Features of FRP molding grille: 1. Interweaved fiberglass and fully-penetrated resin can maximize the grille’s corrosion resistance. 2. The grille distributes its load onto horizontal and longitudinal grille bars. 3. The grille’s load distribution onto adjacent horizontal and longitudinal grille bars is beneficial to the even stress of the grille and its support layout. 4. The resin’s gloss and oblique grille surface bring the grille the sense of self-cleaning. 5. Pure resin concave surface brings the grille good slippery function. The sand can make its anti-slip effect better.
