The Bus Body Side Panel Extrusion (Aluminum/FRP) is designed with safety in mind. Both aluminum and FRP offer superior impact resistance, crucial for passenger safety. Aluminum panels absorb and dissipate impact energy, while FRP provides additional energy absorption due to its reinforced matrix, enhancing the crashworthiness of the vehicle and protecting passengers during accidents or collisions.
Our Bus Body Side Panel Extrusion (Aluminum/FRP) solution is sustainable, with aluminum being 100% recyclable. FRP is also engineered for minimal waste during production, making it a more eco-friendly choice. The lightweight nature of both materials also contributes to reduced fuel consumption during transportation, lowering the overall environmental impact of the bus.
