Product Introduction
| Galvanized Steel Wire Technical Specifications | |
| Specification | Details |
| Common Grades & Base Material | Low Carbon Steel (e.g., 1008, 1010, 1018): Standard grade for general-purpose wire. High Carbon Steel (e.g., 1065, 1075, 1080): For spring wire and high-strength applications. Alloy Steel (e.g., 4140): For special high-strength, fatigue-resistant applications. Stainless Steel (Type 302/304, galvanized rare): Base material may be galvanized for extra corrosion protection in specific cases. |
| Galvanizing Process & Type | Hot-Dip Galvanized (HDG): Wire drawn, then immersed in molten zinc bath. Thicker, less uniform coating. Electro-Galvanized (EG): Zinc electroplated onto wire. Thin, smooth, uniform coating, excellent for forming. Galvanized Before Drawing (GBD / Drawn Galvanized): Heavy zinc coat applied to rod, then drawn to final size for a smooth, integrated coating. Galvanized After Drawing (GAD): Wire drawn to size, then galvanized; more common for general-purpose wire. |
| Tensile Strength & Temper | Soft (Annealed) Galvanized: Low tensile (~350-550 MPa), high ductility, for weaving, tying, forming. Hard Drawn Galvanized: High tensile (~1000-1400 MPa), low elongation, for structural, spring, and prestressing applications. Medium Hard / Half Hard: Intermediate properties for balance of strength and formability. Extra High Tensile (EHT): > 1400 MPa, for critical structural components. |
| Diameter / Gauge Range | Ultra-Fine Wire: 0.10 mm (0.004") to 0.50 mm (0.020") Fine Wire: 0.50 mm (0.020") to 2.00 mm (0.079") Standard Wire: 2.00 mm (0.079") to 5.00 mm (0.197") Heavy Wire: 5.00 mm (0.197") to 10.00 mm (0.394") Rod / Rebar Tie Wire: Typically 1.6 mm (16 gauge / 0.0625") is common. |
| Coating Properties & Weight | Coating Mass (Typical HDG): 30-150 g/m² (varies with diameter and process). Coating Class (ASTM A641): Class 1, 2, 3 (increasing coating thickness). Coating Adherence: Wrapping test per standard (e.g., wrap wire around mandrel 4x its diameter). Surface Finish: Bright (EG), spangled gray (HDG), or dull gray (GBD). |
| Packaging & Form | Coils: Bulk coils (25-1000 kg) for industrial processing. Spools/Reels: Small spools (1-25 kg) for retail, construction, or automated feeding. Straightened & Cut Lengths: Pre-cut wires for specific applications (e.g., fence staples, hooks). Bales: For very heavy gauge wire. |
| Key Mechanical Properties (Hard Drawn, Example) | Tensile Strength: 1000-1400 MPa (varies with diameter). Yield Strength (0.7% Extension): Often ~80-90% of tensile. Elongation: Typically 3-8% in 250mm for hard drawn. Wrap Test: Mandrel diameter = 4x wire diameter, coating must not flake off. |
| Standard Specifications | ASTM A641/A641M: Standard Specification for Zinc–Coated (Galvanized) Carbon Steel Wire. ASTM A853: Galvanized Steel Wire Strand. ASTM B498/B498M: Galvanized Steel Wire for Mechanical Springs. EN 10244-2: Steel wire and wire products - Non-ferrous metallic coatings on steel wire. |
| Fabrication & Performance | Formability: Soft galvanized wire excellent; hard drawn limited to simple bends. Weldability: Not recommended; zinc fumes are hazardous and coating is destroyed at weld. Corrosion Resistance: Sacrificial protection from zinc; life depends on coating mass and environment. Fatigue Resistance: Moderate; coating can sometimes introduce notch sensitivity. |
| Primary Applications | Construction: Rebar tying, stucco/netting, suspension cables, prestressed concrete strands. Fencing & Agriculture: Chain link fence, barbed wire, vineyard/trellis wire, baling twine core. Industrial: Wire rope/cable core, mesh, springs (e.g., mattress), hardware cloth, nails/staples. Utilities & Communications: Guy wires, messenger strand, binding/bundling wire. General Use: Craft wire, hanging wire, general binding/tying. |
