Strut Channel (C Channel)
41 mm metal-framing channel for trapeze hangers, wall brackets and support frames
The 41 mm metal-framing channel that carries the tray runs — trapeze hangers, wall brackets and support frames for cable tray, pipework and equipment. Our catalog C-channel range covers 41×21 and 41×41 single profiles plus welded back-to-back doubles, in slotted and plain versions, with the brackets, hanging supports and spring-nut fittings of the same support system.
1 / 2Technical Drawings & Dimensions
Schematic diagrams below show the single C profile and the back-to-back double, and the parameters that define a profile. They are schematics only — not to scale, not engineering drawings, and not CAD drawings. Do not use them as fabrication drawings; model-specific dimensions are cited from the catalog table in your quotation.
Verified parameters
| Profiles | 41×21 mm (C 2141) · 41×41 mm (C 4141) · welded doubles 42×41 mm (C 4241) & 83×41 mm (C 8341) |
|---|---|
| Versions | Slotted (A) · plain · 3-side perforated (C 4141B, 41×41 only) |
| Slot size | 14×25 mm at 50 mm pitch (slotted versions) |
| Thickness | 1.2–2.5 mm by profile — 41×21 from 1.2 mm · 41×41 in 1.5 / 2.0 / 2.5 mm · doubles in 2.0 / 2.5 mm |
| Lengths | 3,000 mm standard · 6,000 mm in hot-dip galvanized |
| Weight | 0.85–5.50 kg/m by profile & thickness — e.g. C 4141A at 1.55–2.58 kg/m |
| Allowable bending stress | 21.82 kN/cm² (published per profile in the catalog, with moment of inertia and section modulus) |
Spring channel nuts grip the inturned, serrated edges and fit the slot — fittings can be placed anywhere along the slot and repositioned without drilling.
Configure Your Cable Tray
Pick a style, material and finish — the configurator only offers combinations the published data supports, and your selection is written into the inquiry form at the bottom of the page (you can still edit it there).
Need a Custom Size?
Channels are bundled and strapped in standard lengths; brackets, spring nuts, threaded rods and fittings are counted into the same shipment as your trays, so the support kit lands together with the run it carries. Custom sizes are made to order and confirmed in your quotation — send your BOQ or drawings with the inquiry below (PDF, Excel, DWG or ZIP).

Profile, version, slot, thickness, length, finish and weight ranges from the Hongfeng product catalog. Span safe loads are catalog p.125 (detailed tables below); section data is published per profile in the catalog and is stated here as text only, not tabulated per profile.
Load Data & Installation Conditions
Support selection is a load decision too. The catalog safe-load tables below (p.125) give, for each profile and thickness, the uniform load q and the concentrated allowable load F at spans from 500 to 3000 mm, at a maximum deflection of L/200. Spans the catalog leaves blank have no published value — they are confirmed with your quotation, never interpolated. The catalog does not state whether q is per metre or total, or a safety factor beyond the deflection limit, so the quotation will state the table used.
Span safe-load tables are catalog p.125, published as two separate tables: uniform load q and concentrated allowable load F — do not mix the two. Maximum deflection L/200. Spans the catalog leaves blank have no published value and are confirmed with your quotation, never interpolated. The catalog does not state whether q is per metre or total, so the quotation will state the table used.
Available Configurations
- 41 mm framing system: 41×21 and 41×41 single channels, plus welded doubles 42×41 and 83×41 for heavier trapeze and frame loads
- Slotted versions punched with 14×25 mm slots at 50 mm pitch; plain and 3-side perforated versions in the same profile family
- Spring channel nuts grip the inturned, serrated edges — fittings can be placed anywhere along the slot and repositioned without drilling (catalog: Metal Framing – 41 mm)
- Safe loads published by span in the catalog (p.125) at a maximum deflection of L/200 — pick profile, thickness and span, then read q or F off the table
Profiles — C channel
This grid lists profile section sizes only (width × height) — it carries no SWL or weight values. For safe loads by span, read the detailed tables below (catalog p.125, maximum deflection L/200). Filter by profile, width and height — the configurator selection filters this table automatically.
| Style | Width (mm) | Height (mm) | SWL (N/m) | Weight (kg/m) |

This profile grid lists section sizes only — safe loads by span are in the detailed tables below (catalog p.125, maximum deflection L/200). SWL and unit weight for your profile, thickness and span are confirmed with your quotation.
Safe-load tables — by span
Catalog safe loads at a maximum deflection of L/200, where L is the support spacing (span). Blank cells are spans the catalog leaves unpublished — they are left blank, never interpolated. Use the uniform-load table for distributed loads and the concentrated-load table for a mid-span point load; do not mix the two.

Frequently Asked Questions
How much can a strut channel carry?
Read it off catalog p.125: pick the profile (21×41 / 42×41 / 41×41 / 83×41) and thickness (1.5 / 2.0 / 2.5 mm), then read q (uniform load) or F (concentrated load) at your support spacing L, at a maximum deflection of L/200. Spans the catalog leaves blank are confirmed with your quotation.
What is the difference between q and F?
q is the uniform (distributed) load and F is the concentrated allowable load — the catalog publishes them as two separate tables. Select from the table that matches how the load actually acts; do not mix the two.
Slotted or plain — which do I choose?
Slotted versions are punched with 14×25 mm slots at 50 mm pitch and take spring nuts at any position along the slot. Plain and 3-side perforated (C 4141B, 41×41 only) versions are in the same profile family; exact supply is confirmed with your quotation.
What about MOQ, lengths and finishes?
Standard length 3000 mm, 6000 mm in hot-dip galvanized; finishes pre-galvanized / hot-dip galvanized. MOQ is confirmed with your quotation.
What information is required for a quotation?
Profile, thickness, finish, span and quantity — plus the project environment if finish selection matters. Use the configurator above and the inquiry form sends your selection automatically.
Can I submit a BOQ or technical drawing?
Yes — attach PDF, Excel, DWG or ZIP in the inquiry form below, or email the file to jasonzuo@cabletraysystem.com if the upload fails.
What affects the production lead time?
Size, material, finish, quantity and current production scheduling. Lead time is confirmed with your quotation — it is not fixed on this page.
