Studies have shown that approximately 1.25 million people die in road accidents each year. Any research that can be used to reduce this number would be a welcome move. In many cases, vehicles hit guardrails on the side of the road, and this impact can cause greater injuries. Originating in South Korea, rolling barrier technology was created, a rotating guardrail technology that will increase the likelihood of saving lives.
Traditional metal guardrails are essentially strong corrugated metal strips made up of steel plates that are installed along the edge of the road. When a vehicle hits the guardrail, it slows and stops the vehicle, stopping it from turning into the road or from crossing the guardrail. The exact effect depends very much on the speed and size of the vehicle. However, we have found that softer, semi-rigid guardrails can reduce the impact of a collision and help save more drivers' lives.
The Roller Barrier System, developed by ETI in Korea, consists of rotating barrier that not only absorb impact energy, but also convert it into rotational energy, allowing the vehicle to move forward. The rollers are made of EVA, which is more elastic and flexible than other polyethylene resins. It is like rubber, but lighter and more flexible than polyurethane. The rollers have a high shock absorption capacity and the three-dimensional cushioning frame is supported by dense pillars. Reflective film is attached to the barrel to improve visibility.
When a car hits a guardrail made of rollers, the impact is converted into rotational energy. The upper and lower frames of the rollers can be adjusted to minimize the loss of function of the steering system and direct vehicles in the direction they are heading to prevent rear-end collisions.
For common road use posts are placed at 0.7m/1m intervals to secure the rotating barrels for additional load bearing to prevent further vehicle derailment. At the same time, the post installation form is also different, and the post can be used long post, driven into the ground, which can also take the form of long and short with fixed installation. In addition to round posts, the installation components of a roller barrier system include beams, spacers, clips, post caps, bolts and other accessories.
At the same time, although the parts may be damaged upon impact, only the damaged parts need to be replaced because they are independent of each other. Therefore, the rolling barrier installation system will not be expensive to maintain.
It is believed that in the near future, the new rolling barrier system will become a common application choice in various countries. Safebuild company is committed to the technical research of the barrier guardrail system, and can customize the production of high-quality standard rolling barrier according to the different standards of different customers.
