Excerpt:
Cold-formed slotted channel for coordinated pipe supports, cable supports and service-installation frames. Define section geometry, slot layout, compatible fittings and coating as a system. Load capacity depends on span, orientation, joints and the full support arrangement; a channel size alone is not a safe-load rating.

Galvanized Slotted C Strut Channel
Cold-formed slotted channel for coordinated pipe supports, cable supports and service-installation frames. Define section geometry, slot layout, compatible fittings and coating as a system. Load capacity depends on span, orientation, joints and the full support arrangement; a channel size alone is not a safe-load rating.
| Ordering item | Specification |
|---|---|
| Material / standard | EN 10025-2 base steel reference / formed profile to approved drawing |
| Product family | Channels |
| Supply basis | Enquiry-based grade, dimensions, processing and quantity; availability, MOQ and delivery confirmed in the quotation. |
| Inspection documents | Request heat/batch records and EN 10204 3.1 or other documents where required; actual document scope must be confirmed. |
01 / Selection Advantages
- Repeated slots allow adjustable assembly when used with compatible specified fittings.
- Drawing-based review aligns channel, nuts, brackets and anchorage interfaces.
- Pre-agreed cut lengths and bundle identification can simplify site sorting.
02 / Specifications & Size Schedule
Use the following options to prepare a complete enquiry. The lists do not imply that every dimension combination is stocked or interchangeable with another standard. State the required tolerances and quantity for each line.
| Parameter | Enquiry requirement |
|---|---|
| Profile / mm | 41 × 21 or 41 × 41 enquiry series |
| Base thickness / mm | 1.5, 2.0, 2.5 enquiry options |
| Length / mm | 3000, 6000 or agreed cut lengths |
| Slots | Width, length, pitch, end offset and orientation from approved drawing |
| Coating | Pre-galvanized or after-fabrication hot dip; state route and standard |
| System design | Project engineer to approve allowable loads, span, connections and anchors |
| Profile H × B / mm | Thickness enquiry / mm | Define together |
|---|---|---|
| 21 × 41 | 1.5, 2.0 | Slot pattern, return lips and matching nuts |
| 41 × 41 | 1.5, 2.0, 2.5 | Span/load case and connector arrangement |
| Back-to-back option | By drawing | Joint method and combined section testing |
03 / Chemical Composition
Composition is expressed in weight percent. Maximum and minimum limits refer to the listed grade/product reference; final acceptance follows the agreed standard edition and heat analysis.
| Element | Grade reference / wt.% |
|---|---|
| C | ≤0.17 at t ≤16 mm |
| Mn | ≤1.40 |
| P | ≤0.035 |
| S | ≤0.035 |
| N | ≤0.012; deoxidation provisions apply |
| Cu | ≤0.55 |
| Si | No fixed limit in this grade table |
| Fe | Balance |
04 / Mechanical Properties & Technical Notes
| Base material | Min yield / MPa | Tensile / MPa | Important distinction |
|---|---|---|---|
| S235JR, t ≤16 mm reference | 235 | 360–510 | Base-steel properties do not constitute a channel load test |
The quoted S235JR composition and strength describe the base steel. Forming, perforation and assembly must be considered in the finished support design. The 41-series geometry reference is for selection only and does not imply compatibility, certification or affiliation with any branded support system.
05 / Processing & Inspection
| Control point | What to agree or inspect |
|---|---|
| Drawing review | Verify profile, lip, slot pattern, hole burrs and end clearance. |
| Geometry | Measure section height/width, thickness, slot dimensions and straightness. |
| Coating | Agree coating route, thickness/class and cut-edge treatment. |
| Compatibility | Check sample fit with specified nuts/brackets; obtain project load approval. |
Include additional tests, third-party inspection, marking transfer and processing requirements before order confirmation. Qida can coordinate the agreed inspection scope and supporting records; an online product guide is not a delivered-batch test certificate.
06 / Export Packaging & Transport
| Packing item | Practical requirement |
|---|---|
| Size segregation | Bundle sections by size/grade/length and transfer clear heat/order labels. |
| Protection | Use suitable spacers, strap guards and dry supports; separate finished faces. |
| Handling | Agree bundle weight, sling positions and access for the destination equipment. |
| Loading plan | Support long sections, distribute mass and secure against sliding and tipping. |
Agree destination port, Incoterms rule and named place, package mass, unloading equipment and required shipping documents. Container capacity depends on payload limits, route and load distribution. For regulated solid-wood packaging, confirm the applicable ISPM 15 treatment and marking requirements.
07 / Qida Procurement Support
| Order stage | Our coordination | Buyer benefit |
|---|---|---|
| Specification review | Review material, dimensions, units, drawings and destination requirements. | A clear line-by-line enquiry helps reduce omissions and incompatible substitutions. |
| Processing plan | Confirm cutting, finishing, inspection and identification items in writing. | The buyer can assess scope and acceptance before production or sourcing proceeds. |
| Packing & dispatch | Coordinate labels, packing list, suitable protection and shipping-document requirements. | Piece count and heat/lot correspondence can be checked at agreed milestones. |
| After-sales follow-up | Review order references, arrival photos and inspection records for reported issues. | A documented issue description supports a specific response and follow-up. |
08 / Request a Detailed Quotation
Send the standard and edition, grade, size schedule, quantity per size, material condition, finish, processing drawings, tests/documents, packing requirements and destination port. Include maximum piece or package weight and any project approval requirements. Pricing, minimum quantity and lead time will be confirmed against the actual requirement.
