Our standard range of GRP gratings are all non-conductive. Conductive grating has a secondarily applied conductive surface which, when properly grounded with copper earthing straps, drains off the build-up of unwanted, potentially dangerous static electricity. This highly specialised grating produces an electrical resistance of less than 26 kilo ohms per 300mm, while the grating retains all of the other desirable characteristics of conventional glass reinforced plastic (GRP) grating. It is typically used on roof walkways of high buildings as a defence against lightening strikes and in environments where static sparks could cause problems, such as:

  • High-tech industries where static electricity can damage chips, laser discs etc
  • Facilities where explosive-proof components are specified
  • Dry environments where static sparks can endanger personnel
  • Other high hazard environments, where gases, solids or flammable liquids could be ignited by a static spark

QuartzGrip® Conductive GRP Grating maintains all the benefits of standard fibre glass grating: low-maintenance, lightweight, long-lasting, slip and corrosion-resistance.
