Galvanized barbed wire fence rolls consist of low‑carbon steel strands twisted together, with uniformly spaced barbs formed by cutting and pressing the wire. The entire assembly is hot‑dip galvanized to a coating weight that meets ASTM A123 standards, providing a barrier against atmospheric corrosion for outdoor perimeter applications.
Technical Specifications
| Parameter | Typical Value | Reference Standard |
|---|---|---|
| Core Wire Diameter | 2.0 mm – 2.8 mm (customizable) | ASTM A641 |
| Galvanizing Coating Weight | 150 g/m² – 275 g/m² (hot‑dip) | ASTM A123 |
| Barb Spacing | 75 mm – 150 mm (adjustable) | Manufacturer’s spec |
| Roll Length | 50 m – 200 m (standard 100 m) | Customer requirement |
| Tensile Strength (wire) | 350 MPa – 550 MPa (depends on grade) | ASTM A370 |
The wire is drawn from low‑carbon steel billets, then twisted into a double‑strand core. Barbs are created by cutting a length of wire, bending it into a sharp point, and pressing it onto the core at the specified spacing. After barb formation, the entire roll passes through a molten zinc bath at approximately 450 °C, forming a metallurgical bond that yields the coating weight listed above.
Applications
In perimeter security, the sharp barbs deter climbing and cutting attempts, while the galvanized coating maintains structural integrity in humid, saline, or industrial atmospheres. Livestock operations use the same product to contain animals because the barbs discourage pressure against the fence without causing injury when properly tensioned. Industrial facilities select galvanized barbed wire for its low maintenance cost over a 15‑ to 20‑year service life in outdoor environments.
Quality Control Philosophy
Each production lot undergoes three checkpoints: (1) wire diameter and tensile strength verified with a calibrated tensile tester; (2) coating thickness measured by magnetic induction probe to ensure compliance with the ordered g/m²; (3) barb sharpness and spacing inspected optically to confirm that barbs meet the specified geometry and are free of burrs that could compromise coating adhesion.
Customization Options
- Wire diameter: 1.8 mm to 3.2 mm
- Galvanizing coating: 100 g/m² to 350 g/m² (hot‑dip or electro‑galvanized)
- Barb spacing: 50 mm to 200 mm
- Roll length: 25 m to 300 m
- Tensile grade: low‑carbon, medium‑carbon, high‑strength alloy
Packaging and Shipping
Finished rolls are wound onto a cardboard core, wrapped in UV‑stabilized polyethylene film, and placed on wooden pallets with corner protectors. A vapor‑corrosion inhibitor (VCI) sheet is added inside the wrap to guard against moisture during transit. Pallets are strapped with polyester bands and loaded into 20‑ft or 40‑ft containers according to customer volume.
Frequently Asked Questions
Can the wire diameter and coating weight be adjusted for a specific project?
Yes. Both parameters are defined during the quotation stage based on the mechanical load and corrosion exposure you specify.
What information do you need to provide an accurate quote?
Required details include desired wire gauge, coating weight (g/m²), barb spacing, roll length, tensile grade, and delivery destination.
How is the galvanizing quality verified before shipment?
We perform coil‑coating thickness tests on a sample from each batch and provide a mill test report with the shipment.
What are the standard lead times for a factory‑direct order?
Typical production time is 10‑15 working days after receipt of the signed purchase order, excluding transit.
