Black Galvanized Chain Link Fence – Supplier from China
Black galvanized chain link fence combines a steel wire core with a zinc‑galvanized layer and a black polyvinyl chloride (PVC) overcoat. The dual‑layer protection provides corrosion resistance while the black finish offers a low‑visibility aesthetic suitable for security perimeters, sports enclosures, and agricultural boundaries.
Materials and Construction
The fence fabric is formed from cold‑drawn steel wire, typically ranging from 2.0 mm to 4.0 mm diameter depending on the required tensile strength. Prior to coating, the wire undergoes hot‑dip galvanizing, achieving a zinc coating weight of 180 g/m² to 270 g/m² per ASTM A123. After galvanizing, a black PVC extrusion is applied, adding a uniform thickness of 0.3 mm to 0.5 mm and providing UV‑stabilized colorfastness.
| Parameter | Typical Range / Value | Notes |
|---|---|---|
| Wire diameter | 2.0 mm – 4.0 mm | Selected based on load requirements |
| Zinc coating weight | 180 g/m² – 270 g/m² | Hot‑dip galvanized per ASTM A123 |
| PVC overcoat thickness | 0.3 mm – 0.5 mm | Black, UV‑stabilized |
| Mesh opening (square) | 50 mm × 50 mm – 100 mm × 100 mm | Customizable per project |
| Fence height | 1.0 m – 3.0 m | Posts spaced 2.5 m – 3.0 m |
| Tensile strength of wire | ≥ 350 MPa | Cold‑drawn steel |
Typical Applications
In perimeter security, the black PVC overcoat reduces visual glare and helps the fence blend with surrounding vegetation, making it less conspicuous to intruders while maintaining a clear barrier.
For sports facilities such as tennis courts or baseball fields, the smooth PVC surface minimizes abrasion to players and equipment, and the zinc‑galvanized core prevents rust from sweat and rain exposure.
Agricultural enclosures benefit from the corrosion‑resistant coating, which withstands exposure to fertilizers, animal waste, and fluctuating humidity, extending service life beyond that of plain‑steel alternatives.
Quality Control and Testing
Each production lot undergoes coil‑to‑coil zinc coating thickness measurement using magnetic induction probes, with acceptance limits set at ±10 % of the target weight.
PVC adhesion is verified by a cross‑hatch test per ASTM D3359, requiring no coating removal after 50 cycles of abrasion.
Tensile samples are pulled to failure; results must exceed 350 MPa to be released for shipment.
Customization Options
- Wire diameter: 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm
- Mesh opening: 50 mm, 75 mm, 100 mm square (custom sizes on request)
- Fence height: 1.0 m to 3.0 m in 0.5 m increments
- Post type: round steel pipe, square tube, or concrete‑set anchors
- Coating color: standard black, dark green, or custom RAL shades
Packaging and Shipping
Finished rolls are wrapped in polyethylene shrink film to protect the PVC surface from scratches during handling.
Each roll is placed on a wooden pallet, secured with steel straps, and labeled with product code, length, and weight.
For export, pallets are loaded into 20‑ft or 40‑ft containers with moisture‑absorbent desiccants and subjected to a final container inspection before sealing.
Frequently Asked Questions
- Can the fence dimensions be customized?
- Yes, wire diameter, mesh opening, height, and post configuration can be adjusted to meet project specifications.
- What information is required for a quotation?
- Required details include desired height, length, wire gauge, mesh size, coating preference, and any special post or gate requirements.
- How is quality inspected before shipment?
- Quality control includes coating thickness measurement, adhesion testing, tensile strength verification, and visual inspection of the PVC overcoat.
- What packaging methods are available for export?
- Standard export packaging uses polyethylene film wrap, wooden pallets, steel strapping, and container desiccants; alternative crating can be arranged upon request.
