Product name: Rolling barrier / Eva drum / Eva roller barrier / safety roller
Safety rollers can also be called roller barriers, rolling barriers, roller barriers, drum barriers or road rollers, and are widely used in sharp roads or curved areas. The safety roller is a fixed device that not only absorbs vibration energy, but also converts vibration energy into rotation energy, thereby avoiding fatal accidents for drivers and passengers. It is designed to effectively absorb shocks and guide the vehicle back to the direction of the road to prevent major accidents at bends or corners. The safety roller will effectively help the driver to control the vehicle correctly with its obvious color and self-luminous function

Performance of crash barrier
1. The function of safe pressure barricade
1. Reduce speed by baffle
2. Guiding reflections to enable the driver to drive safely
4. When the car crashes, it helps the vehicle turn back to the road by rotating the roller horizontally
5. Minimize the fatal injury of people and vehicles by absorbing the impact of collision
6. Reduce repair costs and maintenance due to roll flexibility.
7. The baffle can slow down the rotation of the rollers, thereby helping to prevent larger accidents.
8.It can be used for many years and the cost is lower.
2. How does the safety fence work?
1. The roller absorbs the impact of collision (impact energy -> rotation energy)
2. The front rail absorbs the second shock
3. The back rail absorbs the third impact
4. Insert the metal pipe to strengthen the pillar.
3. Where is the safety roller guardrail used?
1. Curved middle zone
2. Curved ramp
3. Branch point
4. Curved tunnel
5. Curved downhill
6. Traffic intersection
7. School District
8. Danzer district and so on.
