slotted and plain configurations, with material and finish options matched to indoor, outdoor, and corrosive-environment project requirements. Channels can also be combined in back-to-back or face-to-face arrangements to increase load capacity for demanding spans.

The 41x21mm shallow strut channel is a cold-formed C-channel with half the depth of a standard 41x41mm profile, specifically engineered for low-clearance ceiling runs, wall-mounted supports, and restricted-depth mechanical and electrical installations. Despite its reduced depth, it remains fully compatible with standard 41 mm strut nuts, brackets, and support accessories. The continuous slotted design with inturned lips enables adjustable, bolt-in-place fixing along the entire length, making it suitable for mounting cable trays, conduits, pipes, ductwork, and equipment brackets in space-constrained environments.
This strut channel conforms to the dimensional and performance requirements specified in IEC 61537, the international standard for cable tray systems and cable ladder systems. Additionally, the product references BS 6946, the British Standard for metal channel support systems. Dimensional tolerances, material grades, and mechanical load data are verified through type testing conducted at accredited third-party laboratories, ensuring reliable performance in building wiring, industrial equipment, and commercial installations.
The shallow-profile strut channel is designed for light-to-medium-duty mechanical, electrical, and plumbing (MEP) support applications where mounting depth is limited. Primary uses include cable containment systems, conduit and pipe supports, ductwork mounting, and equipment bracket installation in low-clearance ceiling voids and wall-mounted configurations. It is suitable for building wiring, industrial equipment setups, and commercial installations that require dependable structural support and compliance with international standards such as IEC 61537.
Yes, the 41x21mm strut channel maintains full compatibility with standard 41 mm strut nuts, brackets, and support accessories. The continuous slotted design with inturned lips allows for adjustable, bolt-in-place fixing along the full length of the channel. This interoperability ensures that installers can utilize existing 41 mm channel nuts and fittings without requiring specialized components, streamlining procurement and installation across projects involving cable tray supports, conduit mounting, and modular framing systems.
