GRP Flowgrate

FlowGrate GRP grating has been designed to provide a high strength, lightweight and durable solution for walkways, platforms, gullies and drainage covers.

The reduced mesh size allows effective drainage and debris fall prevention when used as flooring.

The panel can be utilised as a debris litter screen and/or machine guarding when used vertically.

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 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.
