Z Purlin 2"x4"x20' 1.2mm

Z purlins are used in steel framing as the fixing member for the roof sheeting

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.
