Rolling Barrier redirects errant vehicle to the right direction by effectively absorbing impact energy with rollers, upper and lower rails In the event of a traffic accident, Impact-energy is converted into rotational energy, minimizes the incidence of traffic accidents, protects driver’s life and safety, and provide a new road safety and security.
Rotary barrels are made of composite materials made of EVA and polyurethane. This high-strength EVA and polyurethane material is inherently resilient and resistant to abrasion, which prevents the barrel from being crushed and effectively protects the fence and the driver.
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.
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.
