Manufactured to meet rigorous EN 10025 and EN 10034 standards, our mill-direct supply chain eliminates unnecessary intermediaries, delivering certified product at cost-effective rates with full traceability documentation. Whether you are sourcing for large-scale infrastructure projects, mechanical frameworks, or modular building systems, our steel channel profiles offer the dimensional precision and mechanical consistency that demanding applications require. Each batch undergoes strict chemical composition verification and mechanical testing, ensuring compliance with European normative requirements before dispatch. With production capacities capable of fulfilling both spot orders and long-term supply contracts, we serve steel distributors, structural fabricators, and EPC contractors across more than 40 countries. Our logistics network supports FCL and LCL shipments, with lead times optimized through strategically positioned mill partnerships across Europe and Asia.
What is Steel Channel Profile?
A steel channel profile — commonly referred to as a C-channel or U-channel — is a hot-rolled or cold-formed structural steel section characterized by a web and two parallel flanges projecting at right angles. Available in standard UPN (parallel flange) and UPE (equal flange) configurations, it finds extensive application in structural frameworks, crane rails, cable trays, and load-bearing supports across construction, shipbuilding, and mechanical engineering sectors.
Steel Channel Profile Technical Specifications
Our steel channel profiles are produced from S235JR, S275JR, and S355JR grade steels, delivering yield strengths ranging from 235 MPa to 355 MPa and tensile strengths between 360 MPa and 630 MPa per EN 10025-2. Standard section heights range from 30 mm to 400 mm, with web thicknesses from 3.0 mm to 15.0 mm. Material density is 7.85 g/cm³ at 20°C, and surface condition conforms to EN 10163-3 Class C, Subclass 1. Mill test certificates (EN 10204 3.1) are provided as standard with every shipment.
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Standard |
|---|---|---|---|
| S235JR | ≥ 235 | 360 – 510 | EN 10025-2 |
| S275JR | ≥ 275 | 430 – 580 | EN 10025-2 |
| S355JR | ≥ 355 | 470 – 630 | EN 10025-2 |
