Introduction
PVC coated wire is widely used in fencing, agriculture, construction, and industrial applications where additional protection against weathering and corrosion is required.
By combining galvanized steel wire with a durable PVC coating, the product offers both structural strength and enhanced service life.
What Is PVC Coated Wire?
PVC coated wire consists of:
Core Wire
Usually:
- Galvanized steel wire
- Low carbon steel wire
Outer Layer
A protective PVC (Polyvinyl Chloride) coating applied over the steel wire.
The coating acts as a barrier against:
- Moisture
- UV exposure
- Chemicals
- Abrasion
Manufacturing Process
Typical production steps:
- Steel wire drawing
- Galvanizing
- Surface preparation
- PVC extrusion coating
- Cooling
- Quality inspection
- Packaging
Typical Specifications
| Core Diameter | Finished Diameter |
|---|---|
| 1.6 mm | 2.0 mm |
| 2.0 mm | 3.0 mm |
| 2.5 mm | 3.5 mm |
| 3.0 mm | 4.0 mm |
Available Colors
Common colors include:
- Green
- Black
- Gray
- White
Green remains the most popular option for fencing applications.

| Corrosion Resistance | Excellent | Good |
| Appearance | Better | Standard |
| Color Options | Multiple | Metallic |
| UV Resistance | Better | Standard |
| Cost | Higher | Lower |
How to Specify PVC Coated Wire
Example:
Core Diameter: 2.5 mm
Finished Diameter: 3.5 mm
Core Material: Galvanized Steel
PVC Color: Green
Tensile Strength: 350–550 MPa
Conclusion
PVC coated wire offers an effective combination of strength, corrosion resistance, and visual appeal. It is widely used for fencing, agriculture, and outdoor infrastructure projects where long-term durability is important.
