High-quality purlins, girts, and eave struts designed to support wall and roof cladding while transferring applied loads securely to the primary structural frame.
Secondary framing members support the roof and wall cladding and transfer the applied loads to the primary structural frame. The main components include roof purlins, wall girts and eave struts, providing structural stability and efficient load distribution.
Roof purlins are cold-formed Z-sections, typically 200–250 mm deep and manufactured from 1.6–3.0 mm thick steel. They support the roof sheeting and transfer loads to the primary rafters.
Purlins are connected to the top flange of the rafters using bolted clips, with the purlin web bolted to the clips. At frame locations, the purlins are overlapped to provide continuous beam action, improving structural efficiency and stability.
Wall girts are cold-formed Z-sections, typically 200–250 mm deep and manufactured from 1.6–3.0 mm thick steel. They support the wall cladding and transfer wind loads to the primary columns.
Girts are connected to the outer flange of the side-wall columns using bolted clips, with the girt web bolted to the clips. Their ends are overlapped at column locations to provide continuous beam action, improving structural efficiency and stability.
Eave struts are cold-formed C-sections, typically 200–250 mm deep and 2–3 mm thick. They are connected to the outer flange of sidewall columns using bolted clips, with the eave strut flange bolted to the clips.
