The performance of the composite product mainly depends on the process of fabrication. The pultruded FRP gratings are assembly of pre-shaped FRP pultruded sections joined together by various mechanical means.
Pultruded FRP profiles provide extremely useful options to offshore designers. Pultruded products due to high fibre-to-resin ratio, helps in achieving higher load bearing capacity. Pultruded gratings have longer span with less deflection as compared to moulded gratings.
The pultruded FRP grating panels can easily be cut and modified to fit almost any plant requirement. In recent times phenolic gratings have achieved significant offshore usage in situations where fire integrity is important. The main advantage of phenolic gratings lies not only in their performance during fire but in their ability to retain significant level of functionality after fire exposure including low smoke emission.
