Steel Roof Purlins & Beams

Steel purlins are structural support sections used to carry roofing sheets, side cladding and associated building loads across steel-framed, agricultural, commercial and industrial structures.

Our range includes galvanised Zed purlins, Cee purlins, mezzanine purlins and Sigma eaves beams, giving installers and contractors options for different roof layouts, wall systems, span requirements and fixing arrangements.

Zed purlins are commonly used in roof and side rail applications where continuous support is needed across multiple bays, while Cee purlins are often chosen for simpler framing layouts, end supports and general-purpose structural use.

Mezzanine purlins are designed for raised floor and mezzanine structures, where additional steel support is needed beneath decking or floor build-ups. Sigma eaves beams are used at the eaves of a building, helping to form the junction between roof structure, wall cladding and gutter line.

These steel purlins and beams are suited to projects where timber battens aren't appropriate for the scale, load or frame type of the building.

They're typically used with metal roofing sheets, box profile cladding, industrial roof systems, agricultural buildings, workshops, storage units and steel-framed outbuildings.

The correct purlin type, size and spacing should always be selected according to the building design, loading requirements, fixing method and any relevant structural calculations.
