About

The non-conductive, lightweight properties of GRP fencing make it a highly effective alternative to traditional steel fencing, whilst still maintaining the strength.

It is highly beneficial in areas such as railways, electrical enclosures and chemical sites.

GRP Pales independently tested & comply with the requirements of BS 1722-12:2016 for General Purpose Fences & comply with BS EN 13706, either E17 or E23

  • GRP boundary fencing
  • GRP trackside fencing
  • GRP electrical enclosures
  • GRP chemical enclosures
  • GRP gas enclosures

BSEN13706 Specification for Pultruded Profiles defines two grades of structural profiles. Our structural profiles with a wall thickness of over 5mm meet the higher performance E23 grade, while those at 3-5mm thick meet the E17 grade. Please view our Technical Data Table below for further specifications.
