Galvanized steel barbed wire fence consists of high‑carbon steel wire coated with a uniform zinc layer to resist corrosion, formed into strands with regularly spaced barbs that deter intrusion. This product is supplied directly from the manufacturer’s facility, eliminating intermediary handling and reducing lead times for international buyers.
Material Composition and Galvanization
The core wire is typically made from low‑alloy carbon steel with a carbon content between 0.6% and 0.9%, providing a tensile strength range of 450 MPa to 550 MPa after cold drawing. A hot‑dip galvanizing process applies a zinc coating weight of 100 g/m² to 275 g/m², measured according to ASTM A123, which protects the steel against rust in humid or saline environments.
Design Specifications
Buyers can select wire diameter, barb spacing, and barb length to match security requirements and installation constraints. The following table shows typical values that can be adjusted per project.
| Parameter | Typical Range | Unit |
|---|---|---|
| Wire diameter | 2.0 – 3.0 | mm |
| Barb spacing | 75 – 150 | mm |
| Barb length | 15 – 20 | mm |
| Tensile strength | 450 – 550 | MPa |
| Zinc coating weight | 100 – 275 | g/m² |
Manufacturing Process
Wire is first drawn through a series of dies to achieve the target diameter, increasing its tensile strength via work hardening. The drawn wire is then cleaned, fluxed, and immersed in a molten zinc bath at approximately 450 °C, forming a metallurgical bond that yields a uniform coating. After galvanizing, the wire is twisted into two‑strand or four‑strand configurations, and barbs are formed by cutting and twisting short lengths of wire at programmed intervals.
Quality Control and Testing
Each production lot undergoes dimensional inspection using calibrated micrometers, coating thickness measurement with magnetic gauges, and tensile testing on a universal testing machine. Visual inspection checks for uniform barb formation and absence of zinc defects such as bare spots or drips. Test results are recorded and traceable to the specific coil number.
Applications in Industrial Settings
- Perimeter security for warehouses and logistics centers, where the fence deters climbing and provides a clear visual barrier that integrates with CCTV monitoring.
- Protection of outdoor storage yards for bulk materials such as aggregates or timber, where corrosion resistance extends service life in exposed environments.
- Boundary delineation for manufacturing plants, facilitating controlled access zones while allowing rapid installation on uneven terrain.
Packaging and Export Logistics
Finished coils are wrapped in water‑resistant polyethylene film, placed on steel‑banded pallets, and secured with corner protectors to prevent deformation during transit. Standard container loading accommodates up to 20 tons per 40‑foot container, and each pallet is labeled with product code, coil weight, and destination details for customs clearance.
