Features of Safety Roller Barrier:
1. Reduce speed by stopper board
2. Guide reflective leads a driver to drive safely
3. Recyclable material (eco-friendly)
4. Help a vehicle turn back to the road by its spinning when the car crashed the rollers laterally
5. Minimize fatal damage of people and vehicles by absorbing collision shock
6. Reduce costs in repairing and maintenance due to Roller’s resilience.
7. Stopper boards help prevent larger accidents by slowing down Roller’s spin
8. Can be used for many years, less cost.
How safety roller barrier works?
1. The rotating barrel converts great shock from vehicle collision to rotational energy to absorb shock.
2. Upper and lower frames adjust tires of large and small vehicles to prevent the steering system function loss.
3. The three-dimensional structure of D-shaped frame and buffering bracket distribute and absorb the 2nd shock.
4. Props at an interval of 0.7 m increase bearing power to prevent accident vehicles from going over the guardrail and turning over into a dangerous area.
5. The product has a rotating barrel made of EVA with excellent shock absorption power, three-dimensional buffering frames and dense props supporting the frames.
The rotary drum is made of EVA (ethylene-vinyl acetate copolymer) as the main material, and more than 30 kinds of auxiliary materials such as PE (polyethylene) and related chemical auxiliaries are added at a certain temperature and pressure. It has high flexibility and resilience, and also has high temperature resistance, and continuous working temperature is between -30℃ and 70℃.
The reflective strip is attached to the rotating cylinder. When driving at night, through the lighting of the headlights, the outline of the route can be better reflected, and the vehicle can play a better induction role to improve driving safety.
