Our C and Z sections can be supplied with customized profiles, thicknesses, lengths, hole patterns and surface finishes. Pre-punched connection holes and clearly marked components help reduce on-site processing and improve installation efficiency.
From individual purlin orders to complete secondary framing packages, we provide factory-direct manufacturing for warehouses, industrial plants, logistics centers, agricultural buildings and prefabricated steel projects.

C sections have a uniform channel-shaped profile and are widely used for simple-span roofing, wall girts, door frames and secondary structural supports. Their symmetrical shape makes positioning and connection convenient.
Z sections feature an offset profile that allows adjacent members to overlap above the primary frame. This lapping arrangement improves structural continuity and makes Z purlins suitable for multi-span roofing systems.
Installed horizontally between primary roof frames to support roofing sheets, insulation and other roof-system components.
Installed between steel columns to support exterior wall panels and transfer wall loads to the main structural frame.
Special profiles, hole layouts, end cuts, reinforcing plates and connection details can be manufactured according to approved drawings.
