GRP FlowGrate Micromesh

Similar to our Standard FlowGrate, FlowGrate Micromesh / Mini Mesh GRP grating has been designed to provide a high strength, lightweight and durable solution for walkways, platforms, gullies and drainage covers.

With reduced size square apertures that are sub-divided and have shallow bars to meet 20mm ball proof testing.

The Isophthalic Polyester Grating panels are suitable for general use where factors such as high-strength, non-conductive, lightweight and corrosion resistant applications are required.

FlowGrate Micromesh GRP gratings are up to 50% lighter than steel gratings and are finished with a hard wearing anti-slip gritted surface – compliant to National and Internationally recognised standards.

This product is also available in Phenolic with its excellent Fire Retardant Properties that meet BS476 Part 7 Class 0 and section 12 of London underground standards for low smoke and low toxicity use in tunnels.
