The rolling guardrail formed by the post, rolling cylinder, u-shaped beam and fittings of all steel components adopts hot-dip galvanized processing。

Post interval of 1 m or 0.7 m, each post is installed on two rolling cylinder. The rolling cylinder with EVA (ethylene/vinyl acetate copolymer) as the main ingredient, adding PE (polyethylene) and related chemical agents such as *7 kinds of accessories, under a certain temperature and pressure,to shaped out as a whole cylinder, high flexibility and resilience, and high temperature resistant performance, 

Continuous working temperature between *0 ° C and *0 ° C. This cylinder is normally installed in freeway on-ramp, continuous downhill and bend. 

When the car crashed into the guardrail, the rotation of the rolling cylinder itself function and good resilience of  cylinder, can greatly reduce the damage degree of the vehicle and driving personnel, have good protection effect.
