TH C-Purlin (Galvanised Steel)
TH C-Purlin is a cold-formed galvanised steel C-section engineered for light steel roof and wall framing. Its profile provides reliable bending strength and stable support for cladding while keeping the system efficient and lightweight.
- Enhanced structural performance through innovative cold-forming.
- High-tensile steel composition for dependable strength.
- Advanced cold roll forming for consistent accuracy.
- Pre-punched holes for faster installation.
Enhanced structural performance with innovative cold forming technology
TH C-Purlin is produced using advanced cold roll forming to achieve a precise, stiffened C-profile. This method improves load performance and bending resistance, giving strong structural behaviour without unnecessary weight.
Maximum load-bearing capacity
Built to perform under typical roof and wall loads, TH C-Purlin delivers stable spanning and dependable load transfer for light steel construction.
- Ideal for heavy rainfall: The rib design ensures excellent water-discharge capacity, making it ideal for areas with heavy rainfall.
- Suits any building: TH C-Purlins are adaptable for commercial, industrial, and residential projects, providing flexibility in design and application.
Parts of TH C-Purlin
The C-section geometry is designed for efficient load transfer and stable fixing. Key parts are referenced in the sectional profile.
- Web (Depth, D): Main vertical face that carries bending loads.
- Flange (Width, L): Side plates that increase stiffness and provide fixing surfaces.
- Lip / Return: Edge fold that improves torsional resistance and stability.
- Base width (B): Internal width for connection detailing and alignment.
- Thickness (t): Selected to match span and design loads.
