The Orange Road Rotating Guardrail Is Used For Protection And Anti-Collision, And Is Used For Dangerous Road Sections
Safety roller barrier is a fixture that 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 prevent large accidents.
It is also known as a roller barrier, rolling barrier, roller type barrier, drum barrier or highway roller, and widely used on sharp carve road or bend road zone. The safety roller will effectively function for drivers to properly control vehicles with its noticeable color and self-luminescence.

Product Material
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.
