Secondary Structural Members include roof purlins, wall girts, eave struts, C / Z Sections, flange braces, gable angles and base angles. Purlins, Girts, Eave Struts and C‐Sections (used as base channels and as door jambs & headers in framed openings of double sliding doors) are rolled formed from 345 mm wide galvanized coils in thickness of 1.5, 1.75, 2, 2.25 and 2.5 mm.
Z & C Purlins have replaced the conventional tubes and angles used earlier in roofing. Purlins are fast gaining recognition in Pakistan due to their accuracy and wide range of applicability in various styles of roofing and side cladding. These are capable of meeting the needs of various establishments requiring large sized roofing such as Railway Platforms, Workshops, Factory Sheds, Warehouses and other Industrial Sheds
