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

TH C-Purlin FAQ
It supports roof or wall cladding and transfers loading to the main structural frame as a secondary member.
Yes. The galvanised coating offers strong corrosion protection when specified correctly for the exposure environment.
Selection depends on span, spacing, load and wind pressures. Refer to span tables and confirm with the project engineer or supplier.
