Flexible Highway Reflective Guardrail

Flexible Reflective Crash Barrier for Highway Safety

Highway / Highway Safety Reflective Guardrail, Item No.: AN-PC-9

Highway / Highway Safety Reflective Guardrail

  • Item No.: AN-PC-9
  • Character: After impacting the vehicle with excellent rigidity and toughness, most of the impact force can be absorbed, which is not easy to cause a rebound effect, can make the guardrail body and vehicles, personnel by the best safety protection.

Product Description

Foreword:
  • For a long time, the streets are metal barrier to the sidewalk with the Road Vehicle (or non-Road Vehicle) isolation to ensure smooth traffic and pedestrian safety. However, the metal barrier has also limited the use of steel has been a lot of resources to spend.
  • Metal barrier have to spent hight tost, today's era of rising steel prices, people are vulnerable to pretenders with the theft; and the annual cost of high conservation. At the same time, the rigid metal barrier characteristics are determined in the event of a traffic accident and hit the metal guardrail of the vehicles are often severely damaged.
  • Pc flexibility of the new M-reflective barrier to the impact-resistant engineering plastics extrusion molding can be monotonous to replace the traditional steel barrier material; because it has a certain toughness and steel, tested and certified in strength, the use of up to a certain standard, Once the vehicle was hit in a certain extent to prevent and reduce fatal car crash, such as the loss of a major accident.
  • The color barrier for its products coupled with reflective plate decorated with the design rules, not only to beautify the road, more warning and guidance functions, in addition to the increase in the road outside is more beautiful at night to strengthen the road safety, broke through the plain Protection of traditional road facilities.
The barrier has the following characteristics:
  • The density of low, light weight, the proportion of only one-eighth of ordinary steel.
  • Good corrosion-resistant properties and non-magnetic.
  • High mechanical strength, close by steel.
  • High-temperature resistant, good weather resistance.
The advantages of this barrier:
  • With ultra-high steel and toughness, impact resistance, and a buffer effect of energy dissipation.
  • To construction safety and simple, reduce costs and improve the performance.
  • Long service life, and conservation is much lower than the cost of metal materials.
  • Lively colors, the effect of road landscaping.
  • At night there are reflective warning and guidance functions.
  • The use of renewable sources of recyclable, environmentally friendly conditions.
  • Special materials and fixed mothed, is not easy to steal.
  • Good replace, wide range of uses, market and competitive.
  • Can be combined with other metals and non-metallic industry over the next high.
Beautify

Traditional steel barrier are using gray tones, eye-catching warning and visual sensory were significantly less than on the new M-pc barrier in accordance with the overall planning and design, a variety of different colors, and the integration of landscape scenery of the road to allow motorists a feast for the eyes of the visual sense.

Security

The key barrier designed to cushion and a warning. When the vehicle hit the barrier, the two objects belong to the same metal material in the impact of the acceleration due to gravity, the shock generated by the energy shock of the third objects (cars were the best) are caused by human internal organs and shock injuries, and even a serious traffic accident, the consequences Concern. The new M-pc flexible body highly reflective steel barrier, toughness and ductility, in the time of the accident can give full play to the buffer effect, can effectively reduce the harm to people and cars. And 2 surface barrier embedded in high reflective ornaments, with road warning and guidance functions, increase traffic safety, better traffic at night.

To facilitate construction

Engineering plastic light weight, only the steel 1 / 8 weight, generally because of the weight of heavy steel barrier, the construction of the need to force people to operate, the more difficult construction and high-risk, flexible and reflective light barrier, coupled with mounting card Construction easier, reduce staff, efficiency as high as 5 to 10 times lower construction costs and so on a number of advantages.

Comprehen sive reviews Ontology steel has excellent toughness and vehicles after the impact can be absorbed most of the impact energy, rebound effect caused by difficult, the barrier will enable the body and vehicle and personnel by the best Security. As a result of too much easy to produce elastic rebound effect caused more casualties. Conservation is not easy because the utilization rate of a year is too short for the conservation and the depletion of the human cost. Body with too much steel and cause the vehicle after the crash fatal car crash. With steel body and lack of toughness, after the vehicle hit into the cause of the driveway or into the slope. Have a good body and the toughness of steel, but Ontology area is too small, inadequate protection. Ontology good mix of steel and toughness, but too small protective effect of blade cause even greater casualties.
