Razor barbed wire consists of a hardened steel core wrapped with uniformly spaced, razor‑sharp barbs. The geometry of each barb is engineered to maximize snag resistance while minimizing material usage. This configuration provides an effective physical barrier for security perimeters, agricultural enclosures, and construction site protection.

Material and Construction

The core wire is typically cold‑drawn high‑carbon steel with a diameter ranging from 2.0 mm to 2.8 mm, selected for its yield strength above 450 MPa. Barbs are formed from the same wire stock, pressed into a 45° angle and trimmed to a length of 12 mm to 18 mm. A zinc‑aluminum coating (Zn‑5%Al) is applied to improve corrosion resistance in outdoor environments.

Technical Specifications

Applications

• Perimeter security for warehouses, factories, and storage yards where a visible deterrent reduces unauthorized entry.
• Livestock containment on farms; the sharp barbs discourage animals from pushing against fences while the flexible core accommodates ground movement.
• Temporary site fencing for construction projects; lightweight rolls allow rapid deployment and retrieval.
• Highway median barriers in regions where cost‑effective impact resistance is required.

Quality Control Process

Each production batch undergoes dimensional verification using laser micrometers to confirm core diameter and barb spacing within ±0.1 mm. Tensile testing is performed on random samples per ISO 6892‑1 to validate strength consistency. Coating thickness is measured with magnetic induction gauges targeting 55 µm ± 10 µm for zinc‑aluminum layers. Visual inspection under 10× magnification ensures barb tips are free of burrs that could prematurely fail under tension.

Customization Options

Clients may specify alternative core alloys such as stainless‑steel grade 304 for environments with high chloride exposure. Barb geometry can be adjusted to a reverse‑angle configuration for increased snag resistance on uneven terrain. Roll lengths are available from 25 m to 500 m, and inner core diameters can be fitted with PVC sleeves for added handling safety.

Packaging and Shipping

Standard packaging places each roll in a polyethylene sleeve, then stacks rolls on a wooden pallet secured with stretch film. For export, pallets are fitted with corner protectors and wrapped in a weather‑resistant tarp. Custom packaging options include cardboard boxes with foam inserts for smaller quantities or reusable steel cages for repeated shipments.

Lead Time and Sampling

Typical production lead time is 18‑22 working days after receipt of confirmed specifications and deposit. Sample lengths of 5 m can be prepared within 5 working days, with shipping costs borne by the requester. Sample evaluation includes tensile measurement, coating adhesion test, and barb sharpness verification.

Frequently Asked Questions

• Can the barb spacing be altered without changing the core diameter? Yes, spacing is independent of core gauge and can be adjusted via the forming die.
• What information is required before a quotation? Required details include desired core diameter, barb length, spacing, coating type, roll length, and delivery destination.
• How is coating adhesion verified? Adhesion is tested using the ASTM D4541 pull‑off method on coated samples.
• Are there minimum order quantities? Minimum order is typically 500 kg of wire, negotiable for trial orders.
• How are shipments protected against corrosion during transit? Pallets are wrapped in vapor‑corrosion inhibitor (VCI) film and kept dry within sealed containers.
