SECONDRY FRAMING SYSTEM
Secondary members are load carrying members suitable to ensure the stability of the building against forces in any direction. They primarily include purlins and girts, eave strut, cable bracing and open steel web joists.
Purlins and Girts are Secondary Framing members used to support roof and walls panels. In addition to supporting sheeting/cladding systems, secondary framing also provide lateral bracing to main framing components and hence increasing their load carrying capacity.
These materials are available in different thicknesses and are made from high grade pre-galvanized coils using cold roll forming technique.
