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.

Strong TH C-Section system for framing and roofing

The TH C-Section C-Channel is purpose-designed for the TH-Truss^® system, providing a rigid yet lightweight framing solution. Its stiffened C-profile improves bending performance and limits deflection, making it suitable for long-span roofs and light commercial or residential applications.

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.
