Customized Color Highway Guardrail Traffic Safety Anti-Collision
Roller Barrier
Composed:
Roller Barrel, beam, column, reflective strip, sleeve, convoluted
ring, U-shaped connector, bolt, column cap, end
Material:
Roller barrier system is made of high-grade environmental
protection material EVA foam, which has the characteristics of
flame retardancy, acid and alkali resistance, and high temperature
resistance.
Metal parts are hot-dip galvanized materials.
Features:
1. The rotating barrel has the characteristics of flame retardancy,
acid and alkali resistance and not easy to age.
2. The color of the rotating barrel can be customized according to
customer needs.
3. The distance between the two barrels of the rotating guardrail
is usually 0.7M and 1M.
Application
1. Highway ramp
The ramp is also a place where traffic accidents are prone to
occur. Because the road is narrow, it is a test of the driver's
driving skills. When a novice driver is driving on the ramp,
traffic accidents are likely to occur, ranging from damage to the
vehicle to breaking the guardrail and rushing down the hill.
Therefore, rotating guardrails are used on many high-speed ramps.
2. Road bend area
Usually there will be a lot of vehicles coming and going at the
turning. When the vehicle is driving at the turning at high speed,
traffic accidents will easily occur. Therefore, our protective
guardrail will be installed at the turning of the road in many
areas, which can effectively protect the safety of drivers and
passengers.
3. Cliff edge
The edge of the cliff is the place where traffic accidents are most
likely to occur. When the vehicle is driving on the highway at the
edge of the cliff at high speed, it is a test of the driver's
control of the road conditions. If there is a slight mistake, the
driver will break through the guardrail and rush down the cliff ,
so it is necessary to install a rotating guardrail on the edge of
the cliff, because the rotating guardrail can absorb energy and
convert kinetic energy into rotational energy, thereby forcing the
vehicle to continue moving forward at a slow speed.
4. Fork in the road
There are many vehicles passing through the fork, and the use of
traditional guardrails may not protect the personal safety of
drivers and passengers well.
The rotating guardrail itself is brightly colored, which can warn
drivers and also play a decorative role. The rotating guardrail can
adapt to all environments and weathers.
