Hot-dip Zinc (zinc-aluminium or zinc-aluminium-magnesium) Coated Steel Wires for Bridge Cables
Hot-dip galvanized steel wires for bridge cables are made of high carbon steel wire rods and have the characteristics of high tensile strength, low relaxation, steady modulus of elasticity, great linearity, and strong resistance to corrosion through continuous drawing, hot- dip galvanization (with aluminum or magnesium), and stabilization treatment. Hot-dip galvanized steel wires are primarily used in the main cables of large-span suspension bridges, stay cables of cable-stayed bridges, and external reinforcement cables of various buildings and structures.
