TerraGrate® Pultruded Grating is a series of high strength pultruded bars that are the best solution for replacing aluminium and steel gratings in corrosive environments. Pultruded gratings are designed for use in a wide range of industrial applications where longer support spans are required.


TerraGrate® FRP Pultruded Grating is manufactured by assembling two structural fibreglass T bearing bars into a grid pattern. The T bars structural shapes are made by pultrusion – a continuous moulding process utilising fibre or glass reinforcement in a polyester or vinyl ester resin. Selected reinforcement materials are thoroughly infused with the high-quality resin, the fibrous laminate is formed into a geometric T shape and pulled through the heated steel dye. This solidifies into the exact shape of the dye cavity as it is being continuously pulled by the pultrusion machine.
