Purlins are galvanised steel beams that allow you to safely attach roof and wall cladding sheets to any building. The combination of our Z purlins and C section purlins provides a strong and sturdy complete structural solution ready for roofing and side cladding.
C SECTION PURLINS

C Section Purlins are designed to form the walls and floor joists of a building shell structure and are ideal for support beams for mezzanine flooring.
They can also be used for door framing, roof trimming, window trimming, parapet rails and side rails.
Z PURLINS

Z Purlins are designed to form the roof and wall joists of a building shell structure.
They sit between the steel sheets and the building, acting as a support for the sheets to ensure it is firmly attached and safely in place.
