高速公路护栏板是由两片波形钢护栏板及两者之间固定夹放的两根立柱构成，两根立柱固定夹装在两片波形钢护栏板之间。在公路正常营运时，该护栏利用插拔立柱可方便地插入开口处预先设置的插拔孔内，起到隔离和防护作用，同时与公路外边上的护栏带相呼应，整齐划一，美观配套。
Highway guardrail board is composed of two corrugated steel guardrail plates and two columns fixed and clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail plates. During the normal operation of the highway, the guardrail can be easily inserted into the pre-set plug-in hole at the opening by using the plug-in column, which plays the role of isolation and protection. At the same time, it corresponds with the guardrail belt on the outside of the highway, which is neat, uniform and beautiful.
车辆对其碰撞时，由于波形钢护栏板有良好的耐撞性能和吸收能量的作用，既不容易被撞毁，同时又可对车辆和司乘人员起到很好的保护作用。当路面维修或其它原因需要并通时，可方便地把开口处的各组护栏立柱拔出移走，开辟通道，便于车辆通行。
When the vehicle collides with it, the corrugated steel guardrail plate is not easy to be damaged due to its good crashworthiness and energy absorption function, and it can also play a good role in protecting vehicles and drivers. When the road surface maintenance or other reasons need to be connected together, it is convenient to pull out each group of guardrail posts at the opening to open a channel for vehicles to pass through.
