wave form guardrail The utility model relates to a combined corrugated plate movable steel guardrail used at the opening of the highway median separator. The guardrail is composed of two corrugated steel guardrails and two columns clamped between them. The two columns are clamped between two corrugated steel guardrails. During the normal operation of the highway, the guardrail can be easily inserted into the pre set plug hole at the opening by using the plug column to isolate and protect. Together with the guardrail belt on the outside of the highway, the guardrail is neat, uniform and beautiful. When a vehicle collides with it, because of its good crashworthiness and energy absorption function, it is not simply destroyed, but also can play a better role in protecting vehicles and drivers and passengers. When the road surface is repaired or other reasons require parallel connection, it is convenient to pull out and remove each group of guardrail posts at the opening, and open a wasteland channel for vehicles to pass.
