TH C-Section – TH-Truss® C-Channel
TH C-Section is the cold-formed TH-Truss® C-Channel used as a primary framing member in light steel roof and wall systems. Its optimised C-profile delivers reliable bending strength, stable support for roof sheeting and ceilings, and excellent structural efficiency.
- Patented TH-Truss® C-Channel profile for framing and roofing.
- High-tensile galvanised steel for strength and corrosion resistance.
- Cold-formed for consistent sectional accuracy and better load control.
- Designed to integrate with the TH-Truss® steel framing system.

Lightweight and flexible system capacity
TH C-Section is configured within the TH-Truss® design to safely carry roof, ceiling and wind loads for a wide range of building types while remaining light and easy to handle.
- Lightweight & flexible: Simplifies transportation, lifting and on-site assembly.
- Excellent corrosion resistance: Galvanised finish supports long service life.
- Easy workability: Compatible with TH-Truss® connectors and accessories.
Parts of TH C-Section
The TH C-Section geometry is engineered for efficient load transfer and stable fixing within the TH-Truss® framing system. Each element contributes to bending capacity, torsional resistance and ease of installation.
- Web (Depth, D): Main vertical face carrying bending and axial forces.
- Flange (Width, F): Side flanges supporting roof sheeting and ceiling components.
- Lip / Return: Rolled edge that stiffens the flange and enhances torsional stability.
- Base width: Internal width sized to suit TH-Truss® brackets and connectors.
- Thickness (t): Selected according to span, loading and design requirements.
