Safebuild New PU/EVA Safety Roller Crash Guardrail

Safebuild Roller Crash Barrier, also called Safety Roller Crash Guardrail, is a kind of safety protection guardrail that can absorb impact energy, but also can convert the impact energy into rotational energy, effectively absorbing the impact, guiding the vehicle to the direction of the road and preventing the occurrence of major accidents.

Roller Crash Barrier is a new type of guardrail. It is assembled by PU/EVA  roller and galvanized steel post and beam, but unlike W Beam Guardrail, it can absorb impact and guide vehicles to the road direction through rollers to prevent major accidents. Compared with the W Beam Guardrail, the roller is lighter and easier to install. The guardrail consists of posts, rollers, U beams and spacers, which can be recovered after installation and easy to maintain. All steel components are hot-dip galvanized for rust prevention. The posts are spaced 1m or 0.7m distance, and the roller is installed on each post. The roller is made of EVA and polyurethane as the main materials, with a variety of auxiliary materials such as PE and related chemical additives.

Roller Crash Barriers usually installed on ramps, continuous downhill and curved roads of highways, tunnel entrances, ramp entrances, or mountainous roads. When the vehicle hits the guardrail, the rotating function of the roller itself and the good resilience of the barrel can greatly reduce the injury degree of the vehicle and the driver, and play a very good protective role. At the same time, the reflective strips on the roller play a warning role, and the reflective strip can better reflect the outline of the route through the light irradiation, and play a good line of sight induction effect on the vehicle to further ensure the safety of the vehicle. The rubber buckets of Roller Crash Barriers are made of EVA and polyurethane mixture, and the color can be selected according to the customer's requirements such as yellow, orange and so on. The roller is made from a mold and has no noticeable skew. When Roller Crash Barriers are hit by a vehicle, the rollers can rotate under the impact force, so that the driving trajectory of the uncontrolled vehicle is changed from the vertical direction to the direction of the guardrail, in order to defuse the impact force and reduce the severity of the collision. Due to the excellent elasticity and resilience of the roller, the rolling guardrail can not only avoid being damaged during the collision, but also effectively protect the uncontrolled vehicle and passengers.
