Z AND C Cold Rolled Formed Section – Purlin & Girt

Alfa Enterprises offers Cold Rolled Formed Sections for buildings. Purlins, girts and eave struts are secondary structural members used to support the wall and roof panels. Purlins are used on the roof, girts are used on the walls and eave struts at the intersection of the sidewall and the roof. Secondary members have two other functions: they act as struts that help in resisting part of the longitudinal loads that are applied on the building such as wind and earthquake loads, and they provide lateral bracing to the compression flanges of the main frame members thereby increasing frame capacity. Purlins, girts and cave struts are designed in accordance of the American Iron and Steel Institute (AISI), “Cold-formed steel design manual”. Purlins, girts and eave struts are available in two standard surface finishes, i.e., MS and galvanised, and three standard thicknesses. Galvanised finish can be made available upon request and subject to extended delivery. Galvanised finish for secondary members is available only in thickness ranging from 1.5 mm to 2.0 mm. Roof and wall panels are laid perpendicular to the roof purlins and wall girts, respectively, and fastened to them by means of self drilling fasteners.
