Highway guardrail is the main form of semi-rigid guardrail, it is a kind of corrugated steel guardrail plate spliced together and supported by the main column of the continuous structure. It uses the soil base, column, beam deformation to absorb the collision energy, and force the runaway vehicle to change direction, return to the normal direction of travel, prevent the vehicle from rushing out of the road, to protect the vehicle and passengers, reduce the loss caused by the accident. Corrugated beam guardrail steel and flexibility, has a strong ability to absorb collision energy and collision avoidance, has a good line of sight induction function, can coordinate with the road shape, beautiful and coordinated appearance, can be used in small radius curves, damage is easy to replace. Combined waveform beam guardrail can be used in the narrow central divider. For vehicles crossing the road (bridge) outside, may cause serious consequences of the section, can choose to strengthen the waveform guardrail.

Highway guardrail utility model involves a highway central divider opening with a combination of waveform plate movable steel guardrail, the guardrail by two pieces of waveform steel guardrail plate and between the two fixed clip put two columns, two columns fixed clip installed in two pieces of waveform steel guardrail plate between. In the normal operation of the highway, the guardrail can be easily inserted into the opening of the pre-set insertion and removal holes, play a role in isolation and protection, while the outer edge of the highway with the guardrail belt echo, neat and tidy, beautiful matching. Vehicle collision, due to the waveform steel guardrail plate has a good collision resistance and energy absorption role, not only is not easy to be destroyed, and at the same time can play a good role in the protection of vehicles and drivers and passengers. When the road maintenance or other reasons need and pass, can easily pull out the opening of each group of guardrail column to move away, open up the channel, easy for vehicles to pass.
