Purpose-designed GRP riser decking and framework to help reduce the risk of death and serious injury on construction sites.

Features and benefits:

  • Can eliminate the need for scaffold handrails, netting or timber shuttering.
  • Can be post-fixed' or 'cast-in' to concrete as a fully structural solution.
  • Choice of d² gratings, depending on ventilation, safety and load bearing priorities.
  • Low-maintenance.
  • Anti-slip.
  • Non-conductive: does not require earthing, no risk of electrical hazards.
  • Up to 80% lighter than steel grating: easily transported and manually handled into position (no need for heavy lifting equipment).
  • Gratings can be easily cut on site, allowing easy adaptation for service holes etc.
