Cold Formed C Channel - ASTM Certified Steel Manufacturer
Cold formed C channel is a versatile structural steel section manufactured through precision roll forming or press braking of flat steel coils at ambient temperature. Unlike hot-rolled channels, the cold forming process preserves tighter dimensional tolerances, produces cleaner surface finishes, and achieves enhanced mechanical properties through strain hardening. As a leading steel manufacturer with over 15 years of production experience, we supply premium-grade cold formed C channels to construction firms, solar racking installers, and industrial fabricators across 40+ countries. Our products conform to ASTM A1011, ASTM A572, and EN 10162 standards, ensuring consistent quality for structural framing, curtain wall support systems, cable trays, and purlins in pre-engineered metal buildings.
What Is Cold Formed C Channel?
A cold formed C channel is a structural steel profile with a distinctive C-shaped cross section consisting of a web, two flanges, and optional lip stiffeners. It is produced by progressively bending steel strip or sheet—typically ASTM A36, A572 Grade 50, or galvanized G90 coil—through a series of roll forming dies without applying heat. This cold working process increases the yield strength by approximately 15%–20% over the base material, resulting in a minimum yield strength of 345 MPa (50 ksi) for Grade 50 material and a tensile strength of 450 MPa (65 ksi) minimum. The finished section features sharp corners with inside bend radii as tight as 1.0t–2.0t (where t = material thickness), delivering a high strength-to-weight ratio that reduces overall structural dead load.
Cold Formed C Channel Technical Specifications
Our cold formed C channel product line covers a comprehensive range of dimensions to meet diverse engineering requirements. Below are the key technical parameters:
- Web depth: 75 mm to 300 mm (3″ to 12″)
- Flange width: 35 mm to 100 mm (1.375″ to 4″)
- Material thickness: 1.2 mm to 6.0 mm (18 gauge to 4 gauge)
- Lip depth: 10 mm to 25 mm for lipped configurations
- Standard length: 6,000 mm, 9,000 mm, or 12,000 mm; custom lengths available
- Steel grades: ASTM A36 (Fy = 250 MPa), ASTM A572 Gr.50 (Fy = 345 MPa), S350GD+Z per EN 10346
- Surface treatment: Hot-dip galvanized (Z120–Z275 coating), pre-galvanized, or mill finish
- Dimensional tolerance: Web depth ±1.0 mm, flange width ±0.8 mm per ASTM A1011
- Section properties: Moment of inertia from 28 cm⁴ (C75×35×1.5) up to 1,520 cm⁴ (C300×100×6.0)
All products undergo in-house quality inspection including dimensional verification, tensile coupon testing per ASTM A370, and zinc coating thickness measurement via magnetic induction method. Mill test certificates (MTC) conforming to EN 10204 Type 3.1 are provided with every shipment.
Applications of Cold Formed C Channels in Modern Construction
Cold formed C channels serve critical roles across a wide spectrum of structural and non-structural applications. In pre-engineered metal buildings, they function as roof purlins and wall girts, spanning distances up to 9 meters between primary frames. The solar energy sector relies on galvanized C channels as mounting rails for photovoltaic panel support structures, where the G90 zinc coating (275 g/m² minimum) delivers outstanding anti-corrosion properties for 25+ year service life. Additional applications include mezzanine floor framing, drywall stud partitions, electrical cable tray systems, greenhouse frameworks, and modular storage rack uprights. The lightweight profile—typically 40%–60% lighter than equivalent hot-rolled sections—reduces transportation costs and simplifies on-site handling without sacrificing load-bearing capacity.
