Notes

  • The wedge seated frame has been designed to suit all existing gully pot styles and will sit over a typical Ø 450mm circular or horseshoe chamber opening. The frame flange has reduced apertures as a mortar guard to stop backfill material from entering the chamber.
  • The use of Armadillo is recommended where exposure to construction site traffic is likely. 
  • The D400 load capability of these Group 3 products also offers the benefit of making them suitable for exposure to Group 4 traffic types. Where 3-flange D400 Gully Grate assemblies are employed, we recommend that they are installed against a kerb, not in an open highway location. All values stated are nominal within 2.5% tolerance.

The Sea Starts Here

We've taken a notable step in environmental advocacy by updating our most popular Tristar gully gratings to include the phrase "The Sea Starts Here". This initiative aims to highlight the critical issue of water pollution among communities and the wider industry. The message serves as a poignant reminder that our actions on land reverberate through to our oceans, urging us to consider how we dispose of waste and the long-term effects on marine ecosystems.
