Global contractors always focus on guardrail service life and warranty. Standard export-grade wave guardrails can serve 15–20 years with low maintenance, while low-quality guardrails rust and fail within only 2–3 years.
1. High-quality Steel Base
We use pure Q235B / Q355B steel with stable toughness and strong impact resistance. No recycled steel. The steel structure remains stable under long-term sunshine, temperature change and outdoor exposure.
2. Professional Galvanizing Standard
550g/㎡ zinc coating: 10–12 years service life for inland areas
1100g/㎡ high zinc coating: 18–20 years service life for coastal salt spray areas
The hot-dip galvanized layer has self-repairing ability to prevent continuous rust expansion.
3. Precise Export Production Process
Strict control on beam flatness, radian and punching accuracy ensures stable overall structure and uniform stress bearing after installation.
Our export guardrails comply with international project standards, providing long-term safety performance and reducing road maintenance costs for global infrastructure projects.
