Highway Roller Barrier Anti Crash Eva Material Roller Guardrail

High Way Roller Barrier Anti Crash Eva Material Roller Guardrail

The Rolling Barrier Guardrail System is new generation guardrail which combines rotating barrels made from the energy-absorbing co-polymer Ethylene-vinyl acetate (EVA), with a proprietary steel guardrail, to create the world’s safest roadside and median barrier.

The Rolling Barrier Guardrail was built with maintenance as a primary concern. A modular design comprised of D-shaped steel rails, round steel-posts with EVA shock-absorbing barrels, and frame rail lockers means that after incidents, individual parts can be replaced without compromising the entire system thus reducing maintenance costs.

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.

Advantages:

1. The rotating element of the Rolling Barrier Guardrail has highly visible reflective sheeting bands which provide safe reflective warning to the night time driver.

2. The Rolling Barrier Guardrail can be used on dangerous curved roads, severe radius exit and entrance ramps, bridge decks, entrances to tunnels as well as general safety barriers to potentially hazardous roadside facilities.

3. Symmetric design allow for installation on roadside and as median barrier guardgdrail to prevent serious injury and fatality.

4. Rolling Barrier Guardrail has passed the stringent requirements of the crash tests with superior re-direction and minimum deflection performance as compared to traditional road safety barrier products. Crash test results showed minimal to no damage to the Rolling Barrier Guardrail after impact which can be attributed to its energy-distributing design. Minimal damage combined with its modular component-based design will reduce overall maintenance costs.

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.
