Secondary Framing
Secondary framing consists of elements which support the roof and wall sheeting and transfer load to the primary framing. These include Roof Purlins, Wall Girts, Eave Struts, Clips etc.
ROOF PURLINS Roof purlins are cold formed Z profiles, with depth of 150, 200 or 250 mm and thickness 1.5, 1.75, 2 or 2.5 mm. These are fixed to the top flanges of the rafters by means of clips welded or bolted to the rafters, and the purlin web bolted to the clips. Purlins ends overlap to act as continuous beams.
WALL GIRTS Wall girts are cold formed Z sections, with depth of 150, 200 or 250 mm and thickness 1.5, 1.75, 2 or 2.5 mm. These are fixed to the outer flange of the side wall columns by means of clips welded or bolted to the column and girt web bolted to the clips. Overlap connections are provided for continuous beams.
