This article provides a 5-step method for FRP grating design and selection: ① Define design criteria (deflection ≤ 6mm, deflection over 12mm not recommended, prioritizing performance); ② Identify constraints (load-bearing bar dimensions, supports, etc. to be considered); ③ Select resin (polyester/vinyl ester/phenolic resin each for specific scenarios); ④ Optimize span (calculate maximum span to determine supports); ⑤ Choose appearance (options for color, roughness, and topcoat available).
