SHI Service Hole I-Joist

Product description

The uniquie SHI (Service Hole I-Joist) reinforcement plate allows large service pipes, ducting and cables to run through an aperture cut through the web of the JJI-Joist.


  • SHI plate reinforces the JJI-Joist at the location of the large aperture, providing additional stiffness and strength.
  • I-Joist manufacturers recommend that large services are only run in certain positions along the joist length. With SHI plates, large services can now be run where previously not possible.
  • Provides a readily available, easy to fix remedial solution for damaged JJI-Joist webs (SHI plates must only be specified where their application has been fully assessed by a suitably qualified design professional).
