Compared with traditional guardrails, polymer flexible guardrails have some significant differences and innovative designs, which mainly involve materials, structures and properties
Material properties: Polymer materials: Polymer flexible guardrails are usually made of flexible polymer materials, such as polyethylene, polyvinyl chloride, etc. These materials have good elasticity and weather resistance, and are able to quickly return to their original shape after being stressed.
Traditional materials: Traditional guardrails are usually made of metal materials, such as steel or aluminum alloys. These materials are relatively rigid and can deform or break when subjected to stress.
Structural design: Flexible design: Polymer flexible guardrails are often designed as soft, retractable structures that can absorb and disperse crash forces, thereby reducing the impact on vehicles and passengers.
Rigid design: Traditional guardrails usually have a more rigid structure, which can cause greater impact to the vehicle and passengers in the event of a collision.
Safety performance: reduce the collision force: the polymer flexible guardrail can reduce the impact on the vehicle and passengers during the collision through its soft characteristics, and reduce the accident injury.
Limitations of rigid guardrails: Traditional guardrails can cause more damage to vehicles and passengers in the event of a crash, especially in scenarios such as highways.
Installation & Maintenance:
Easy to install and maintain: Polymer flexible guardrails are usually relatively lightweight, making them easy to install and maintain. Some designs can even be quickly disassembled and replaced.
More complex installation: Traditional guardrails may require a more complex installation process and may require more manpower and resources in terms of maintenance.
Aesthetics: Appearance design: Polymer flexible guardrail is more flexible in design, and can adopt various colors and shapes to adapt to different scenes and environments.
Consistency of traditional guardrails: Traditional guardrails often have a relatively consistent appearance and may be slightly singular in terms of aesthetics.
Overall, the polymer flexible guardrail provides better crash energy absorption performance through the innovative design of its materials and structure, and is more suitable for modern traffic and safety needs. However, specific use cases and requirements need to be considered when making specific choices.
