Light beams for girts and purlins

It is smart to use Borga’s light beam as a bearing element when building roof and wall structures. Another advantage is that light beams make it possible to achieve straight lines when installing wall sheets, which makes the building more attractive.

The light beams are available as standardised Z and C profiles, or as special profiles manufactured according to your wishes. Pre-punched holes provide the potential for precise, rapid assembly.

Buying light beams from Borga entails:
  • A good value, durable solution
  • Customised lengths
  • Simple assembly with pre-punched holes
  • Fast delivery

borga_building_components_lightbeams_zThe Z profile can be used both as a purlin and a girt. The profile has been specially developed for assembly with overlaps, in double sections. In the case of loads where only one of the flanges is stabilised, Z profiles are used almost exclusively.borga_building_components_lightbeams_c

 

The C profile is normally used as a girt or when overlaps are not required. The profile also works well when terminating against windows and doors etc.
