Typical guardrails composed of steel plates cannot guarantee a driver’s’ safety. Softer guardrails protect drivers from shock and provide opportunities to save more drivers’ lives. To minimize the number of accidents, a company called ETI (Evolution in Traffic Innovation) designed “Rolling Barrier System”. The rolling barriers do more than absorb impact energy. They convert that impact energy into rotational energy to propel the vehicle forward rather than potentially breaking through an immovable barrier. The ETI product has a rotating barrel made of EVA with excellent shock absorption power, three-dimensional buffering frames and dense props supporting the frames. Rotating Barrels comes with an attached reflective sheeting for good visibility. EVA has a better flexibility and elasticity compared to other polyethylene resins and has most similar features to rubber. In fact, it’s lighter than rubber and more elastic than urethane. In short, it’s not easily damaged.
The superior performance has been achieved because of its advanced design elements:
1.Roller absorbs initial collision shock, which converts to rotational energy.
2.Front rails absorb second shock.
3.Back rails absorb third shock.
4.Metal pipe inserted between the rails to strengthen the post.
5.Frictional rotating stopper boards installed to the top and bottom of the rollers act as clutch plates to decrease speed.
The product is flame retardant and recyclable. Adding or removing rollers can adjust the barrier for complete suitability to any landscape. Solar powered lights and speed displays can be added when they are warranted.
The arrival of the latest design in safety roller crash barrier systems to the international market reduces repair, replacement and maintenance costs, compared to existing traditional barriers.
