Custom Black PVC Coated Welded Wire Mesh
Product Overview
This mesh consists of low‑carbon steel wires welded at each intersection and then coated with a uniform layer of black PVC. The coating provides corrosion resistance, UV stability, and a non‑conductive surface suitable for outdoor and indoor installations.
Typical wire diameters range from 1.2 mm to 3.0 mm, and the welded joints maintain at least 95 % of the base wire tensile strength after coating.
Material & Construction
The core wire is produced from cold‑drawn SAE 1008/1010 steel, offering a yield strength of approximately 350 MPa. Welding is performed using resistance spot welding, creating a fused joint that prevents wire slippage under load.
After welding, the mesh passes through a PVC extrusion line where the coating thickness is controlled to 0.3 mm ± 0.05 mm on each side, resulting in a total added diameter of 0.6 mm.
The black pigment is UV‑stabilized, providing a minimum of 2000 hours of ASTM G154 weathering exposure without noticeable fading or cracking.
Technical Specifications
| Parameter | Typical Value | Customizable Range |
|---|---|---|
| Wire Diameter (core) | 2.0 mm | 1.2 mm – 3.0 mm |
| Aperture (opening) | 50 mm × 50 mm | 20 mm – 100 mm (square or rectangular) |
| Roll Width | 1.0 m | 0.5 m – 2.5 m |
| Roll Length | 25 m | 10 m – 50 m |
| PVC Coating Thickness (each side) | 0.30 mm | 0.20 mm – 0.50 mm |
| Tensile Strength of Wire (post‑coat) | ≥ 340 MPa | Depends on wire grade |
Customization Options
Buyers can specify wire diameter, aperture size, roll dimensions, and PVC coating thickness to match project requirements. Color options beyond black (e.g., green, gray) are available upon request, with the same UV‑stabilized formulation.
Additional treatments such as anti‑static additives or flame‑retardant PVC can be incorporated if the application demands specific safety standards.
- Wire diameter: 1.2 mm, 1.6 mm, 2.0 mm, 2.5 mm, 3.0 mm
- Aperture: square 20 mm–100 mm or rectangular combos
- Roll width: 0.5 m–2.5 m (in 0.1 m increments)
- Roll length: 10 m–50 m (custom lengths)
- PVC coating: 0.20 mm–0.50 mm per side
Typical Applications
The black PVC coating provides a barrier against moisture and chemicals, making the mesh suitable for permanent outdoor fencing where visual discretion is desired.
In concrete reinforcement, the coated mesh prevents direct contact between steel and alkaline environments, reducing the risk of corrosion‑induced spalling.
Agricultural uses include animal enclosures and crop protection, where the smooth coating limits injury to livestock and facilitates cleaning.
Industrial partitioning and machine guarding benefit from the non‑conductive surface, which reduces electrical hazards in environments with live equipment.
Quality Control Philosophy
Each production lot undergoes inline measurement of wire diameter using laser micrometers, with acceptance limits of ±0.02 mm.
PVC coating thickness is verified by non‑destructive magnetic induction probes at five points per square meter; the average must stay within the specified tolerance.
Adhesion of the coating to the steel is tested per ASTM D4541 (pull‑off method); a minimum adhesion strength of 1.5 MPa is required.
Final inspection includes visual examination for defects such as pinholes, bubbles, or uneven coloration, and a dimensional check of aperture tolerances (±2 mm).
Packaging & Shipping
Rolls are wound on sturdy cardboard cores with inner diameter 50 mm, then wrapped in polyethylene film to prevent moisture ingress during transit.
Each roll is placed on a pallet (max 20 rolls per pallet) and secured with strapping; corner protectors guard against impact damage.
For export, pallets are fitted with heat‑shrinkable pallet covers and labeled with handling instructions, ensuring compliance with ISPM‑15 wood‑packaging standards.
Frequently Asked Questions
Can dimensions be customized?
Yes. Wire diameter, aperture size, roll width, and length are all adjustable according to project specifications. Provide the required values and we will generate a quotation.
What information is needed for a quote?
We need the wire diameter, aperture dimensions, desired roll width and length, PVC coating thickness, and any additional treatments (e.g., flame retardant). Delivery destination helps calculate freight.
How is the PVC coating quality verified?
Coating thickness is measured with magnetic induction gauges; adhesion is tested via pull‑off method; and visual inspection checks for defects. Reports are available upon request.
What packaging options exist for overseas shipments?
Standard packaging includes polyethylene film wrapping, cardboard cores, palletization with strapping, corner protectors, and heat‑shrinkable pallet covers. Special packaging (e.g., wooden crates) can be arranged.
