Z purlins

Z purlins

Z purlins or zed purlins are horizontal beams that are designed to form the roof and wall joists of a building shell structure (also view our C section purlins page). They sit between the roofing sheets and the building, acting as a support for the sheet to ensure it is firmly attached and safely in place.

Purlins are also known as cold-form, or rolled-form steel. A purlin shed is a structure where the main portal frames are made out of rolled-formed sections, usually C purlins. These purlins are made out of steel sheets that range between 1mm, 2mm or 3mm steel.
