Global contractors always focus on guardrail service life and warranty. Standard export-grade wave guardrails can serve 15\u201320 years with low maintenance, while low-quality guardrails rust and fail within only 2\u20133 years.<\/p>\n\n\n\n

1. High-quality Steel Base<\/strong><\/p>\n\n\n\n

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.<\/p>\n\n\n\n

2. Professional Galvanizing Standard<\/strong><\/p>\n\n\n\n

550g\/\u33a1 zinc coating: 10\u201312 years service life for inland areas
1100g\/\u33a1 high zinc coating: 18\u201320 years service life for coastal salt spray areas
The hot-dip galvanized layer has self-repairing ability to prevent continuous rust expansion.<\/p>\n\n\n\n

3. Precise Export Production Process<\/strong><\/p>\n\n\n\n

Strict control on beam flatness, radian and punching accuracy ensures stable overall structure and uniform stress bearing after installation.<\/p>\n\n\n\n
