A foamed material, upon impact, rapidly compresses and absorbs impact energy, reducing damage to the steel plate and internal structure. An outer fiberglass cladding effectively resists external erosion such as ultraviolet rays, rainwater, and chemicals, protecting internal materials from damage. An anti-corrosion polyurea protective layer resists various chemical corrosions, preventing rust and corrosion during use. The crash barrier effectively absorbs and disperses the energy generated when ships or vehicles collide with bridges, significantly reducing damage caused by accidents. This protects the integrity and stability of the bridge structure, as well as the safety of vehicles and pedestrians. Furthermore, it reduces bridge structural damage caused by impacts, extending the bridge's service life and reducing maintenance and reconstruction costs. Attached Figure Description
