Key Advantages of Galvanized Coating for Gabion Mesh

Key Advantages of Galvanized Coating for Gabion Mesh

1. Superior Corrosion Resistance

• Zinc Barrier: Forms a dense protective layer (typically 60-300g/m²) to block moisture, oxygen, and chemicals.
• Sacrificial Protection: Even if scratched, zinc corrodes first (electrochemical action), extending service life to 20-50 years (varies by environment).
• Performance: Outperforms bare steel by 3-5x in saline/coastal areas (e.g., ASTM A975 standards).

2. High Strength & Durability

• Tensile Integrity: Retains base steel strength (350-500MPa) post-coating, critical for load-bearing structures.
• Abrasion Resistance: Harder zinc layer reduces damage during handling/installation.

3. Cost-Effectiveness

• Low Lifetime Cost: Minimal maintenance vs. uncoated or PVC-coated alternatives (saves 30-50% long-term).
• Wide Availability: Galvanized wire is globally standardized, ensuring supply chain efficiency.

4. Sustainability & Compliance

• Recyclable: Fully reusable material aligns with circular economy (e.g., ISO 14001).
• Eco-Safe: No microplastic risks (unlike some polymer coatings).

5. Versatility

• Adaptability: Suitable for harsh environments (pH 6-12), from riverbanks to highway retaining walls.
