These Guardrails Have Shock-Absorbing Rollers That Stop Cars from Diverting and Causing a Secondary Crash

ETI (Evolution in Traffic Innovation) Co., Ltd. has developed the ETI Roller Barrier System, in which guardrails are equipped with rollers that cushion the impact of collisions. Essentially, these guardrails convert collision energy into rotational energy to prevent cars from diverting off the road and causing a secondary crash.

These innovative guardrails have super-bright reflectors that improve drivers’ visibility. The shock-absorbing rollers (or rolling drums) are made up of EVA material, which has good flexibility and elasticity compared to other polyethylene-based resins. It’s similar to rubber, but lighter.



The design of the tightly spaced struts forms heavy-duty support to prevent the crashed vehicle from overturning the guardrail into a possibly hazardous area. Its ‘D’ frame’s three-dimensional structure and shock-absorbing bracket are responsible for absorbing the secondary shock. Drivers won’t lose their steering capability as the guardrails’ upper and lower frames correct the tires of large and small cars.
