The installation position of the corrugated guardrail has different anti-collision performance

The configuration of the wave beam guardrail board depends on different road conditions and configuration positions, and its anti-collision performance requirements are different. The guardrails installed on the roadbed are divided into two levels A and S according to the anti-collision level, and the anti-collision level of the middle dividing guardrail is Am and Sm. Through the general protection of the handrail and the correct guidance of the vehicle, it is an integral action to guarantee the safety of the occupants of the vehicle from collision.
