Zinc-aluminum 10% Alloy Coated Steel Wire

Our Zinc-Aluminum 10% Alloy Coated Steel Wire represents the pinnacle of innovation in erosion control and retaining wall solutions. Manufactured from high-quality Q195 low-carbon steel and hot-dip coated with a unique Zn-10%Al-RE alloy (200-300g/m²), this wire delivers 2-3 times longer service life compared to conventional galvanized wire in aggressive environments. Certified to ASTM A856/A856M, EN 10244-2, and ISO 16120 standards, it is the preferred choice for critical infrastructure projects worldwide.

Technical Specifications & Competitive Advantages

---
