Yellow EVA Material Highway Safety Roller Barrier ISO Standard

Introduction

Anti-crash highway roller barrier is a new product. It is assembled by PU / EVA rollers and galvanized steel post and beams.But it is different from the w beam guardrail.It can absorb shock and lead vehicle to the road direction by roller, to prevent large accidents. And the roller is more light and easy to install than w beam guardrail. It would be recovery after attach and easy to repaire.

The roller barrier 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 °.

How safety roller barrier works?

1. The roller barrier converts great shock from vehicle collision to rotational energy to absorb shock.
2. Upper and lower frames adjust tires of large and small vehicles to prevent the steering system function loss.
3. The three-dimensional structure of D-shaped frame and buffering bracket distribute and absorb the 2nd shock.
4. Props at an interval of 0.7 m increase bearing power to prevent accident vehicles from going over the guardrail and turning over into a dangerous area.
5. The product has a rotating barrel made of EVA with excellent shock absorption power, three-dimensional buffering frames and dense props supporting the frames.

Advantage

1.Widespread flexibility.

Completely suitable for all weather conditions, the Polyurethane foam safety roller barrier can be installed in the median between opposing traffic flows, on curved median strips, curved ramps, diverging points, curved downhill corners, hillside locations, school zones and in danger zones, protection zones for posts, street lights and general infrastructure within the road reserve.

2.Cost efficient lifecycle.

The lifecycle cost of the Polyurethane foam safety roller barrier out performs traditional crash barrier systems as it requires less frequent repair, replacement and maintenance. More significantly the Polyurethane foam safety roller barrier provides reduced occupant risk of injury.

The cost benefit of the Polyurethane foam safety roller barrier makes it an irrefutable crash barrier solution comparing it to other semi ridged barrier systems.

3.Pure innovation.

Shock absorbing system

Converts shock energy to rotational energy

Decreases speed impact

Redirects vehicles back into its lane

Prevents driver and passenger fatalities

Flame retardant and easy to install

Visually stands out to alert drivers
