Purlins support the deck of the roof so they can withstand weight and weather elements. Overall, purlins are used in several types of structures that require roof frames, whether for commercial agricultural of residential. Purlins are horizontal spares that supported by struts. The purpose of purlins is to provide intermediate support of the roof structure. The struts transfer load from the struts to either a load-bearing wall or a specially designed joist.

Purlin function: Three structural functions are provided by metal roofing purlins. Firstly, the roof is protected by the purlins. Second, purlins tie the rafters together, stabilizing and reinforcing the rigid framing of the frame. And the third, between the spans of the individual framing bays, purlins provide additional support.

We can supply both type of Purlin “C” & “Z” of GI & MS.
