They are highway anti-collision facilities, consisting of two corrugated steel guardrails and two guardrail posts fixed between them. They are mainly used to force out-of-control vehicles to change direction when hit by a vehicle, thereby preventing them from running off the road. They absorb collision energy through deformation of the soil base, posts, beams and endurance plates, so that the corrugated steel guardrails have good collision resistance, energy absorption and protection, and are not easily destroyed, while providing good protection for vehicles and drivers and passengers. In the existing technology, most corrugated guardrails have poor anti-collision performance and energy dissipation effects, and require collision deformation to dissipate energy.
