Delivery Time: 8-14 days
9-Gauge Galvanized Wire
9-gauge galvanized wire refers to low-carbon steel wire with a diameter of 3.66 mm (SWG) / 3.76 mm (BWG) that has undergone hot-dip or electroplating to apply a silver zinc coating. It is a type of thick iron wire. It possesses advantages such as corrosion resistance, tensile strength, and load-bearing capacity. It can be used in large fences, mesh welding, structural supports, etc.
Wanzhi Steel is a professional manufacturer of 9-gauge galvanized wire. Our products have a uniform and bright zinc coating, high toughness and strength, and can be used to manufacture galvanized welded wire mesh, gabion boxes, heavy-duty binding, etc. Customized coil weight and packaging are available, and OEM/ODM services are provided.

Diameter Standard SWG/BWG
| Standard Types | Corresponding diameter (approximately) |
| SWG (British Standard Wire Gauge) | 3.66 mm |
| BWG (Birmingham Wire Gauge) | 3.76 mm |
| Metric (millimeters) | 3.50 mm – 4.00 mm |
Reference Information
Theoretical weight: approximately 75.6 kg/km (based on SWG 3.66mm). This translates to approximately 13.2 meters per kilogram.
| Mechanical Properties | |
| Tensile strength | Standard annealed wire: 340～440 MPa; Cold-drawn hard wire: 550～700 MPa |
| Elongation | ≥10%～20% |
| Flexural properties | Bending 180° repeatedly |
| Torsional properties | Twisting and twisting without becoming brittle |
Relationship between tensile strength and diameter: The larger the diameter, the higher the tensile strength is generally (due to the increased cross-sectional area).
- Reference formula: Tensile strength (MPa) = Maximum tensile force (N) / Cross-sectional area (mm²).
Advantages of 9 GA HDG Wire
- Rust and Corrosion Resistance: The zinc coating isolates the wire from external media, ensuring a long service life. The strong zinc layer makes it several times more durable than black iron wire, especially excelling in humid environments.
- Toughness and Strength: The low-carbon steel base offers excellent flexibility and tensile strength, allowing for twisting and weaving. It’s suitable for manufacturing large ranch and industrial fences, and also serves as the core wire for galvanized barbed wire.
- Smooth and Aesthetically Pleasing: Our electro-galvanized wire has a bright silver-white surface, smooth and burr-free, allowing for direct binding and making it suitable for applications where aesthetics are important.
- High Cost-Effectiveness: Significantly cheaper than stainless steel wire, offering a superior long-term cost advantage. Its corrosion resistance and strength meet the requirements of most outdoor projects, making it suitable for mass production.

Application Areas
- Fencing: Main load-bearing wire of barbed wire, chain link fence, and protective mesh, suitable for grasslands, pastures, construction sites, and prison boundary fencing.
- Construction: Binding steel bars and pipes, fixing scaffolding, weaving crimped wire mesh, plastering/mortar reinforcement, heavy-duty fencing.
- Agriculture: Medium-sized animal enclosures, houses, cages, orchard and vegetable garden fencing, and crop trellis construction.
- Binding: Heavy-duty baling, lifting tool connectors, temporary fixing and support, gabion construction, reno mattresses, wire mesh, and pipe fixing.

How is the 9-gauge GI Wire Manufactured?
The base material is low-carbon steel with a carbon content of 0.05%-0.25%. The iron wire is softened through a series of processes including cold drawing, pickling, tempering, and high-temperature annealing, followed by galvanizing.
- Hot-dip galvanizing: Degreasing, pickling, and phosphating followed by high-temperature galvanizing. The coating is thick and offers strong rust resistance, but the surface finish is relatively low.
- Electro-galvanizing: Degreasing, pickling, and activation followed by electrolytic deposition of zinc. The zinc layer is thinner, the surface is bright, the coating thickness is controllable, but the corrosion resistance is relatively weaker.

Purchase Recommendations
1. Choose the wire hardness based on the application scenario:
- For load-bearing and fixing: Choose hard wire with a tensile strength ≥ 500-600 MPa, such as 8-12 gauge hot-dip galvanized wire used in construction.
- For bending: Choose soft wire with a tensile strength of 300-400 MPa, such as 18-22 gauge electro-galvanized wire used in handicrafts.
2. Choose the process based on the environment:
- For humid/corrosive environments: Hot-dip galvanizing is recommended. The thicker zinc layer provides better corrosion resistance, suitable for those with a sufficient budget.
- For indoor/dry outdoor/temporary use: Electro-galvanizing is recommended. It offers lower cost and greater precision, suitable for those seeking short-term cost control.
3. Confirm specifications:
Contact the supplier to confirm the zinc layer uniformity, actual diameter, adhesion, and actual tensile strength.
