Roadway Traffic Safe Rolling Type EVA Safety Roller Barrier For Highway Guardrail
Roadway Traffic Safe Rolling Type Safety EVA Roller Barrier For Highway Guardrail
Ldeal for roadside or median applications, our Safety Roller Barrier (SRB) MASH TL-4 longitudinal barrier is designed to minimize damage on impact by safely converting crash energy into rotational energy. SRB’s highly resilient design allows it to sustain minor impacts and smoothly redirect vehicles with less damage to the vehicle and safety roller barrier system.
Advantages:
Improve roadside visibility – SRB rollers are striped with high-intensity reflective sheeting that increases driver awareness and reduces accidents. Optional LED guide lamps can be added for even more exceptional visibility.
Safely change the direction of the vehicle - shock-absorbing rollers convert impact energy into rotational energy for smooth change of direction. Passenger crash test results show that the SRB is the safest in its class.
Vehicle collision mitigation - The SRB is made of steel and flame retardant, environmentally friendly vinyl acetate (EVA) plastic, with 100% recyclable parts to mitigate vehicle collisions and reduce vehicle damage.
Design Drawing:
Rolling guardrail construction with maintenance as the primary consideration. The modular design of D-shaped rails, round steel columns with EVA shock tanks and frame rail lockers means that in the event of an accident, individual components can be replaced without affecting the entire system, reducing maintenance costs.
1. Easy installation and maintenance of curves.
2. Powder coatings of various colors can be provided on request.
3, minimize the damage to the driver and vehicles with rollers and double guardrail.
4, high elastic synthetic resin roller is not easy to damage due to impact (Cover: PE, Inner Core: polyurethane).
Compared with other anti-collision drum materials on the market, the wear resistance is higher than 200%. Due to its unique production process and technology, the external layer of the barrel is 3mm thick rigid polyurethane protective layer. Its tensile strength and carrying capacity are 2-3 times that of other collision avoidance drums on the market.
