Factory Direct Razor Wire Security Fencing

Razor wire fencing consists of high‑tensile steel core wrapped with sharply profiled barbs that are cold‑formed to a consistent helical geometry. The core diameter typically ranges from 2.5 mm to 3.2 mm, providing tensile strength above 1500 MPa, while the barb profile creates a cutting edge with an average tip radius of 0.3 mm to deter climbing or cutting attempts.

Core Design Specifications

The helical pitch is maintained at 45 mm ± 2 mm, ensuring uniform barrier density when installed in standard post spacings of 3 m. Each linear meter contains approximately 22 barbs, which translates to a barrier coverage of roughly 0.018 m² per meter of fencing. The finished coil weight averages 12 kg per 50 m roll, allowing manual handling with standard lifting equipment.

Corrosion protection is applied via a hot‑dip galvanized coating of 55 µm minimum thickness, meeting ISO 1461 standards. For environments with high chloride exposure, an optional PVC over‑coat adds 0.4 mm thickness, increasing service life to beyond 15 years in marine atmospheres.

Material Options

• Cold‑drawn high‑carbon steel wire (grade 1080) – standard tensile strength 1550 MPa
• Stainless steel grade 304 core – tensile strength 520 MPa, inherent corrosion resistance
• Galvanized steel core with zinc‑aluminum alloy coating – coating weight 260 g/m²
• PVC‑coated galvanized core – PVC thickness 0.4 mm, UV‑stabilized

Typical Applications

Perimeter security for critical infrastructure such as substations, water treatment plants, and telecommunications towers relies on the wire’s ability to impede unauthorized access without requiring continuous power.

Correctional facilities utilize razor wire atop existing chain‑link or welded mesh fences to increase climb resistance, reducing the need for additional patrol resources.

Industrial storage yards and logistics centers deploy the fencing as a low‑maintenance deterrent against cargo theft, especially where ground‑level surveillance is limited.

Quality Assurance Process

Each production lot undergoes dimensional verification using laser micrometers, confirming core diameter tolerance within ± 0.05 mm and barb height uniformity within ± 0.2 mm.

Tensile testing follows ASTM A370, with specimens extracted from the core and barb zones; acceptance criteria require minimum yield strength of 1300 MPa for carbon steel variants.

Coating thickness is measured via magnetic induction probe on a minimum of five random points per roll; average zinc mass must exceed 260 g/m² for hot‑dip galvanized products.

Customization Capabilities

Barb geometry can be adjusted from the standard 45° angle to 30° or 60° to suit specific threat assessments, altering the cutting efficiency while maintaining core integrity.

Coil lengths are configurable from 20 m to 100 m, with corresponding inner core diameters scaled to maintain consistent tensile load per meter.

End finishes include loops, hooks, or welded terminals to facilitate rapid attachment to existing posts or concrete barriers without additional hardware.

Frequently Asked Questions

Can dimensions be customized?

Yes, core diameter, barb angle, and coil length are adjustable based on project specifications; provide the required tensile load and exposure conditions for a tailored quote.

What information is needed before quotation?

We require the intended installation height, post spacing, environmental corrosivity class (per ISO 9223), and any preferred finish (galvanized, PVC, stainless).

How is quality inspected?

Every roll undergoes dimensional laser checks, tensile sampling, and coating thickness measurement; results are documented in a test certificate accompanying each shipment.

What packaging methods are available?

Standard packaging uses UV‑stabilized polyethylene wrap with corner protectors; wooden pallets or steel frames are available for bulk orders upon request.

What is the typical production lead time?

Lead time ranges from 2 weeks for standard galvanized rolls to 4 weeks for PVC‑coated or stainless variants, depending on order volume and current capacity.
