Light weight purlins for roofs

Lightweight purlin systems make building construction fast and easy, allowing you to build the envelope and roof structures with little effort. 

Ruukki has a wide selection of purlins, which are suitable for both insulated and uninsulated roofs and walls. You can choose an alternative that best suits your needs, depending on the required span length and the loads. The benefits of using purlins are:

  • Light weight
  • High-strength properties increase efficiency
  • Efficient logistics
  • Good corrosion resistance
  • Can be used also in demanding conditions
  • Fully recyclable

The lightweight purlin design is always project-specific. Use our design tool PurCalc to optimize the wall or roof structure.

PurCalc® software for designing purlins

With the PurCalc® software, the user can design roof and wall purlins produced by Ruukki. The purlins are designed as continuous beams. The purlin type must be the same for the whole structure, but the thickness may vary. One of the purlin flanges is assumed to be supported with the profile sheet. The other flange may be either supported or unsupported. Basic loads such as uniform snow load and wind load can be easily given with a few parameters. Also, more complicated load types, such as snowdrift loads, can be given. The software calculates the necessary fasteners for the supporting structure as well.

Load-bearing sheets

Load-bearing sheets are a cost-effective roof solution for achieving long spans, which eliminates secondary steelwork. They may also be designed as a stressed skin to distribute horizontal loads to the frame/foundations.
