Processing:

The four-point barbs of mild steel wire fit onto the line wire, spaced at 60 ± 15mm intervals. The barbed wire twists tightly around the line wire with about four turns. The sharp bevel points form at right angles to each other and project 15-20mm from the wire’s centerline.

Coil Formation:

Position the barbs at an oblique angle of at least 45° to the line wire. Fix the barbs securely to prevent movement under 50 Newton axial force or 0.1 Newton meter torque.

After barbing, coil the wire into 68 ± 1 turns, creating 1-meter diameter coils. Clip adjacent coils at 72° intervals, forming a five-row diamond pattern when extended to 15 meters (±0.5m).

Single Twisted vs. Double Strand Barbed Wire:

The choice between single and double strand barbed wire depends on security needs, budget, and installation preferences:

Single Strand Barbed Wire: Ideal for low-security fencing, easy to install, and cost-effective.
Double Strand Barbed Wire: Offers enhanced security and strength, making it suitable for high-risk applications.

This high-tensile barbed wire ensures durability and reliability, making it an excellent choice for fencing in grassland and other security-sensitive areas.
