Fiberglass grating is a plate-like structure with multiple spatial characteristics, which is made by adding fiberglass anti-corrosion chemical fibers to unsaturated aliphatic polyester resin. Due to the addition of fiberglass, it is a plate-like structure with multiple spaces. The excellent corrosion resistance also promotes its application in some engineering projects, which are usually easily eroded but require natural ventilation and permeability. Although laminated glass is known to be highly sensitive, this does not mean that the compressive strength of FRP gratings is relatively low. On the contrary, as this is an application of FRP anti-corrosion chemical fibers and epoxy resin, other chemicals are added to give it enormous compressive strength and ductility. Under normal circumstances, it has high temperature resistance, corrosion resistance, is not easily broken, and can withstand certain working pressures. High quality FRP gratings can be used for twenty years without causing any damage, and their compressive strength can be seen.
