Razor wire consists of a high‑tensile steel core wrapped with sharp barbs spaced at regular intervals. The assembly creates a continuous barrier that resists climbing and cutting attempts, making it suitable for residential perimeter protection when installed correctly.
Material and Construction
The core wire is typically cold‑drawn steel with a diameter ranging from 2.5 mm to 3.5 mm, providing a tensile strength of at least 1 800 MPa. Barbs are formed from the same wire stock, pressed into a helical shape with a length of 22 mm and a base width of 8 mm to maximize snag resistance.
Corrosion protection is achieved through hot‑dip galvanizing (minimum 60 g/m² zinc) or, for higher‑exposure environments, a duplex system of galvanizing followed by a polymer coating. Stainless‑steel grades (304 or 316) are available when chloride exposure or aesthetic requirements demand it.
Technical Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Core wire diameter | 2.5 mm – 3.5 mm | Selected per load requirement |
| Barb length | 22 mm | Helical pitch 12 mm |
| Barb spacing | 100 mm – 150 mm | Adjustable for custom coils |
| Tensile strength | ≥1 800 MPa | Measured per ASTM A370 |
| Coating weight (galvanized) | ≥60 g/m² | Equivalent to ~8 µm zinc |
| Operating temperature | -40 °C to +80 °C | No loss of tensile properties |
Customization Options
Coil diameter can be varied from 150 mm to 500 mm to suit different fence heights and installation methods. Barb spacing is adjustable in 10 mm increments, allowing designers to balance deterrence with visual impact. End treatments include crimped loops, welded eyes, or plastic caps for safe handling.
Coating choices extend beyond standard galvanizing to include powder‑coated colors (RAL 9005 black, RAL 7016 gray) for architectural integration, or a PVC over‑coat for added abrasion resistance. Lengths are supplied in continuous rolls or pre‑cut sections with tolerances of ±2 %.
Residential Security Applications
When mounted on the top of a perimeter fence, razor wire creates a continuous overhang that prevents intruders from gaining a foothold. The helical barb geometry distributes force across multiple points, reducing the likelihood of a single‑point cut compared with straight barbed tape.
Installation on masonry walls or wooden posts requires compatible brackets that maintain a minimum clearance of 50 mm between the wire and the structure, ensuring the barbs remain effective without damaging the substrate. Proper tensioning (typically 200 N–300 N per meter) preserves the helical shape and prevents sagging over time.
Quality Assurance and Testing
Each production lot undergoes visual inspection for barb uniformity and coating continuity, followed by tensile testing on a sample length of 1 m to confirm strength specifications. Adhesion of galvanized or polymer coatings is evaluated via bend‑test per ISO 2409, ensuring no flaking under impact.
Corrosion resistance is validated through salt‑spray exposure (ASTM B117) for 500 hours, with acceptance criteria of less than 5 % red rust on the surface. Dimensional checks confirm barb spacing and coil diameter within the tolerances stated in the specification sheet.
Frequently Asked Questions
- Can dimensions be customized? Yes, wire diameter, barb spacing, coil diameter, and length are all adjustable to match project requirements.
- What information is needed for a quotation? Provide fence height, post spacing, desired coating type, and any special end‑treatment or color requirements.
- Which materials are available? Core options include cold‑drawn steel, galvanized steel, duplex‑coated steel, and stainless‑steel grades 304 or 316.
- How is quality inspected? Visual checks, tensile testing, coating adhesion, and salt‑spray tests are standard for each batch.
- What packaging methods are offered? Rolls are wrapped in UV‑stabilized polyethylene film and placed on pallets with corner protection; cut lengths are packed in sturdy cartons with internal separators.
- How are export shipments protected? Desiccant packets and vapor‑corrosion inhibitors are included inside the packaging to prevent moisture damage during transit.
- What is the typical lead time? Production typically requires 2–3 weeks after drawing approval, depending on order volume and coating complexity.
- Are samples available? Sample sections up to 1 meter can be dispatched upon request, with the customer covering shipping costs.
