Purlins are horizontal structural members that provide essential structural support within a roof structure. Positioned perpendicular to rafters or roof trusses, purlins support roofing panels, distribute loads and strengthen the overall structure by transferring weight to beams and columns.
Lynnform supplies steel purlins manufactured from galvanised steel, offering greater durability and fire resistance than traditional timber alternatives. Our range includes Z purlins, C purlins and roof purlins designed for a wide variety of construction projects. Every product is available in different length options and kept in stock ready for quick delivery.
Selecting the right materials helps create a complete roofing system with long life and dependable performance.
Purlins provide intermediate structural support between rafters or trusses, helping prevent roofing panels from sagging or buckling under load. They carry both the dead weight of the roof and additional live loads, improving the overall strength and balance of the structure.
Purlins are commonly classified by both material and profile. Steel purlins are typically cold-formed from steel sheets, creating lightweight but exceptionally strong structural components.
Z purlins feature a profile shaped like the letter “Z” and are commonly specified for larger construction projects because they span greater distances and provide excellent structural support for roof and wall systems. C purlins use a C section profile and are ideal for small to medium-sized projects where reliable support is required. C section members also perform well as support beams and within mezzanine floor joists.
Unlike timber or wood products, galvanised steel purlins resist moisture, provide improved durability and require very little maintenance throughout their service life. Timber remains common in traditional construction, although it requires protection from insects and moisture.
Lynnform supplies purlins manufactured to exact measurements where required, together with eaves beams, fixings, accessories and pre-drilled cleats designed for M16 bolts, helping simplify installation and improve build quality.
Rafters form the primary framework of a roof, while purlins are secondary structural members installed across the rafters to support the roof covering. Customers also ask about battens. Battens provide fixing points for roof coverings such as tiles, whereas purlins provide significantly greater structural support for larger roofing systems.
Purlins help distribute loads through the building structure, supporting both roofs and walls. By transferring loads to the main structural frame, they strengthen the roof and play an essential role in many modern construction systems.
The cost of purlins depends on the product type, profile, specifications and required length. Z purlins are commonly available from around £7.20 per metre, while C section purlins vary in price according to their size and application. Our team will help identify the right product, check stock availability and arrange delivery across the UK.
