Product Overview
Our Zinc-Aluminum Alloy Coated Steel Wire (also called Zn-10%Al-RE Alloy Coated Wire) combines the strength of high-carbon steel with advanced corrosion protection. Ideal for harsh environments, this wire features a 230–350g/m² zinc-aluminum coating-3–5x more durable than standard galvanized wire-ensuring decades of service life even in coastal or industrial areas.
Key Advantages vs. Ordinary Galvanized Wire:
✔ Longer Lifespan: 50+ years in rural, 25–30 years in coastal/salty air (per ISO 9224 accelerated corrosion tests).
✔ Higher Tensile Strength: 400-1300N/mm² (adjustable to meet ASTM A641, EN 10244-2 standards).
✔ Eco-Friendly: Uses 10% aluminum + rare earth elements to reduce zinc consumption by 15% while enhancing adhesion.
