Highway Guardrail/Safety Rolling Barrier
The base metal materials used for the columns, beams, gyroscopic
rings, ends, and column caps of the rotating cylinder guardrail are
For carbon structural steel, its mechanical performance index is
not lower than the requirements of Q235 grade steel stipulated in
GB/T700
beg. The base metal material used for bolts, nuts, etc. is carbon
structural steel, and its tensile strength is not less than
375N/mm2. The reflective strip should use a first-class reflective
film as the retroreflective material, and the material should be
soft
Non-toxic materials, other properties should meet the requirements
of GB/T18833 and JT/T388.
They consist of both flexible property and semi rigid property of
barrier stiffness. RB are different in mechanisms than the other
types of normal barriers. It also reduces the hazard and road
accidents.
Urethane has become the material of choice in so many of today’s
performance driven applications because it illustrate extraordinary
physical and mechanical properties that other material simply can’t
match.
Roller Barriers absorbing the collision shock in three points, the
barrel, the buffering bracket, and the liquidity of the rail
shocking mechanism. The shock energy absorb from a curved crash is
absorbs then the shock is converting in a rotational energy. Shock
energy absorbs the gain by its upper and lower safety guard rail.
Shock energy will be again by the back side of safety rails.
1. Adopt high-quality original material
Roller EVA material with elastic characteristics is used as raw
material, which can slow down the lateral impact process of the
out-of-control vehicle. Moreover, the rotating barrel can rotate
around the column under a certain impact, driving the
out-of-control vehicle to return to the correct driving direction.
2. High quality steel support
Using Q235 steel, multiple thick steel fixed, durable, strong
protection ability.
3. Strong of lower solid frame
The round post could buried deep, structural strengthening, can
effectively block the front or side impact.

Product Usage:
The appearance color of the rotating anti-collision barrel can be
customized into various warning colors, such as yellow, orange,
orange, red, green, etc. The high brightness reflection effect
makes the anti-collision barrel maintain high recognition and
warning degree in bad weather conditions such as night and rainy
days, catch the driver's eye, attract the driver's attention, and
reduce the accident rate. It is especially suitable for
installation in accident-prone areas such as tunnel entrances,
central isolation belts, rapid turning areas, and complex
intersections; because of its good anti-collision performance, it
can also be used as various power facilities, parking lot columns,
large shelf corners and other objects. defensive equipmentrubber.
