China Durable Double Barbed Wire Supplier
Double barbed wire consists of two parallel strands of high‑tensile steel wire, each equipped with uniformly spaced barbs that interlock when tensioned. This configuration provides increased resistance to cutting and climbing compared with single‑strand designs, making it suitable for perimeter security in industrial, agricultural, and infrastructure projects.
Technical Specifications
The following table lists typical values for the double barbed wire offered. Actual dimensions can be adjusted to meet project‑specific load and environmental requirements.
| Parameter | Typical Value | Notes |
|---|---|---|
| Core wire diameter | 2.0 mm – 3.0 mm | High‑carbon steel, cold‑drawn |
| Barb length | 15 mm – 20 mm | Sharp, uniformly spaced |
| Barb spacing | 75 mm – 150 mm | Adjustable per order |
| Tensile strength | ≥ 1 200 MPa | Measured per ISO 6935‑2 |
| Coating | Hot‑dip galvanized (Zn ≥ 200 g/m²) or PVC‑coated | Corrosion resistance for outdoor use |
| Roll length | 50 m – 200 m | Standard roll; custom lengths available |
Material Options
The core wire is produced from high‑carbon steel (C ≈ 0.6 %–0.8 %). Depending on the service environment, the wire can be supplied with:
- Hot‑dip galvanized coating (Zn ≥ 200 g/m²) for standard outdoor exposure.
- PVC coating (thickness 0.3 mm–0.5 mm) in colors such as green, black, or yellow for aesthetic or additional corrosion protection.
- Stainless‑steel core (AISI 304) for highly corrosive or marine environments, available upon request.
Applications and Functional Benefits
Because the double‑strand configuration distributes load across two wires, the system exhibits higher shear resistance. This makes it effective where a single strand could be cut with bolt cutters or climbed using handholds.
- Perimeter fencing for factories, warehouses, and logistics centers.
- Security barriers around power substations, water treatment plants, and telecommunications sites.
- Agricultural enclosures requiring livestock containment and predator deterrence.
- Temporary construction site protection where rapid deployment and re‑tensioning are needed.
Quality Control Philosophy
Each production lot undergoes tensile testing on a sample of the core wire, barb‑pull testing to verify anchorage, and coating thickness measurement using magnetic induction. Visual inspection checks for uniform barb spacing and absence of defects such as nicks or uneven coating.
Customization Options
Buyers can specify:
- Wire diameter and tensile grade.
- Barb length, spacing, and angle.
- Coating type and thickness.
- Roll length and core (inner diameter) for compatibility with dispensing equipment.
- Packaging: wooden pallets with protective film, or reusable steel reels.
Packaging and Shipping
Standard rolls are wrapped in UV‑stabilized polyethylene film, placed on pallets, and secured with steel straps. For long‑distance export, moisture‑absorbent desiccant packs are added inside the film to prevent corrosion during transit. Lead time is typically 2–4 weeks after receipt of technical drawings, depending on coating selection and order volume.
Frequently Asked Questions
Can the barb spacing be changed? Yes, spacing is adjusted during the twisting process and can be set between 75 mm and 150 mm to match design requirements.
What information is needed for a quotation? Required details include wire diameter, coating type, barb length, spacing, roll length, and any special packaging or testing requests.
Is PVC coating available in custom colors? Standard colors are green, black, and yellow; other RAL colors can be supplied upon request with possible minimum order quantities.
How is the tensile strength verified? Samples are tested according to ISO 6935‑2; results are included in the mill test report accompanying each shipment.
What is the typical lead time for a customized order? Usually 3–5 weeks, depending on coating complexity and order size.
