Factory Direct Galvanized Concertina Razor Wire
Concertina razor wire is formed from cold‑drawn high‑carbon steel wire (typically 0.8 mm to 1.2 mm diameter) that is helically wound around a central core and fitted with uniformly spaced barbs. The galvanized coating is applied by hot‑dip zinc plating, providing a minimum zinc mass of 275 g/m² (ISO 1461).
Core Mechanical Properties
The steel core delivers a tensile strength of 1 500 MPa ± 100 MPa and a yield strength of 1 200 MPa ± 80 MPa. These values enable the wire to resist cutting attempts while maintaining flexibility for coiling and deployment.
Typical Dimensions
| Parameter | Typical Value | Unit |
|---|---|---|
| Core wire diameter | 0.9 – 1.1 | mm |
| Barb length | 12 – 18 | mm |
| Coil outer diameter | 450 – 600 | mm |
| Pitch (distance between loops) | 30 – 50 | mm |
| Zinc coating mass | ≥275 | g/m² |
Manufacturing Process Overview
The process begins with drawing high‑carbon steel wire to the target diameter, followed by cleaning and pickling to remove oxides. The wire is then helically wound around a mandrel while barbs are formed by pressing or cutting. After winding, the coil passes through a hot‑dip galvanizing bath at approximately 450 °C, then is cooled and inspected for coating uniformity.
Applications and Suitability
- Perimeter security for industrial facilities, where the helical shape allows rapid installation over uneven terrain.
- Correctional and detention centers, providing a high‑climb deterrent due to the sharp barbs and tensile resistance.
- Military forward operating bases, where galvanized coating ensures longevity in harsh climates.
- Infrastructure protection (substations, water treatment plants) where low maintenance life‑cycle cost is required.
Quality Control & Testing
Each batch undergoes dimensional verification with calibrated calipers, tensile testing of wire samples per ASTM A370, and coating thickness measurement using magnetic induction (ISO 1461). Visual inspection checks for barb uniformity and coil integrity before packaging.
Customization Options
Clients may specify alternative core diameters (0.6 mm to 1.5 mm), barb spacing, coil height, or zinc coating class (e.g., Z275, Z350) according to project requirements. Lengths are supplied in standard rolls of 10 m to 50 m or cut to length on request.
Packaging and Logistics
Coils are wrapped in UV‑stabilized polyethylene film, placed on wooden pallets, and secured with steel straps. For export, pallets are fumigated and fitted with corner protectors to prevent deformation during transit.
Frequently Asked Questions
