FRP Grating is manufactured using an Isophthalic Polyester which has very good chemical resistance, good flame resistance and is the best general-purpose resin available. (Other resins available are Vinyl Ester and Phenolic, available for custom orders)
Pultruded Grating generally has higher strength than Molded Grating due to the production process leading to more consistent fiber orientation and even resin distribution. Therefore, Pultruded Grating is often used in applications requiring high strength or heavy loads. However, for chemical resistance, Molded Grating is stronger because its resin content is higher than that of pultruded grating.
