FAQ
1. What does “low deformation” mean in this guardrail system?
Low deformation refers to the guardrail’s ability to undergo minimal bending or movement upon impact, ensuring that it retains structural integrity and provides stronger containment for vehicles.
2. Can this guardrail system be used on curves and slopes?
Yes, the guardrails are designed for challenging road geometries, including curves and embankments, and can be tailored in span, height, and anchorage to suit specific terrain conditions.
3. How long can I expect this guardrail to last under normal highway service?
With appropriate installation and maintenance, the system is engineered for a service life of 20 – 30 years, even under heavy traffic and harsh environmental exposure.
4. How does this system enhance highway safety compared to standard guardrails?
By combining high‑strength materials and low‑deformation design, this guardrail system offers better energy absorption, higher resilience in collisions, and improved stability—especially important on high‑speed roads or freight corridors.
5. What kind of maintenance is required?
Routine inspections are recommended to check anchorage, fastener integrity, and coating condition. Minor corrective actions (like tightening bolts or replacing damaged posts) help maintain optimal performance with minimal disruption.
