The advantages of roller guardrails are as follows:
1. The rotating drum is made of a composite material of EVA and polyurethane, which is elastic and collision resistant, preventing it from being crushed during impact. It also has strong resilience and can be immediately restored to its original state even if severely impacted.
2. The appearance of the rotating bucket is bright and has a high degree of light reflection effect, which can attract the driver's attention and reduce the incidence of accidents. It is widely used in countries such as South Korea, Japan, and the United States, and has also begun to be used in some regions of China. The death rate of traffic accidents in the use area has been reduced by more than 90%.
3. The characteristic of a rotating bucket - rotation! When a vehicle collides with a guardrail, these tubes will roll, effectively reducing the consequences of traffic accidents, greatly absorbing the impact force and reducing the impact.
