Secondary framing systems is mainly purlin and girth of Z or C shapes of Various size. In Pre-engineered building normally cold form Z section are used for secondary framing to achieve high strength and lower weight. Typically cold form members used for roof are called purlin and for wall it is called as girth however prole for the both in general is same. Sometime C section is also used in place of Z. Purlin/Girth are the members which transfer forces and moments from one frame to another frame for overall stability o f the building structure and it all acts framing systems for weather covering sheeting purpose. For all practical purpose these members are spaced at an interval of about 1.5mm; which can vary and placed perpendicular to the direction of the rafter.
