The highway guardrail board is composed of two corrugated steel guardrail boards and two columns fixed between them, and two columns fixed between two corrugated steel guardrail boards. In the normal operation of the highway, the guardrail can be conveniently inserted into the pre-set plug hole at the opening by using the plug-out column, which can play the role of isolation and protection, and at the same time, it can echo with the guardrail belt on the outside of the highway, uniform and beautiful matching.

When the vehicle collides with it, because the corrugated steel guardrail board has good crash resistance and absorbs energy, it is not easy to be destroyed, but also can play a good protective role for the vehicle and the ride personnel. When pavement maintenance or other reasons need to be connected, it is convenient to pull out and remove the various groups of guardrail columns at the opening, and open up channels to facilitate the passage of vehicles.

Highway crash guardrail is a typical cold-formed steel product. It has the advantages of good impact resistance, low cost, long life, higher safety and environmental protection. Purpose: highway anti-collision facilities, isolation and other facilities.

1. corrugated beam guardrail is the main form of semi-steel guardrail, it is a continuous structure which is spliced with each other by corrugated steel guardrail board and supported by column.

 2. it uses the deformation of soil foundation, column, beam to absorb collision energy.

 3. corrugated beam guardrail steel is flexible.

 Common specification for two wave guardrail boards is 4320 mmx310mmx85mmx3/4mm..

 Common specification for three wave guardrail 4320mmx506mmx85mmx3/4mm.
