It consists of a specially manufactured frame rail, shock-absorbing swivelling polymer barrels and specially designed bolts, lockers and supports. It forms a rail structure in which sit the barrels. Importantly, the rails are flexible enough that they can be easily structured to match the curve’s radius.
This product is the world's only original rotating guardrail that differentiates itself from other companies by applying a rail sliding shock absorption system that absorbs maximum shock when a vehicle collides with the guardrail.
Rolling Guardrail Barrier never crumbles from external blows and has better ability to absorb a shock than any other guardrails, according to the company. When a car hits the Rolling Guardrail Barrier, the barrels move the vehicle along, absorbing some of the shock but redirecting the vehicle along curve’s radius.
In effect, the barrier converts the impulse energy of the crash to rotational energy within the barrier system. The barrels can be easily removed and replaced when damaged after an impact.
ETI said it is now pushing into Europe and already has around 20km of the barrier system installed along Romanian roads.
