Concertina Razor Wire Coils specification
Concertina razor wire coils are a type of security barrier commonly used for high-level protection. They are characterized by sharp razor-like edges designed to deter or prevent unauthorized access. Here are the common specifications for Concertina Razor Wire Coils:
1. Material:
Blade Material: Galvanized steel or stainless steel (typically AISI 304, AISI 316).
Core Wire: Galvanized high tensile steel wire (2.5 mm to 2.8 mm in diameter).
2. Blade Type:
Blades are typically made in a variety of profiles such as BTO (Barbed Tape Obstacle) or CBT (Concertina Barbed Tape).
BTO-10, BTO-22, CBT-60, and CBT-65 are common models:
BTO-10 and BTO-22 are more common for medium security.
CBT-60 and CBT-65 are for high-security needs (larger and sharper blades).
3. Blade Specifications:
Blade Thickness: 0.5 mm ± 0.05 mm.
Blade Length: 10 mm to 65 mm (depending on model).
Blade Width: 15 mm to 21 mm.
Blade Spacing: 26 mm to 100 mm, based on design.
4. Coil Diameter:
Small Coils: 300 mm to 500 mm.
Medium Coils: 600 mm to 900 mm.
Large Coils: 1000 mm to 1200 mm.
Coil diameter influences the area it can cover and how easily it can be stretched into a barrier.
5. Length:
Unstretched Length: Typically ranges between 8 to 15 meters.
Stretched Length: Coils can extend to 10–20 meters depending on the type of coil and the tension applied.
6. Tensile Strength:
The steel core wire typically has a tensile strength of 1240–1500 MPa to resist cutting or breaking.
7. Number of Loops:
Concertina coils have 33, 56, or 60 loops depending on the diameter and type of application.
8. Coil Weight:
Varies depending on the size, but generally ranges between 5 kg to 20 kg per roll for manual handling and ease of installation.
9. Surface Treatment:
Galvanized: To prevent rust and corrosion in outdoor conditions.
Stainless Steel: For superior rust resistance in harsh environments.
10. Usage:
Perimeter Fencing: Around military, prison, and industrial sites.
Barrier Extensions: Mounted on walls, fences, or standalone as temporary security measures.
11. Connection Types:
Clip Connected: Often, coils are connected by metal clips at intervals to hold their shape when expanded.
Looped: Ends can be looped together for further connection and continuous deployment over large areas.
