Tunnel Opening Roller Crash Barriers Rustproof 20000 Meters Rotating Guardrail
1. Product Introduction
The rotating guardrail combines the advantages of traditional barrier and new type energy -absorption anti-collision roller barrel. It inserts the anti-collision roller barrel into strengthened traditional barrier. When traffic accident happening, the roller barrel can rotate freely on the columns, and through this free rotation of the roller, they break down the impact force of the car. it can efficiently resolve the impact energy by converting the impact energy to rotational energy and pull the accident car back to normal motion trail.

4. Henger's Products Advantage
1) The roller barrel is made of EVA and polyurethane composite material.
This kind of high strength EVA and polyurethane material is elastic and anti-impact and wear-resistant, which can avoid crashing of the roller barrel. when it is impacted, can effectively protect the guardrail and driver and passengers.
2) In addition to good anti-collision and wear-resisting performance.
It also has the advantages of anti-chemical corrosion, anti-ultraviolet aging, weathering resistance and so on. It is not easy to be damaged, and its appearance is exquisite and not faded. In the outdoor natural conditions, the service life is more than 10 years. Once a traffic accident occurs, when the car hits it, the energy of the collision is converted into the rotational energy by the way of rotation, so as to maintain the normal driving direction and speed of the car, so as to minimize the incidence of traffic accidents. To protect the safety of human life and provide a new road safety protection.
3) The roller barrel also has very strong resilience.
Even if they are seriously hit, they can be immediately restored to their original form.
4) The roller barrel has bright color, such as yellow, orange, green, etc., and has high bright reflection effect.
It has eyeball capture function, which can arouse the attention of the driver and reduce the accident rate. Especially to ensure their safety at night and on rainy days.
5. Packing and shipping
For the roller barrel,it would be packed with opp bag+woven bag,or opp bag+woven bag+carton.
And for the guardrail,it would be packed as tie,and also the same as post.Shipping by air or sea as request.
