Wholesale ODM Razor Barbed Wire Supplier
Razor barbed wire combines a high-tensile steel core with sharp, angular barbs that deter climbing and cutting attempts. The product is manufactured to order (ODM) for wholesale distributors who require consistent dimensions, tensile strength, and corrosion resistance across large roll lengths.
Product Overview
The core wire is typically cold-drawn steel with a diameter ranging from 2.0 mm to 3.5 mm, depending on the required breaking load. Barbs are formed by pressing or welding triangular protrusions at regular intervals, usually every 50 mm to 150 mm along the wire.
Material Composition and Mechanical Properties
Engineers select the base steel based on the target tensile strength and environmental exposure. The following table summarizes typical values and relevant test standards for the most common configurations.
| Property | Typical Value | Test Standard |
|---|---|---|
| Core wire diameter | 2.0 mm – 3.5 mm | ASTM A228 |
| Tensile strength | 1 200 MPa – 1 800 MPa | ASTM A370 |
| Yield strength (0.2% offset) | 900 MPa – 1 500 MPa | ASTM A370 |
| Elongation at break | 8 % – 12 % | ASTM A370 |
| Zinc coating (hot‑dip galvanized) | 60 g/m² – 120 g/m² | ASTM A123 |
| PVC coating thickness (if applied) | 0.3 mm – 0.5 mm | ISO 1461 |
Zinc coating provides sacrificial protection in humid environments, while a PVC overcoat adds UV resistance and reduces handling injuries. The selected coating weight directly influences expected service life in outdoor installations.
Design Variations
Several barb geometries are offered to suit different threat levels and installation constraints.
- Concertina coil – helical winding provides self‑supporting barrier; typical coil diameter 450 mm–600 mm.
- Flat‑strip razor – barbs pressed onto a flat steel strip; used for wall tops and fence panels.
- Helical razor – barbs wound around a central core wire; offers high flexibility for uneven terrain.
Typical Applications and Industrial Benefits
Perimeter security remains the primary driver for razor barbed wire specification in critical infrastructure.
- Electrical substations – prevents unauthorized climbing while maintaining clear visibility for inspections.
- Warehouse and logistics yards – deters theft and vandalism with minimal maintenance.
- Correctional facilities – provides a high‑deterrent barrier that integrates with existing fence systems.
- Border and military installations – offers rapid deployment and reliable performance under harsh weather.
The high tensile strength limits sag over long spans, reducing the need for intermediate tensioning points. Sharp barbs increase the time and effort required for intrusion attempts, thereby lowering the likelihood of successful breach.
Customization Options (ODM)
ODM production enables precise tailoring of wire geometry to project constraints such as load requirements, corrosion exposure, and installation hardware.
| Option | Range | Remarks |
|---|---|---|
| Core wire diameter | 1.8 mm – 4.0 mm | Affects tensile strength and weight per meter. |
| Barb height | 10 mm – 25 mm | Higher barbs increase deterrence but may raise handling risk. |
| Barb pitch | 30 mm – 200 mm | Closer pitch yields more barriers per meter. |
| Coating type | Hot‑dip Zn, Zn‑Al, PVC, polyester | Selected based on corrosivity class (C1–C5 per ISO 12944). |
| Roll length | 50 m – 500 m | Custom lengths reduce splice points in long runs. |
Quality Assurance and Testing
Quality control begins with incoming wire inspection and continues through each production stage.
- Diameter and tensile strength verified per lot using calibrated micrometers and tensile testers.
- Barb geometry inspected optically to ensure conformance to specified height and angle.
- Coating thickness measured with magnetic or eddy‑current probes; adhesion assessed via cross‑cut test.
- Salt spray (fog) exposure conducted per ASTM B117 to predict corrosion life.
- Final product undergoes visual inspection for defects such as nicks, uneven winding, or coating holidays.
Packaging and Logistics
Finished rolls are protected to prevent damage during transit and storage.
- Each roll is wrapped in UV‑stabilized polyethylene film to keep moisture and contaminants away.
- Rolls are placed on wooden or plastic pallets, secured with polyester strapping, and labeled with product code, length, and weight.
- Standard pallet dimensions accommodate 20‑foot and 40‑foot container loading, optimizing freight costs.
- For export, pallets are fumigated and fitted with corner protectors to meet ISPM‑15 requirements.
FAQ
Can dimensions be customized?
Yes. Core diameter, barb height, pitch, and coating type are all adjustable according to project specifications. Provide the required tensile strength and environmental class for a precise quote.
What information is required before quotation?
We need the intended application, approximate perimeter length, desired coating (e.g., hot‑dip galvanized, PVC), and any regulatory standards (e.g., ISO 12944, ASTM). Drawings or sketches help optimize roll length and packaging.
How is quality inspected?
Each lot undergoes dimensional checks, tensile testing, coating thickness measurement, and salt spray exposure. Test reports are available upon request.
What packaging methods are available?
Standard packaging includes UV‑stabilized film wrap, palletizing, and strapping. Custom options such as corrosion‑inhibiting VCI bags or reusable crates are offered for special projects.
