The CBT 65 razor wire is a high‑tensile steel barrier formed by wrapping sharp‑angled barbs around a core wire, creating a continuous helical coil. Its nominal core diameter is 2.5 mm and the overall outer diameter after forming is approximately 6.5 mm, giving the product its designation. These dimensions provide a balance between tensile strength and flexibility for perimeter security applications.
Key Technical Specifications
- Core wire tensile strength: ≥ 1 800 MPa (typical for cold‑drawn high‑carbon steel)
- Barb angle: 45° ± 3°, providing consistent penetration resistance
- Coil pitch: 12 mm ± 1 mm, determining coverage per linear meter
- Weight per meter: approx. 0.42 kg/m (± 5 %)
- Corrosion protection: hot‑dip galvanized coating ≥ 270 g/m² (Zn) or optional PVC‑coated finish
Typical Applications
In high‑security perimeters such as military bases, correctional facilities, and critical infrastructure sites, the CBT 65’s helical geometry creates a continuous obstacle that is difficult to cut or climb without specialized tools. The 6.5 mm outer diameter offers sufficient rigidity to resist deformation under impact, while the galvanized coating maintains barrier integrity in humid or coastal environments for extended service life.
Material and Finish Options
- Base wire: cold‑drawn high‑carbon steel (ASTM A228 equivalent)
- Standard finish: hot‑dip galvanized per ISO 1461
- Optional finish: PVC‑coated (black or green) for added UV resistance and aesthetic blending
- Custom alloy: stainless‑steel grade 304 or 316 available upon request for corrosive chemical environments
Customization Capabilities
Manufacturers can adjust the core wire diameter (from 2.0 mm to 3.0 mm) to modify tensile strength and weight, alter the barb length (typically 15 mm to 25 mm) to change penetration depth, and vary the coil pitch to achieve specific coverage rates. Lengths are supplied in standard coils of 50 m or 100 m, but custom spool sizes can be arranged to match installation logistics.
Quality Control and Testing
Each production batch undergoes dimensional verification using laser micrometers (± 0.02 mm accuracy), tensile testing of core wire samples to confirm strength thresholds, and coating thickness measurement via magnetic induction. Visual inspection ensures barb uniformity and absence of defects such as cracks or incomplete galvanization before packaging.
Packaging and Handling
Coils are wrapped in water‑resistant polyethylene film, placed on wooden pallets, and secured with steel strapping to prevent deformation during transit. For export shipments, additional corner protection and moisture‑absorbent desiccant packs are included to maintain coating integrity.
