Razor wire, also known as barbed tape or concertina wire, is a high-security fencing material featuring sharp, blade-like edges. Unlike traditional barbed wire, it is designed for maximum deterrence and is widely used in military, prison, and critical infrastructure protection. Below are its key specifications and applications:

1. Key Specifications

Material

Galvanized Steel: Most common; zinc-coated for rust resistance.

Stainless Steel: Premium corrosion resistance for coastal or industrial environments.

PVC-Coated Steel: Adds weatherproofing and color options (e.g., green, black).

Blade Types

Standard Razor Blades:

BTO-10/22: Single-edge blades (10 mm height, 22 mm length).

BTO-12/30: Double-edge blades (12 mm height, 30 mm length).

Concertina Coils: Pre-formed helical coils for rapid deployment.

Flat Wrap Razor Tape: Flat blades for wall-mounted or layered fencing.

Wire Gauge

Core Wire: Typically 2.5 mm to 3.0 mm (12–11 gauge).

Blade Thickness: 0.5–0.7 mm for durability.

Coil Dimensions

Diameter: 450–1,000 mm (18–40 inches).

Length: 7–15 meters (23–50 feet) per coil.

Layers: Single, double, or triple coils for enhanced barriers.

Tensile Strength

Core wire: 1,200–1,500 MPa (high-tensile steel).

Coating

Hot-Dip Galvanized: Class 3 (≥245 g/m² zinc) for harsh environments.

PVC Coated: 0.3–0.5 mm thickness for UV and abrasion resistance.

2. Common Applications

Military & Border Security

Perimeter fencing for military bases, borders, and conflict zones.

Concertina coils stacked in layers (triple-coil systems).

Prisons & Detention Centers

Installed atop walls or fences to prevent escapes.

Uses stainless steel or PVC-coated razor wire for longevity.

Critical Infrastructure

Power plants, airports, and data centers.

Flat-wrap razor tape for wall-mounted security.

Commercial & Residential Security

High-risk properties, warehouses, and private estates.

Galvanized razor wire combined with electric fencing.

Temporary Barriers

Rapid deployment for crowd control or disaster zones.

Pre-formed concertina coils on portable frames.

3. Installation Methods

Concertina Coils:

Stacked horizontally or vertically using brackets or clamps.

Often paired with chain-link or welded mesh fences.

Wall-Mounted:

Flat-wrap razor tape fixed to walls, gates, or rooftops.

Freestanding Barriers:

Coils mounted on concrete barriers or steel frames.

4. Standards & Certifications

ASTM A121: Specifies galvanized razor wire quality.

ISO 1461: International standards for hot-dip galvanizing.

NATO STANAG: Military-grade specifications for conflict zones.

5. Environmental Considerations

Coastal Areas: Stainless steel or Class 3 galvanized wire.

High Rainfall: PVC coating prevents rust and blade corrosion.

UV Exposure: UV-resistant coatings extend lifespan.

6. Safety & Maintenance

Handling: Use heavy-duty gloves and protective gear.

Inspections: Check for blade damage, rust, or sagging annually.

Replacement: Blunt or corroded blades reduce effectiveness.
