Joris Ide Sigma Purlins
Cold-rolled sigma-shaped steel sections used as secondary structural members in roof construction.
Sigma purlins are designed to support roof cladding and transfer loads back to the primary steel frame. They are available in a range of section depths, allowing selection based on span, loading and structural requirements across different building types.
- Cold-rolled sigma-shaped steel sections
- Enhanced stiffness for improved load distribution
- Range of section depths for different spans and loads
- Galvanised finish for corrosion resistance
- Suitable for roof purlin and secondary framing use
- Compatible with standard roofing cladding systems
Sigma purlins are used in roof construction to support cladding and transfer loads to the primary steel frame.
The increased stiffness of the section improves performance under load, helping reduce deflection across longer spans or wider structural grids. This makes them suitable where higher structural demand is expected.
They are commonly used in industrial and commercial steel-framed buildings where reliable secondary support is required for roof systems.
