EVA Rolling Guardrail Roller Anti Crash Guardrail Road Roller Barrier
EVA Rolling Guardrail Roller Anti Crash Guardrail Road Roller Barrier
This guardrail consists of uprights, EVA rotating barrels, U-shaped beams and connectors. All steel components are treated with hot-dip galvanizing to prevent rusting.
The vertical pillars are separated by 1 meter or 0.7 meters, and two rotating barrels are installed on each vertical pillar.
This rotating barrel is made of EVA (ethylene-vinyl acetate copolymer) as the main material, added by more than 30 kinds of auxiliary materials such as PE (polyethylene) and related chemical additives, and was produced under a certain temperature and pressure. With high flexibility and resilience, and also with high temperature resistance, continuous working temperature between -30 °C and 70 °C.
Reflective strips are attached to the rotating barrel. When driving at night, through the illumination of head-lights, it can better reflect the outline of the route, play a better sight-inducing role for the vehicle, improving driving safely.
Applications:
This product can be widely used in the curve sections of highway.
the ramps of highway and continuous downhill sections.
Fan-shaped middle section of curved belt
Cliff or high drop slope section
Bridge terminals
area affected by crosswind
Tunnel entrance
And road sections where accidents occur frequently.
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.
