PVC coated welded wire fence consists of low-carbon steel wires that are electrically welded at each intersection and then extruded with a uniform polyvinyl chloride (PVC) coating. The coating provides a barrier against moisture, chemicals, and UV exposure while maintaining the structural integrity of the welded mesh.
The base wire is typically drawn to diameters ranging from 1.2 mm to 4.0 mm, depending on the required load-bearing capacity. After welding, the mesh passes through a PVC extrusion line where the coating thickness is controlled between 0.3 mm and 0.8 mm. This dual-layer protection combines the tensile strength of steel with the corrosion resistance of PVC.
Unlike plain galvanized wire, the PVC layer prevents direct contact between the steel and corrosive agents, significantly extending service life in aggressive environments such as fertilizer storage or marine peripheries. The coating also reduces the risk of injury from sharp wire ends during installation.
Key Technical Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Wire Diameter | 1.2–4.0 mm | Customizable per load requirements |
| Mesh Opening | 12.5–100 mm | Square or rectangular options |
| PVC Coating Thickness | 0.3–0.8 mm | Uniform extrusion |
| Tensile Strength of Steel Wire | 350–550 MPa | Depends on wire grade |
| Roll Width | 0.5–3.0 m | Standard widths available |
| Roll Length | 10–50 m | Length adjusted to project needs |
| Weight per Unit Area | 2.5–8.0 kg/m² | Influenced by diameter and coating |
Material and Coating Properties
The steel core undergoes a cold-drawing process to achieve consistent tensile properties before welding. Prior to PVC application, the welded mesh is often pre-treated with a zinc-rich primer to enhance adhesion and provide an additional corrosion barrier. The PVC compound used is formulated with UV stabilizers and impact modifiers to resist embrittlement under prolonged sunlight.
Applications and Why They Fit
Agricultural operations use PVC coated welded wire fence to contain livestock while resisting degradation from fertilizers, animal waste, and irrigation chemicals. In industrial settings, the fence serves as a perimeter barrier that withstands exposure to oils, solvents, and abrasive particles without coating delamination. Municipal projects specify the product for park enclosures and pedestrian pathways where public safety and low maintenance are priorities. The smooth PVC surface also reduces snagging hazards compared to bare wire alternatives.
- Livestock pens and pasture boundaries
- Crop protection enclosures
- Industrial facility perimeter fencing
- Waste treatment plant barriers
- Sports field and playground fencing
Customization Options
Wire diameter can be selected from 1.2 mm to 4.0 mm to match required impact resistance and wind load calculations. Mesh aperture is adjustable between 12.5 mm and 100 mm, allowing fine mesh for small animal containment or larger openings for visibility and airflow. PVC coating color is available in standard hues such as green, black, white, and gray, with custom colors achievable upon request.
- Wire diameter (1.2–4.0 mm)
- Mesh opening (12.5–100 mm)
- PVC coating thickness (0.3–0.8 mm)
- Coating color (standard RAL options)
- Roll width and length
Quality Control and Testing
Each production line incorporates inline weld inspection using magnetic flux leakage to detect incomplete fusions before coating. After extrusion, coating adhesion is measured by peel test according to ASTM D903, with a minimum threshold of 1.5 N/mm required for release. Tensile samples are taken from both wire and coated composite to verify that the PVC layer does not compromise the base steel strength. Finally, a salt spray chamber test (ASTM B117) evaluates corrosion resistance, with a typical target of 1,000 hours without red rust.
Packaging and Shipping
Finished rolls are wrapped in shrink‑film to protect the PVC surface from abrasion during handling, then placed on wooden pallets with corner protectors. Pallets are strapped and stretch‑wrapped to prevent shifting inside containers, and each roll is labeled with product code, dimensions, and batch number for traceability. For overseas shipments, desiccant packets are included to control humidity inside the packaging.
| Packaging Method | Description | Typical Use |
|---|---|---|
| Shrink‑film + Pallet | Roll wrapped in PE shrink‑film, placed on wooden pallet with corner guards | Domestic truckload shipments |
| Stretch‑wrapped Pallet | Pallet secured with stretch film and straps | Containerized export |
| Desiccant Pack | Silica gel packets placed inside packaging | Long‑term sea freight |
