What is a Steel Purlin?

Steel Purlins are essential cold-formed structural elements serving as longitudinal beams that connect trusses or rafters in roofing systems. Manufactured in various sizes, these purlins effectively transfer external loads, such as gravity and wind, from the roof to the top chord of the truss. The design of purlins is based on a pin-connected structure, where the spacing between trusses represents the span and the ends act as joints. To counteract sagging caused by applied loads, sag rods are strategically installed for added lateral support.

In addition to their primary roofing application, Steel Purlins are also utilized as girts for wall cladding, making them a versatile choice for construction projects. As a leading supplier in China, we offer high-quality steel purlins from our advanced factory, ensuring reliable performance and durability. The image below demonstrates a typical steel framing system featuring purlins, highlighting their crucial role in structural integrity.
