Highway Roller Barrier Anti-Collision Guardrail

What is Rolling Barrier?

Rolling Barrier redirects errant vehicle to the right direction by effectively absorbing the impact energy with rollers, upper and lower rails (the impact-energy is converted into rotational energy).

Our Safety Roller Crash Barrier, defined as a “semi rigid” safety barrier, demonstrated extremely high performance scores in three key rating areas:
* Structural Adequacy – the ability for the barrier to remain functional post a crash impact. This is a critical when considering the time to repair barriers after a crash event
* Occupant Risk – the ability to minimise impact injury to vehicle occupants
* Vehicle Trajectory Post Impact – the ability to keep a vehicle’s movement directed in the direction of original travel. The key being assessed is the redirection angle to minimise or eliminate the likelihood of an errant vehicle being driven into oncoming traffic lanes, or into pedestrians on the roadside, property or furniture

Key Features

* Easy installation and maintenance on curved road
* The high-elastic synthetic resin roller is hardly damaged by impact. (Cover: PE, Core: Urethane)
* Powder coating on rails with various colors is available upon request.
* Minimizes damage on motorists and vehicles with rollers and dual guardrails.

The roller system is best suited to installation at high risk sites on curves or at the entrances or exits to highways. It also
can be supplied with an end treatment. The representative said, “The key is in the absorbent material that reduces the impact forces.”

The rollers are made from an ethyl vinyl acetate (EVA) material that is highly shock absorbent, a key design feature. This
material is also said to be durable, long lasting and chemically resistant, while not suffering ageing due to UV exposure.

Following an impact with the roller barrier, the vehicle speed is reduced due to the impact absorbent properties of the rollers.
The system also deflects vehicles at a shallower angle while causing less damage than conventional barrier types.

The standard colour choice for the rollers is yellow, although other options available from the firm include grey, red and green.

Other novel barrier products from the firm meanwhile include anti-glare screens that can be installed on highway curves as well asexit and entry ramps to prevent the lights from oncoming vehicles dazzling drivers. The firm is also testing a new metal screen system designed to cover over upright barrier posts and improve safety for fallen motorcycle riders.
