1. Product Overview
Steel wire is thin metal wire rod manufactured from hot rolled wire rod via pickling, phosphating, multi-pass cold drawing, heat treatment and surface coating deep processing. Round cross-section is mainstream, flat, square and special-shaped wires are available. It is divided into four major series: low carbon steel wire, medium carbon steel wire, high carbon spring steel wire and stainless steel wire, matched with black annealed, electro-galvanized, hot-dip galvanized, zinc-aluminum-magnesium alloy, PVC coated surface treatments. Complete grades of toughness, strength and corrosion resistance cover wide applications including construction binding, wire mesh, springs, prestressed components, baling, fences, mechanical fittings and cable armoring.
2. Core Product Advantages
Ultra-tight Dimensional Tolerance & Smooth SurfaceMulti-die continuous cold drawing ensures strict diameter tolerance, scratch-free, peeling-free and oxide-free surface, suitable for direct bending, weaving and spring coiling without secondary polishing.
Complete Mechanical Grades for All Working ConditionsLow carbon wire features soft bendability; medium carbon wire balances strength & weldability; high carbon spring wire delivers high tensile strength & stable resilience; stainless steel wire provides acid & alkali resistance to cover all scenarios.
Full Anti-corrosion System for Long Service LifeElectro-galvanized, hot-dip galvanized, Galfan zinc-aluminum-magnesium and PVC multi-layer coating options match inland, coastal high salt spray and chemical corrosive environments.
Excellent Machinability for Deep ProcessingSupports cutting, straightening, bending, weaving, stamping, welding and spring coiling, ideal raw material for wire mesh, animal cages, construction binding wire and prestressed steel strand.
Flexible Packaging for Easy Export LoadingSmall coils, large coils, wooden spools and straight cut lengths available, strapped with steel strips and wrapped by waterproof film to avoid rust & scattering during sea transportation.
Pure Chemical Composition & Stable Batch PerformanceRaw wire rod strictly controls harmful impurities S & P, stable annealing & tempering process with small fluctuation of tensile & elongation in same batch, full set of test reports attached.
