Single-span purlins serve as a substructure for the installation of the roof covering. The comparatively simple geometry of SCHRAG purlins allows purlin shoes made from angle profiles to be screwed on. Alternatively, steel fabricators can also weld flat steel directly vertically to the supports. The process described offers advantages compared to other additionally beaded geometries.
Single-span purlins - the economical assembly system
Solution for buildings with few truss bays and low loads
SCHRAG|lite - our free software for planning and dimensioning - provides valuable support for structural analysis tasks. Our customers can also utilise the structural profile values of SCHRAG lightweight profiles. For special dimensions, we can provide your construction project with an experienced and competent team from our SCHRAG|Engineering Services business unit.
Customised solutions for hall support structures
Basically, we differentiate between single-span purlins and coupled purlins during assembly. While coupled purlins are particularly suitable for buildings with many girder bays, large spans and higher loads, the assembly of single-span purlins is a particularly economical option for the construction of hall girder structures, as single-span purlins are predestined as customised solutions for buildings with few girder springs and low loads. They can be installed either suspended above the trusses or between the trusses.
