C Channel — Modular Strut Channel for Piping, Cable Tray & Duct Support in Industrial Workshops
Qinkai C channels are cold-formed steel strut rails, the modular backbone of industrial workshop support systems — holding pipes, cable trays, ducts and equipment in place, alone or combined in any configuration. Slotted profiles allow infinite along-rail adjustment and tool-free repositioning, ideal for production lines that evolve with the process.
Available in 41×21, 41×41, 41×62 and 41×82 mm series with wall thicknesses 1.5–3.0 mm, in hot-dip galvanized steel (ISO 1461), zinc-aluminum-magnesium or stainless steel. Executed to MSS SP-58 with matching fittings — nuts, pipe clamps, rod hangers and connectors — every bracket position is adjustable without drilling. Factory-direct with load tables and assembly drawings.

Advantages
Six Core Advantages
| Advantage | Value Proposition |
| 1. Infinitely adjustable modularity | Slotted profile fixes at any position along the rail — line retrofits without re-drilling |
| 2. One rail, multiple services | Pipes, cable trays, ducts and equipment share the same track — cleaner workshop, better space utilization |
| 3. Workshop-grade corrosion protection | HDG ≥ 55 µm for oil, humidity and washdown; ZAM / stainless for higher requirements |
| 4. Welding-free installation | Mechanical connection via channel nuts — no hot work, no production downtime during retrofits |
| 5. High-strength cold-formed steel | Q355B saves 15%+ weight — smaller deflection on long-span hangers |
| 6. Deliverable load data | Verified load tables + deflection data shipped with the order — design institutes can verify directly |
Core Competitiveness (Why Qinkai)
Complete one-stop package — channel, nuts, pipe clamps, rod hangers and connectors from one factory with one finish system — single-order procurement for workshop projects.
Deliverable load data (hard qualification) — verified load tables and deflection data for every series, ready for workshop construction drawings and acceptance files.
Three-tier corrosion selection — HDG (standard workshops) / ZAM (high humidity, high corrosion) / stainless (food & chemical plants) — recommended by working conditions, right the first time.
Synchronized with trays & seismic supports from the same factory — C channel as the base rail completes the full workshop support system with cable trays, brackets and seismic bracing — one supply source.
Factory-direct, integrated manufacturer — own cold-forming and galvanizing lines; non-standard lengths and cutouts quoted within 24 h; controlled lead times.
Applications
An industrial workshop is the most service-dense space in any facility: process piping, cable trays, ducts and compressed-air lines crisscross within limited headroom. C channel as the modular support base rail gives every service line an independent, adjustable, expandable support point — when the line changes, only the bracket moves, never the structure.
| Application | Key Value |
| Process Piping Support | Water, gas and hydraulic lines run along the rail; slot positions fine-adjust at any point |
| Cable Tray Support | Same-rail integration with trays and brackets — one integrated cable routing system |
| Duct Hanging | 41×62/82 heavy series for long-span hangers — controlled deflection |
| Equipment Framing | Modular platforms, equipment bases, guard rails and maintenance access |
| Assembly Line Routing | Supports move with the line — fast relocation without drilling |
| Compressed Air & Fire Branch Piping | One unified support system — clean workshop visual, clear maintenance access |
Application block copy: From process piping to cable trays and ventilation ducts, Qinkai C channels support every service in the workshop on one modular system — adjust, extend and relocate without drilling, welding or production downtime.
FAQ
Q1: How much load can it carry?
A1: 250–650 kg/m hanging capacity by series and wall thickness (indicative); verified load tables and deflection data ship with every series.
Q2: Will it rust in workshop oil/humidity?
A2: Standard workshops use HDG ≥ 55 µm; high-humidity / high-corrosion workshops use ZAM; food and chemical plants use stainless — recommended by working conditions.
Q3: How does it integrate with cable trays and piping?
A3: The channel is the support base — pipe clamps for piping, brackets for cable trays, rod hangers for ducts; multiple fittings plug into the same rail.
Q4: Slotted or toothed?
A4: Slotted for general fixing and fine adjustment; toothed (internal teeth) for high-vibration applications requiring slip resistance.
Q5: Can you customize length / cutouts? MOQ?
A5: Yes — length, cutouts and finish all customizable; quote within 24 h of your drawing; MOQ from 100 m per size.
Q6: Is field welding required?
A6: No — fully mechanical connection (channel nuts / connectors), no hot work; production continues during retrofits.
