Product Overview
Razor barbed wire combines a high‑tensile steel core with sharply formed barbs that are helically wound around the strand. The design provides a dual‑function barrier: the core resists tensile loads while the barbs create a painful deterrent that discourages climbing or cutting attempts.
Material and Construction
The core wire is typically made from low‑carbon steel (SAE 1006‑1010) with a tensile strength of 350–450 MPa, galvanized to a minimum coating weight of 275 g/m² (Zn) for corrosion resistance. The barbs are formed from the same galvanized wire, cut to a length of 15–20 mm and twisted at a pitch of 100–120 mm along the core.
Optional stainless‑steel (AISI 304) cores are available for environments with high chloride exposure, offering a tensile strength of 520 MPa and a passive oxide layer that resists rust without additional coating.
Technical Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Core Diameter | 2.5 mm | Customizable 2.0–3.0 mm |
| Barb Length | 18 mm | Adjustable 12–25 mm |
| Pitch (Barb Spacing) | 110 mm | Standard; can be 80–150 mm |
| Tensile Strength (Core) | 380 MPa (galvanized) | Stainless steel up to 520 MPa |
| Coating Weight (Zn) | 275 g/m² | Hot‑dip galvanized |
Applications
- Perimeter security for industrial facilities, warehouses, and logistics centers where a physical deterrent reduces unauthorized entry.
- Correctional and detention centers, where the combination of tensile resistance and painful barbs delays escape attempts.
- Agricultural fencing to protect livestock from predators while maintaining low maintenance due to galvanized coating.
- Infrastructure projects such as highway medians and bridge approaches, where the wire withstands wind loads and provides a visible barrier.
Quality Control and Testing
Each batch undergoes dimensional verification using laser micrometers (±0.02 mm tolerance) and tensile testing according to ASTM A370. The zinc coating thickness is measured by magnetic‑induction gauges to confirm compliance with ISO 1461. Visual inspection ensures barb uniformity and absence of surface defects that could compromise performance.
Customization Options
Buyers can specify core diameter, barb length, pitch, and coating type (hot‑dip galvanized, Galfan, or stainless steel). Lengths are supplied in standard rolls of 50 m or 100 m, with spliceless joints available upon request for continuous installations.
Packaging and Shipping
Rolls are wrapped in UV‑stabilized polyethylene film, placed on wooden pallets, and secured with steel strapping. Export containers receive corner protectors and moisture‑absorbent desiccant packs to prevent corrosion during transit.
Frequently Asked Questions
Can dimensions be customized?
Yes. Core diameter, barb length, and pitch are adjusted according to project requirements; tooling changes are minimal for diameters between 2.0 mm and 3.5 mm.
What information is needed for a quotation?
Required details include desired length, core material (galvanized steel or stainless steel), coating weight, barb specifications, and delivery destination.
How is quality inspected before shipment?
Every roll is sampled for tensile strength, coating weight, and dimensional accuracy; a test certificate accompanies each shipment.
