Notes

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.

ID badging and antenna options (RFID, NFC, IoT)

A large number of our Unite and Highway covers provide the facility for a retrofittable badge to be installed in the cover, without the need for welding. In addition, this location can also be used to install communications antennas within the cover, removing the need to adjust the surrounding road surface.

This article discusses the potential applications of this technology.
