Why Choose Our Galfan Steel Strands?
​Engineered for ultimate durability, our Galfan Steel Strands feature a high-purity zinc-aluminum mischmetal alloy coating (typically 5% Al, 95% Zn). Compared to traditional galvanized steel, Galfan offers 2 to 3 times superior corrosion resistance, making it the premier choice for critical infrastructure, cable-stayed bridges, marine environments, and high-load structural applications.
Premium Galfan Steel Strand High-Performance Corrosion-Resistant Wire Solutions
· ​Exceptional Corrosion Resistance: The unique Zn-Al-Mm eutectic structure forms a dense, stable passive film that actively prevents rust and atmospheric degradation.
· ​Superior Ductility & Adhesion: The coating tightly bonds to the high-carbon steel wire base, ensuring it won't peel or flake during severe bending, twisting, or stranding processes.
· ​Sacrificial & Barrier Protection: Combines the galvanic sacrificial protection of zinc with the long-term barrier durability of aluminum.
· ​Extended Lifespan: Significantly lowers maintenance costs and lifecycle replacement frequency for structural engineering projects.
· ​High Tensile Strength: Manufactured from premium high-carbon steel wire rod, offering exceptional load-bearing capacity and structural integrity.
