Guardrail utility model involves a highway median strip opening with a combination of movable type corrugated plate steel fence, the fence between the two pieces of the corrugated steel fence panels and two retaining clips put two columns constituted two columns fixed interposed between two sheets of corrugated steel fence panels. Waveform fence is the main form of semi-rigid guardrail, it is a corrugated steel fence panels to each other by stitching the main pillar supporting continuous structure. It uses the soil base, column, beam deformation to absorb impact energy and force out of control of the vehicle to change direction, to return to the normal direction of travel of the vehicle out of the road to prevent the outside, in order to protect the vehicle and passengers, to reduce the loss caused by the accident. Beam guardrail steel soft phase and, with a strong ability to absorb collision energy, has good sight inducing function, can be coordinated with the road alignment, beautiful appearance, can be used on small radius corners, damaged place easily replaced. Combination beam guardrail can be used on a narrow median strip. For more way out of the vehicle (bridge), the sector may cause serious consequences, can choose to strengthen beam guardrail.

During normal operation of the highway, the fence post can easily use plug into the opening pre-set plug hole, played the role of isolation and protection, while the road outside the fence with echoes, uniform, beautiful package. When their vehicle collision, due to the corrugated steel fence boards have good crashworthiness and energy absorption effect, it is not easy been destroyed, while at the same vehicles and passengers to play a very good protection. When a road maintenance or other reasons and pass required, you can easily put the opening of each group pulled fence post removed, opening up channels for easy passage of vehicles.
