Trench Grates

FRP (fibre reinforced plastic) trench grates are available for wet drainage areas where slips and corrosion calls for a more robust long lasting non slip open mesh trench grating or drain grate material.

Manufactured from our standard molded FRP grating panels, we can supply grates in standard 1220mm lengths that are both easy to handle and install.

FRP Trench Grates are UV treated and available with a non slip embedded grit top. Ideal for use outside where slips and falls occur on metal grating in wet drainage areas or where mould and residue normally occurs creating an unsafe walking surface. “grate” for coastal areas where salt & environmental corrosion takes place.

Standard length 1220mm
Standard widths 160mm, 200mm and 312mm
Standard thickness 25mm and 38mm thick


Other widths and lengths can be supplied, please contact the office.
Slate Grey colour is standard. Green and yellow can also be supplied

For new concrete trench work we also carry our FRP Concrete Embedment Angle.
This is available for both our 25m and 38mm thick FRP Trench Grates.


  • Non Slip Embedded Grit Top
  • Corrosion and chemical resistant
  • UV treated
  • Light Weight for easy cleaning and maintenance
  • Choice of colours
  • 316 s/s hold down clip system available to suit.

The profile of the embedment angle allows it to be set into the concrete at the time of pouring, never coming away from the concrete. Being FRP (fibre reinforced plastic) it will always be corrosion resistant.
