Fiberglass pultruded grating also facilitates the direct flow of car wash water into the trench. There is no water in the car wash working position, and the FRP grille has a strong load-bearing capacity. It can be applied in car washes, urban greening, shipyards, and sewage treatment plants.

Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.
