Providing the structural backbone for your roof envelope with our high-strength galvanised steel purlins. Fabricated in Somerset for maximum structural efficiency, we specialise in sleeved multi-span systems that offer superior load-bearing performance for large scale agricultural and industrial roofs.
Sleeved System Experts: We specialise in sleeved purlin configurations, allowing for continuous spans across multiple rafters. This provides a stiffer, more efficient roof structure compared to traditional butted systems.
In-House Steel Fabrication: We manufacture Z and C sections in both 6mm and 2mm thick galvanised steel, providing the structural integrity needed for everything from domestic workshops to heavy-duty industrial units.
Trade-Ready Punched Cleats: Our 6mm heavy-duty cleats come pre-punched with 18mm diameter holes, ensuring a fast, precision-fit connection to your rafters without the need for on-site drilling.
Z-Purlin & C-Section Specialists: Specifically designed for lapped and sleeved systems, allowing sections to nest together for maximum strength.
Complete Purlin Kits: From the main structural sections to matching purlin sleeves and weld-on or bolt-on cleats, we provide the full structural package for a seamless build.
Structural Timber Purlins: For traditional builds, we stock high-quality C16 CE-Treated Timber Purlins (up to 8x3"), delivering structural durability for lighter-weight roofing projects.
Direct Trade Support: Our experienced Somerset team is on hand to discuss your specific measurements and supply the exact sections your engineer specifies.
