Factory Direct Razor Blade Barbed Wire
The core product consists of high‑tensile steel wire formed into a helical coil with razor‑sharp barbs pressed at regular intervals. Each barb is a precision‑stamped blade that provides a cutting edge on both sides, increasing deterrent effectiveness compared to conventional round‑wire barbs.
Material and Construction
Manufacturers select low‑alloy carbon steel with a typical carbon content of 0.6‑0.8 % and manganese up to 0.9 % to achieve a yield strength of approximately 550 MPa. The wire is cold‑drawn to a diameter of 2.5 mm before helically winding at a pitch of 45 mm, producing a nominal outer diameter of 30 mm for the coil.
Barbs are formed by pressing a 0.8 mm thick steel strip into a symmetrical V‑shape, then welding the strip to the coil at intervals of 100 mm. The welding process uses resistance spot welding, ensuring a tensile shear strength of at least 30 kN per barb.
- Wire diameter: 2.5 mm (±0.05 mm)
- Coil outer diameter: 30 mm (±1 mm)
- Barb length: 12 mm (±0.5 mm)
- Barb spacing: 100 mm (±5 mm)
- Tensile strength of wire: ≥550 MPa

Applications
Perimeter security for industrial facilities relies on a physical barrier that delays intrusion and causes measurable injury to deter climbing. The razor‑blade geometry creates a laceration risk that is difficult to mitigate with gloves, increasing the perceived cost of breach attempts compared to smooth or round‑barb alternatives.
Agricultural installations such as poultry farms and vineyards use the product to protect livestock and crops from wildlife. The stiff coil maintains tension over long spans, resisting sag caused by temperature fluctuations, while the sharp barbs deter animals without requiring frequent maintenance.
Correctional and military perimeters benefit from the high tensile strength and corrosion‑resistant options (galvanized or stainless steel), ensuring the barrier retains integrity under harsh environmental exposure and repeated impact attempts.
Quality Assurance
Each production lot undergoes dimensional verification using laser micrometers to confirm wire diameter, coil pitch, and barb spacing within specified tolerances. Mechanical testing includes tensile strength of the wire and shear strength of the barb welds, performed according to ISO 6892‑1 and ISO 9013 standards.
Surface treatment is inspected for coating thickness (zinc ≥ 55 µm for galvanized) using magnetic inductance gauges. Visual inspection under 10× magnification checks for welding defects such as cracks or incomplete fusion, ensuring every barb meets the required cutting edge geometry.

Packaging and Shipping
Finished coils are wound onto reusable steel spools with a core diameter of 150 mm, then wrapped in UV‑stabilized polyethylene film to prevent moisture ingress during transit. Spools are stacked on pallets with a maximum load of 2 tonnes, secured with polyester strapping and corner protectors.
For export shipments, each pallet receives a heat‑treated wooden crate compliant with ISPM‑15, reducing the risk of pest-related customs delays. Documentation includes material test reports, coating certificates, and a packing list detailing coil count, total weight, and dimensions.
Frequently Asked Questions
- Can the wire diameter be changed?
- Yes, diameters from 2.0 mm to 3.5 mm are available upon request, affecting tensile strength and coil stiffness.
- What information is needed for a quotation?
- Required details include desired wire material, coil diameter, barb length and spacing, total length, coating type, and delivery destination.
- How is quality inspected before shipment?
- Each lot undergoes dimensional checks, tensile and weld shear tests, and coating thickness measurement; results are documented in a test report supplied with the order.
- What packaging options exist for domestic versus international orders?
- Domestic orders use UV‑stabilized film on steel spools; international orders add ISPM‑15 compliant crates and additional corner protection.
- What is the typical lead time?
- Standard configurations ship within 10‑15 working days; customized material or dimensions may extend lead time to 20‑25 days.
