Making cold drawn steel wires
Cold Drawn Steel Wire is the essential starting point in the fabrication of high-performance wire mesh fencing. Manufactured by pulling hot rolled steel wire rods through precision dies at room temperature, this process significantly enhances the wire’s tensile strength, dimensional accuracy, and surface finish.
Steel wire standards used in (3D Welded Wire Fence)
| Region | Main Mesh Standard | Coating Standard | Galvanizing Standard |
|---|---|---|---|
| ASTM of the United States | ASTM F2453 / A1064 | ASTM A641 | ASTM A123 |
| Europe EN | EN 10223-7 | EN 10244-2 | EN ISO 1461 |
| BS (UK) | BS EN 10223-7 / BS 1722-14 | BS EN 10244-2 | BS EN ISO 1461 |
| AU/NZ | EN 10223-7 (adapted) | AS 2423 / AS/NZS 4534 | AS/NZS 4680 |
Welding steel wires
After producing high-strength Cold Drawn Steel Wire, the next critical stage in wire mesh fence manufacturing is Welding Wire Mesh. This step involves accurately positioning longitudinal and transverse wires, then fusing them at their intersections using automated resistance welding machines. The result is a rigid, uniform mesh grid with consistent spacing and excellent strength.
Welding steel wires specifications
| Item | Specification |
|---|---|
| Welding Method | Resistance spot welding (Automatic) |
| Resistance spot welding (Automatic) | ≥1000 N (No weld breakage) |
| Bending (Reinforcement) | V-shaped folds, 2–4 bends |
Making fence post
The third step in wire mesh fence production is Forming the Fence Post, specifically shaping steel banding into a Peach-Shaped Fence Post. This process begins with high-quality galvanized or cold rolled steel strips, which are precision folded and pressed through custom-designed molds to create the signature “peach” profile — named for its rounded, ribbed sides and flat back.
| Item | Specification / Description |
|---|---|
| Material | Q195 / Q235 / |
| Forming Method | Cold roll forming |
| Applicable Standards | GB/T 3091 / EN 10219 / ASTM A500 / AS/NZS 1163 |
Galvanizing
Once the wire mesh panels are welded and the peach-shaped fence posts are formed, the next crucial step is Galvanizing after fabrication. This process involves coating both the fence panels and posts with a protective layer of zinc.
| Region / Standard | Zinc Coating Requirement |
|---|---|
| China (GB/T 13912) | ≥ 85 μm (≈610 g/m²) |
| USA (ASTM A123) | ≥ 610 g/m² for wire < 5mm diameter |
| EU (EN ISO 1461) | ≥ 55–85 μm depending on base steel thickness |
| Australia / NZ (AS/NZS 4534) | W05 class: ≥ 600 g/m² |
Powder spraying
After galvanizing, the final surface treatment step is Powder Coating—also known as Powder Spraying. This process involves electrostatically applying a dry powder onto the galvanized surface of fence panels and posts, then curing it in a high-temperature oven to form a smooth, durable, and weather-resistant finish.
| Item | Specification / Standard |
|---|---|
| Coating Thickness | ≥ 60 μm (Standard) Optional: 80–120 μm (High Protection) |
| Adhesion Standard | ISO 2409: Classification 0–1 (No flaking) |
| Impact Resistance | ISO 6272: ≥ 2.5 Joules |
| Salt Spray Test | ISO 9227 / ASTM B117: ≥ 500–1000 hours |
