Product Introduction
The rotating guardrail combines the advantages of traditional
barrier and new type energy -absorption anti-collision roller
barrel. It inserts the anti-collision roller barrel into
strengthened traditional barrier. When traffic accident happening,
the roller barrel can rotate freely on the columns, and through
this free rotation of the roller, they break down the impact force
of the car. it can efficiently resolve the impact energy by
converting the impact energy to rotational energy and pull the
accident car back to normal motion trail.
Henger's Products Advantage
1. The roller barrel is made of EVA and polyurethane composite
material. This kind of high strength EVA and polyurethane material
is elastic and anti-impact and wear-resistant, which can avoid
crashing of the roller barrel. when it is impacted, can effectively
protect the guardrail and driver and passengers.
2. In addition to good anti-collision and wear-resisting
performance, it also has the advantages of anti-chemical corrosion,
anti-ultraviolet aging, weathering resistance and so on. It is not
easy to be damaged, and its appearance is exquisite and not faded.
In the outdoor natural conditions, the service life is more than 10
years. Once a traffic accident occurs, when the car hits it, the
energy of the collision is converted into the rotational energy by
the way of rotation, so as to maintain the normal driving direction
and speed of the car, so as to minimize the incidence of traffic
accidents. To protect the safety of human life and provide a new
road safety protection.
3. The roller barrel also has very strong resilience. Even if they
are seriously hit, they can be immediately restored to their
original form.
4. The roller barrel has bright color, such as yellow, orange,
green, etc., and has high bright reflection effect. It has eyeball
capture function, which can arouse the attention of the driver and
reduce the accident rate. Especially to ensure their safety at
night and on rainy days.
