Everything You Need to Know About Purlins

Purlins are among the major parts of the roof. Roof purlins are supported either by rafters or building walls; Purlins are actually horizontal beams that are used for the structural support in a number of buildings. Traditional timber framing includes the three basic purlin types.

Just like C purlins, the Z purlins resemble the alphabet Z and are also called as Zed Purlins. This shape helps Purlins to overlap joint and prove to be stronger and studier than the C purlins.
