Highway Impact Energy Absorption Safety Rolling Guardrail Sage
Roller Barrier
Roller Barrier Introduction
Concrete barriers and conventional metal guardrail system are
effective, but cause major damage to the impacting vehicle and the
guardrail itself. Now a new type barrier system called
energy-absorption roller barrier system, invented by Qingdao
Taicheng Transportation Facilities Co., Ltd, subsidiary of Qingdao
Henger Marine Supply Co., Ltd, that specializes in highway safe
guardrail systems for years in China, rises in response to bringing
innovation technology to road safety, reducing death rate in
traffic accident higher than 90% compared to traditional
guardrails.
Roller Barrier Material
energy-absorption roller, core part of the roller barrier system,
is made of EVA polyurethane. The EVA polyurethane is a new type
high molecular synthetic material that equips outstanding features
of plastic and rubber. It has the high strength of plastic and high
elasticity of rubber. The special characteristics of EVA
polyurethane make itself to be an ideal material for endoenergic
roller than EVA polyethylene.
Product Feature
1. better abrasion performance than polyethylene material roller
2. Higher acid and alkali resistance, better impact resistance,
better flammability than polyethylene material roller
3. a wide range of options on size, color and appearance design
4. Modular design to save installation cost and installation time,
safety and no pollution.
5. Lower maintenance cost
6. landscaping design for environmental purposes
