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.
