Electro-galvanized steel wire is a premium low-carbon or medium-carbon steel wire coated with a thin layer of zinc using electroplating. This process provides excellent corrosion resistance and a smooth, bright surface finish. Electro-galvanized steel wire is particularly suitable for applications that require precise dimensional control and high surface quality. By choosing different passivation processes, it can meet diverse demands ranging from industrial to consumer products. It is recommended that special food-grade passivation treatment be adopted for medical and food contact applications.
At Jiangsu Cunrui Metal Products Co., Ltd., we produce high-quality electro-galvanized steel wire with uniform coating, stable mechanical properties, and flexible specifications tailored to various industrial needs.
Product Advantages:
Excellent Corrosion Resistance: Uniform zinc coating prevents rust in dry, indoor, and mildly humid environments
Smooth and Bright Surface: Ideal for decorative or visible wire uses
High Ductility and Flexibility: Easy to form, twist, and weld
Stable Mechanical Strength: Suitable for tensile and load-bearing uses
Eco-Friendly Electroplating: Non-toxic, RoHS-compliant processes

Galvanized Steel Wire Technology Description:
1. Material Basic Properties
Definitions and Standards
Process type: Electro-galvanizing
International standards:
ISO 7989-2 (Electro-galvanized steel wire)
ASTM A641 (Class 3 electro-galvanized)
Chinese standard: GB/T 15393-2020
2. Key Features
Uniform coating: Thickness adjustable (5 - 30 μm)
Smooth surface: Ra ≤ 0.8 μm (better than hot-dip galvanizing)
No hydrogen embrittlement risk: Utilizes special post-treatment process Colorless plating: Satisfies aesthetic requirements
3. Performance Comparison (vs Galvanizing)
Characteristics Electro-galvanizing Galvanizing
Layer Uniformity ±1μm (Precisely controlled) ±15μm (High fluctuation)
Surface Roughness Ra ≤ 0.8μm Ra ≥ 2.5μm
Layer Adhesion Mechanical interlocking + Electrochemical bonding Metallurgical bonding
Suitable Wire Diameter φ0.1 - 5.0mm φ 2.0mm and above are more cost-effective
Hydrocracking Risk Requires strict hydrogen removal Almost no risk
