Basic Parameters of Galvanized Steel Wire
| Parameter Category | Specific Parameter | Description / Common Specifications | Remarks |
|---|---|---|---|
| Core Material | Base Steel | Low-carbon steel wire rod, such as Q195, Q215, SAE1006. | Ensures good ductility, toughness, and drawability. |
| Coating Type | Electro-Galvanized (EG/ EZ) | Thin zinc coating (typically 8-20 g/m²). Smooth, bright, shiny surface. Moderate corrosion resistance. Lower cost. | Suitable for indoor, dry environments, or short-term rust prevention. Used for binding, crafts, general goods. |
| Hot-Dip Galvanized (HDG/ GALV) | Thick zinc coating (typically 30-300 g/m²). Surface has spangle pattern, slightly rough. Excellent corrosion resistance and adhesion. | The standard for outdoor, construction, fencing, and agricultural applications in corrosive environments. | |
| Dimensional Specs | Wire Diameter | Unit: Millimeters (mm) Common Range: 0.2mm ~ 6.0mm Notation: 1. Direct mm value (e.g., 2.0mm). 2. SWG (Imperial) or BWG (Birmingham Gauge). Larger gauge number = thinner wire. |
The most critical specification, determining thickness and strength. Always clarify the unit when ordering. |
| Length | Typically supplied in coils. Common coil weights: 25kg or 50kg. Length varies with diameter. | Can be custom cut to length (straight lengths) upon request, but less common. | |
| Mechanical Properties | Tensile Strength | General Purpose: 300-500 MPa High Tensile: Can exceed 1000 MPa |
Depends on material grade and degree of work hardening (drawing). |
| Elongation | Typically ≥ 10% (e.g., δ₁₀) | Indicates the ductility and ability to deform plastically. |
Benefits of Galvanized Steel Wire
1. Superior Corrosion Resistance & Extended Service Life
- Direct Value: Cost Savings & Reduced Maintenance
The zinc coating, especially the hot-dip variety, provides both active and passive protection
This means: Your product (e.g., fence, cage, structural part) enjoys a significantly longer lifespan in outdoor, humid, or mildly corrosive environments. It eliminates the need for frequent replacement, dramatically reducing long-term material costs and maintenance labor, achieving a "one-time investment, long-term use" benefit.
2. Excellent Balance of Strength and Ductility
- Direct Value: Safe, Reliable & Easy to Process
This means: Your construction or manufacturing process becomes more convenient and efficient, with lower processing difficulty and rejection rates, while ensuring the final product is robust and secure.
3. Consistent Performance & Uniform Surface
- Direct Value: Predictable Quality & Neat Appearance
This means:
For Buyers/Traders: Guarantees consistent quality with every shipment, simplifying inventory management and cost accounting, and enhancing your supply chain reliability.
For End-Users: The finished products (e.g., mesh, crafts) have a more uniform and professional appearance, improving overall product quality. For critical uses (e.g., cable armoring), consistent performance is fundamental to safety.
Three Core Advantages of Choosing Us
FAQ
1. Q: What is the main difference between Electro-Galvanized (EG) and Hot-Dip Galvanized (HDG) wire?
A: The key differences are in the coating process, thickness, and appearance:
EG: Thin, bright, uniform coating (8-20 g/m²). Suitable for indoor/general use.
HDG: Thick, durable coating with a spangled finish (30-300 g/m²). Ideal for outdoor/corrosive environments.
2. Q: How do I choose the right zinc coating weight for my application?
A: It depends on the environment and required service life:
Light duty (Indoor): 8-40 g/m² (EG or light HDG)
General outdoor: 60-120 g/m² (HDG)
Marine/Harsh industrial: 120-300 g/m² (Heavy HDG)
