Description
Products Description
safety roller barrier is a fixture that prevent drivers and passengers from fatal accidents by not only absorbing shock energy but also converting shock energy into rotational energy.It is designed to effectively absorb shock and lead vehicle to the road direction to prevent large accidents.
widely used on sharp carve road or bend road zone. Safety roller is a fixture that prevent drivers and passengers from fatal
accidents by not only absorbing shock energy but also converting shock energy into rotational energy. It is designed to
effectively absorb shock and lead vehicle running back to the road direction to prevent large accidents at bend or carve road sites. Safety roller will effectively function for drivers to properly control vehicles with its noticeable color and
self-luminescence.
different from the w beam guardrail.It can absorb shock and lead vehicle to the road direction by roller, to prevent large
accidents. And the roller is more light and easy to install than w beam guardrail. It would be recovery after attach and easy to repaire.
The guardrail is composed of columns, rotating cylinder, u-beam and connecting parts. All steel components are treated with hot-dip galvanized anti-rust treatment.The vertical column is separated by 1m or 0.7m, and two rotating cylinders are installed on each vertical column. This rotating cylinder takes EVA as the main material, and 17 auxiliary materials such as PE and related chemical additives are added.Continuous working temperature is between 60 ° and 70 °.Such guardrails are usually installed on the ramp, continuous downhill and curved road of the expressway.When a vehicle hits a guardrail, the rotation function of the rotating cylinder itself and the good resilience of the cylinder body can greatly reduce the injury degree of the vehicle and the driver, and play a good protective role.There is a reflective strip on the rotating cylinder, and the evening star stone can reflect the outline of the route better through the light irradiation, which can play a good line of sight induction effect on the vehicle and further guarantee the safety of the vehicle.

Features of Safety Roller Barrier
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.
Manufacturing Technique
The rotary anti-collision guardrail is a kind of road guardrail which USES the rotary barrel as the main medium. The rotary barrel can rotate under the impact force, and then drive the vehicle to complete the turning recovery. The rotary anti-collision guardrail is a semi-rigid guardrail
