Wholesale PVC Coated Wire Mesh Fencing

PVC coated wire mesh fencing consists of a steel wire core that is uniformly extruded with a polyvinyl chloride layer. The coating provides a barrier against corrosion while maintaining the mechanical properties of the underlying wire. This product is supplied in roll or panel form for large‑scale perimeter, security, and agricultural applications.

Material Composition and Coating Process

The core wire is typically low‑carbon steel with a tensile strength ranging from 350 MPa to 550 MPa, depending on the gauge selected. Prior to coating, the wire undergoes a hot‑dip galvanizing or zinc‑aluminum treatment to achieve a minimum zinc coating mass of 50 g/m². The PVC extrusion is performed at temperatures between 180 °C and 210 °C, resulting in a coating thickness of 0.3 mm to 0.8 mm measured on the wire diameter.

Coating adhesion is verified by a cross‑cut test according to ASTM D3359, with acceptable results showing no delamination under 500 g load. The PVC formulation includes UV stabilizers and impact modifiers to limit embrittlement under prolonged sunlight exposure.

Typical Specifications

Parameter	Typical Range	Notes
Wire diameter (core)	1.2 mm – 4.0 mm	Custom diameters available
Mesh opening (square)	10 mm – 100 mm	Rectangular options on request
PVC coating thickness	0.3 mm – 0.8 mm	Measured over wire diameter
Roll width	0.5 m – 3.0 m	Standard lengths 20 m – 50 m
Tensile strength of coated wire	300 MPa – 500 MPa	Dependent on core gauge

Mechanical Performance Characteristics

The PVC layer adds a modest increase in flexural rigidity, typically raising the bending modulus by 5 %–10 % compared with bare galvanized wire. Impact resistance, measured by a falling‑weight test (ASTM D2444), shows no cracking at energies up to 2 J for 2 mm diameter wire with 0.5 mm coating.

Corrosion resistance is evaluated via salt‑spray exposure (ASTM B117). Samples with the described zinc‑aluminum pre‑treatment and PVC coating exhibit less than 5 % red rust after 500 hours, indicating suitability for coastal or industrial atmospheres.

Applications in Industrial Settings

In manufacturing facilities, the fencing serves as a perimeter barrier that prevents unauthorized access while allowing visibility for safety monitoring. The non‑conductive PVC surface reduces the risk of accidental electrical contact when installed near live equipment.

Agricultural operations use the mesh to contain livestock and protect crops from wildlife. The coating’s resistance to urea‑based fertilizers and pesticides extends service life compared with untreated galvanized mesh.

Transport and logistics centers adopt the product for securing storage yards and separating hazardous zones. The smooth PVC finish minimizes snagging of straps and tarps during loading operations.

Quality Assurance and Testing

Each production lot undergoes dimensional verification using laser micrometers, with tolerances of ±0.05 mm for wire diameter and ±2 mm for mesh pitch. Visual inspection follows ISO 9001‑guided procedures to detect coating defects such as pinholes or thin spots.

Mechanical samples are pulled to failure in a universal testing machine; results are recorded and compared against the specified tensile range. Batch‑to‑batch variation is kept under 8 % for tensile strength and under 10 % for elongation at break.

Customization Options

• Alternative core materials: stainless steel grades 304 or 316 for enhanced corrosion resistance.
• Color pigments integrated into the PVC extrusion (e.g., green, blue, black) for site‑specific identification.
• Co‑extruded layers with antimicrobial additives for food‑processing environments.
• Custom roll lengths and widths to match on‑site installation constraints.
• Perimeter framing kits with pre‑drilled posts and tensioning hardware.

Frequently Asked Questions
