Anping Xinye Metal Wire Mesh Products Co., Ltd, based in the wire mesh industrial hub of Hengshui, Hebei, China, brings you a premium Hot-Dipped Galvanized Metal Barbed Wire that sets the standard for durability and performance. With a wire diameter of 2.5mm, 4-inch barb spacing, and a convenient 50kg per coil, this product is manufactured in strict compliance with ASTM A121 specifications. Whether you are securing a farm, protecting a construction site, or demarcating a border, this barbed wire offers a reliable, long-lasting solution that resists corrosion and withstands harsh environmental conditions. Our experience in wire mesh manufacturing ensures that every coil meets rigorous quality checks, giving you confidence in your purchase.
This product is designed for customers who demand strength and longevity. The hot-dipped galvanized coating provides a thick, uniform layer of zinc that protects the steel core from rust, even in humid or coastal environments. The 2.5mm wire diameter delivers excellent tensile strength, while the 4-inch barb spacing ensures effective deterrence without excessive material usage. Each coil weighs 50kg, making it easy to handle and transport while providing enough material for medium to large fencing projects. Trust Anping Xinye to deliver consistent quality for your security and agricultural needs.
Key Features & Benefits
- Hot-Dipped Galvanized Coating: Superior corrosion resistance compared to electro-galvanized alternatives. The zinc layer adheres firmly, preventing peeling and extending service life by 3–5 times in outdoor applications.
- 2.5mm Wire Diameter: Offers a balanced combination of flexibility and strength. Suitable for stretching between posts without breaking, while maintaining a rigid barrier.
- 4-Inch Barb Spacing (Approx. 100mm): Optimized for effective animal control and security. The distance between barbs is standardized to prevent easy passage while minimizing material costs.
- 50kg per Coil: Convenient weight for manual handling and machine installation. Each coil contains approximately 250–300 meters of barbed wire (depending on barb spacing and wire gauge).
- ASTM A121 Compliance: Manufactured under strict quality control to meet the American Society for Testing and Materials standard for barbed wire. This ensures consistent tensile strength, zinc coating weight, and barb dimensions.
- Versatile Application: Ideal for agricultural fencing (cattle, sheep, horses), perimeter security for industrial sites, military installations, prisons, and residential boundary marking.
- Easy Installation: The wire is wound in a uniform coil, allowing smooth unwinding and tensioning. Compatible with standard barbed wire tensioners, staples, and posts.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between hot-dipped galvanized and electro-galvanized barbed wire?
A: Hot-dipped galvanized (HDG) barbed wire is coated by immersing the wire in molten zinc, resulting in a thicker, more durable coating that resists rust for 15–20 years in moderate environments. Electro-galvanized wire has a thinner coating and is more prone to corrosion, especially in wet or coastal areas. Our product is HDG for maximum longevity. -
Q: Is this barbed wire suitable for use with electric fencing?
A: This barbed wire is not specifically designed for electric fencing. However, it can be used as a physical barrier alongside electric wires. If you need an electrified system, we recommend using smooth galvanized wire or a combination. Please contact us for tailored solutions. -
Q: How many meters of barbed wire are in a 50kg coil?
A: The length varies slightly based on exact wire diameter and barb spacing. For a 2.5mm core wire and 4-inch barb spacing, you can expect approximately 280–320 meters per coil. The exact length is calculated before shipment and can be provided upon request. -
Q: Can I get a custom barb spacing or wire diameter?
A: Yes, we offer customization options. Common barb spacings include 3 inches, 5 inches, and 6 inches, and wire diameters from 1.8mm to 3.0mm. Minimum order quantities may apply for non-standard specifications. Contact our sales team for details. -
Q: Does the barbed wire meet ASTM A121 standard? How can I verify?
A: Yes, our product is manufactured to comply with ASTM A121 – Standard Specification for Barbed Wire. We provide a mill test certificate (MTC) or third-party inspection report upon request. The zinc coating, tensile strength, and barb dimensions are tested accordingly. -
Q: What is the recommended post spacing for this barbed wire?
A: For a 2.5mm wire, typical post spacing is 10–15 feet (3–4.5 meters) for a tight fence. If you use line posts and end posts, the spacing can be adjusted. We recommend using a tensioning tool to achieve proper sag reduction. -
Q: Is the barbed wire supplied in single twist or double twist?
A: Our standard barbed wire is double twist (two strands twisted together) for added strength. Single twist (one strand) is also available upon request. Double twist provides better rigidity and resistance to unwinding. -
Q: Do you offer small quantities for trial orders?
A: Yes, we accept trial orders of 1–5 coils for new customers. Sample coils are available at a nominal cost, which can be deducted from your first bulk order. Contact us to arrange a sample.
