Features:
1. The guardrail is composed of uprights, rotating barrels, U-shaped beams and connectors. All steel components are hot-dip galvanized to prevent rust.

2. The columns are separated by 1 meter or 0.7 meters, and two rotating barrels are installed on each column. The rotating barrel is made of EVA (ethylene-vinyl acetate copolymer) as the main material, added with 17 kinds of auxiliary materials such as PE (polyethylene) and related chemical additives, and is produced under a certain temperature and pressure, and has extremely high flexibility. It has high thermal resistance and high temperature resistance, and can continue to work at temperatures between -60°C and 70°C. This type of guardrail is usually installed at the ramp of the highway, continuous downhill and bends.
3. When the vehicle hits the guardrail, the rotation function of the rotating barrel and the good resilience of the barrel body can greatly reduce the degree of injury of the vehicle and the driver, and play a good protective role.
4. Reflective strips are attached to the rotating barrel. When driving at night, through the illumination of lights, it can better reflect the outline of the route, play a better sight-inducing effect on the vehicle, and further ensure the safety of driving.
