Safety roller barrier or roller guardrail is a fixture prevents 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 large accidents.
Safety roller barrier or roller guardrail is known as a roller barrier,rolling barrier,roller type barrier,drum barrier or roller guardrail,rolling guardrail,drum guardrail,roller type guardrail,rotary barrier,rotary guardrail ,rotary anti-collision guardrail,rotary anti-collision barrier. It is widely used on sharp carve road or bend road zone.The safety roller will effectively function for drivers go properly control vehicles with its noticeable color and self-luminescence.
The safety roller barrier is a new product. It is assembled with PU / EVA rollers and galvanized steel post and beams. The roller barrier differs from the w beam guardrail in the way it functions because It can absorb shock and lead vehicle to the road direction by roller, to prevent large accidents, whilst the W beam does not. The roller barrier is as well lighter and easier to install than w beam guardrail and it would be easier for recovery after attachment and easier to repair.
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 °.These kinds of 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
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.
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.
