EVA Traffic Safety Highway Used Anti Corrosion Roller Barrier
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.
Product Description:
· Features of Safety Roller Barrier
·Reduce speed by stopper board
·Guide reflective leads a driver to drive safely
·Recyclable material (eco-friendly)
·Help a vehicle turn back to the road by its spinning when the car
crashed the rollers laterally
·Minimize fatal damage of people and vehicles by absorbing collision
shock
·Reduce costs in repairing and maintenance due to Roller's
resilience.
·Stopper boards help prevent larger accidents by slowing down
Roller's spin
·Can be used for many years, less cost.
Advantages:
Low cost
High flexibility to install and repair
Cable tension and post space can be adjusted.
Prevent vehicles from running off the road effectively
Absorb most sudden impact energy during collision
Good looking for the usage in open scenic spots
Anti-rust, anti-corrosion and anti-aging
Reflective strips can be pasted on the rotating barrel to warn
drivers at night. When the driver drives to an area without lights
or the lights are too dark, the reflective strip can refract the
light, thereby reminding the driver to drive safely.
