Strut Channel 41x21mm

• Shallow half-strut profile: 41 mm wide × 21 mm deep—approximately half the depth of standard 41×41 mm strut. Suited to light-to-medium-duty loads where reduced installation height is required.
• Modular, weld-free framing: Continuous slotted channel with inturned edges allows channel nuts and brackets to be positioned anywhere along the length—no welding or site drilling for most connections.
• Wide system compatibility: Works with standard 41 mm strut accessories including spring nuts, channel nuts, angle brackets, beam clamps, threaded-rod hangers, and pipe/clamp fittings.
• Flexible installation: Suitable for wall, ceiling, and steel-structure mounting; layouts can be adjusted, extended, or reconfigured during installation or future upgrades.
• Multiple duty ratings: Available in light-duty (typically 1.5 mm) and heavy-duty (typically 2.5 mm) wall thicknesses to match project load requirements.

Strut Channel 41×21 mm is a shallow-profile channel support member within the 41 mm strut family. It shares the same 41 mm mounting width as standard 41×41 mm strut, enabling full accessory interchangeability while offering a lower profile for space-critical applications.

Typical profile dimensions (indicative):

• Product type: Slotted strut channel (channel support system)
• Profile: 41 × 21 mm shallow C-channel with inturned lip edges
• Manufacturing: Cold-formed from low-carbon strip steel
• Standard length: 3000 mm / 6000 mm (custom cut lengths available)
• Material options: Mild steel, stainless steel (SS304 / SS316L), aluminum
• Wall thickness: 1.1 mm to 3.0 mm available
• Slot pattern: Continuous slotted holes along one face (slotted variants)
• Surface finish: Pre-galvanized (PG), hot-dip galvanized (HDG), powder coated
• Accessory compatibility: Standard 41 mm strut nuts, brackets, and fixings
• Customization: Custom lengths, materials, finishes, and slot configurations available upon request

Different finishes are available for various environments.

• BS 6946 (channel support systems)
• GB/T 23639-2017, JB/T 10216-2013 (cable support system reference)
• Compatible with IEC 61537 cable tray/ladder systems when used as the support structure

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. Brackets, channel nuts, and accessories lock into the inturned lips, creating secure, adjustable connections at any point along the channel without welding.

The 41×21 mm profile—often referred to as half-strut or shallow strut—is the lower-depth member of the 41 mm strut family. It provides the same 41 mm accessory interface as 41×41 mm standard strut but with reduced section depth, making it the preferred choice when:

• Ceiling void depth is limited
• Wall-mounted supports must sit close to the surface
• Light-duty cable containment, conduit, or pipe support is required
• A compact trapeze or hanger assembly is needed

In cable management applications, strut channel acts as the structural support framework from which cable trays, cable ladders, mesh trays, and conduit systems are suspended or wall-mounted—typically using threaded rod, trapeze brackets, or direct channel fixings. Strut systems are classified under channel support standards (BS 6946), while the cable trays and ladders they carry are governed by cable management standards such as IEC 61537.

Chinne Electric 41×21 mm strut channels are supplied in slotted and plain configurations, with material and finish options selected to match indoor, outdoor, and corrosive-environment project requirements.
