Purlins & Sections for every project
Our range of cold rolled purlins and structural sections provides a versatile and efficient solution for secondary steelwork within modern steel framed buildings. The system includes a comprehensive selection of Z sections, C sections, Sigma sections and Eaves Beams, allowing designers and contractors to create practical and economical roof and wall support systems for a wide variety of building types.
Each section is designed to work as part of a complete system, with dedicated intermediate supports, cleats and connection options available to suit different structural arrangements and loading requirements. This flexibility allows the system to be adapted for both roof purlin and wall rail applications across agricultural, industrial and commercial projects.
With multiple section sizes, thicknesses and connection configurations available, the range offers a high degree of design flexibility while maintaining efficient structural performance. Whether used for simple single-span buildings or more complex multi-span frames, these cold rolled sections provide reliable support for roof and wall cladding systems while helping to optimise material use and installation efficiency.

TECHNICAL: Information
Our range of cold rolled purlins and structural sections are designed to provide reliable and efficient secondary steelwork for a wide range of building types. Manufactured from high-strength steel, these sections are commonly used as roof purlins, wall rails and eaves beams within steel framed buildings.
To support design and specification, we provide comprehensive load/span tables covering the various connection types, along with detailed DWG drawings and a full technical manual for our section range.
Our systems are also fully specifiable within Tekla and Autodesk Advance Steel, allowing designers and contractors to easily incorporate the sections into their structural models and project drawings.
In addition, our team can assist with the layout and configuration of purlin, rail and eaves beam systems, helping to develop practical and efficient arrangements using CAD support. This assistance is intended to support project development and coordination alongside the appointed project designers and engineers.
MAIN FEATURES
- Ideal for use as roof purlins and wall rails in steel framed buildings
- Multiple versatile connection system available including sleeved, butted and double span
- Excellent strength-to-weight ratio for economical secondary steelwork
- Suitable for multi-span roof systems
- Available in a range of depths and thicknesses
Our purlins and structural sections are manufactured from high-strength steel with a minimum yield strength of 450 N/mm², providing increased structural capacity compared with systems produced from lower grade steels such as 390 N/mm². The higher strength material allows the sections to deliver excellent load carrying performance while maintaining an efficient strength-to-weight ratio.
All sections are supplied with a Z275 galvanised coating, providing durable corrosion protection suitable for a wide range of construction environments. This coating applies approximately 275 g/m² of zinc to the steel surface, helping to extend service life by protecting the underlying steel from moisture and atmospheric exposure.
The combination of high-strength steel and robust galvanised protection ensures our purlins and sections offer reliable structural performance, durability and long-term resistance to corrosion, making them well suited to agricultural, industrial and commercial building applications.
Thomas Panels and Profiles offer a versatile range of purlin and rail layouts designed to suit various structural needs, including butted, sleeved, and double-span configurations. Each layout is engineered for optimal performance and ease of installation, providing robust support for cladding systems.
