PU Material Highway Safety Roller Barrier For Traffic Protection
1. Introduction
Roller Barrier with "one upright four guardrails", can prevent the
car through the fence, out of the driving lane effectively by
strengthening the performance and installation of upright and
guardrails. Roller Barrier use a rotating structure, install the
roller barrier on the upright and make it rotate freely. This free
rotation can disassemble the force of percussion from the car. And
it will be adsorbed and reduced by the roller barrier effectively.
So it can decrease the influence caused by traffic accidents.
rolling system will create a new traffic protection way.

3. Working principle
The highway protective rolling guardrail mainly adopts the "one
column and four beams " method . By strengthening the performance
and installation method of the column and the fence, it effectively
prevents the car from crossing the fence and driving out of the
driving lane.
On the other hand, the new anti-collision bucket guardrail has a
built-in anti-impact energy-absorbing rotary anti-collision barrel,
and the flexible barrel with anti-collision
and energy absorption is mounted on the column, so that the
rotating barrel can rotate freely on the column. By the free
rotation of the rotating bucket, the impact force of the car is
decomposed, and the impact force perpendicular to the direction of
the guardrail is decomposed into a direction parallel to the
guardrail, so that the impact force is effectively absorbed and
reduced by the rotating barrels , thereby effectively reducing the
possibility of traffic accidents .
The highway protective rolling guardrail is made of EVA and
polyurethane composite. This high-strength EVA and polyurethane
material itself has elastic and anti-collision and wear-resistant
advantage. It can prevent the rotating barrel from being crushed
when it is impacted and effectively protecting the guardrail and
the passengers. Besides the well anti-collision and wear
resistance, it also has the advantages of chemical corrosion
resistance, UV aging resistance, weather resistance, etc. It is not
easy to break, and the appearance is exquisite and not easy to
fade. Under outdoor natural conditions, the service life is at
least ten years.
4.Features
4.1 Wear resistance is higher than 200%
Wear resistance is higher than 200% to other anti-collision barrel
materials in the market . Due to its unique production process and
process, Taicheng Rotary Anti-collision Barrel has 3mm thick hard
polyurethane protective layer in the outer
Qingdao Taicheng Transportation Facilities Co., Ltd
layer of the barrel. Its tensile strength and bearing capacity are
2-3 times that of other anti-collision barrels in the market.
4.2 High quality, high flame retardancy
Acid and alkali resistance, high temperature resistance and low
temperature resistance, radiation resistance, impact resistance,
aging resistance, high flame retardancy.
The outer protective layer makes the barrel itself have a high
flame retardant rate, preventing secondary fires in traffic
accidents from burning the rotating barrels . Other similar
materials anti-collision barrels are not flame retardant, they are
burned in case of fire and have a strong open flame.
4.3 Rotating barrels are bright in color
With high brightness ( yellow, orange, green, etc., )and reflection
effect. They have eyeball capture function, which can cause the
driver's attention and reduce the accident rate, especially to
ensure their nighttime and Driving safely on rainy days.
4.4 Easy to install
The new rotary anti-collision guardrail series adopts modular
design, the whole installation is simple and quick, no need for
professional guidance, the installation is safe and pollution-free,
and the installation cost is low.
4.5 Low cost after sale
The energy-absorbing anti-collision barrel has strong wear
resistance and impact resistance. The rotary anti-collision
guardrail is designed firmly. It is not necessary to replace the
guardrail for ordinary traffic accidents, can save a lot of
after-sales and
maintenance costs.
4.6 Beautify Environment
Compared with the traditional guardrail, the rotary anti-collision
guardrail is beautiful
and colorful. In addition to the high degree of warning, it can
also beautify the surrounding environment, especially in the
beautiful scenery of the mountainous area, forming a unique
combination with the surrounding scenery.
5. Overview
The color of the rotating anti-collision bucket can be customized
into various warning colors such as yellow, orange, orange- red,
green and so on. The high degree of bright reflection effect makes
the anti-collision barrel maintain high recognition and warning
degree in the bad weather conditions such as nighttime and rainy
days, catching the driver's eyeball and also can catch the driver's
attention and reducing the accident rate.
It is especially suitable for installation in accident-prone areas
such as tunnel openings, central isolation belts, sharp turning
areas, and complex intersections. Because of its good
anti-collision performance, it can also be used as defensive
equipment various power facilities, parking lot columns, large
shelf angles and other objects.
