Pultruded Gratings ARHAM†Pultruded Grating is assembled pultruded H-sections or T-sections linked by rod per distance into panel. The distance is decided by an open area rate. Pultruded grating provides extremely high unidirectional strength and stiffness, since H-section or T-section can provide great mechanical load whereas the rods work as Connector. Pultruded Grating are stronger than Molded Grating because of the higher glass content. FRP Pultruded Grating can span long distance for any given load. Of course, Pultruded Grating can be gritted or covered panel. However molded grating is more corrosion resistant than Pultruded Grating using the same resin system.
