Products Description
A low-carbon steel wire processed through annealing and black oxide coating, offering superior flexibility, corrosion resistance, and aesthetic uniformity. Widely used in construction, crafts, agriculture, and industrial bundling.
Products Advantages
Key Advantages of Black Annealed Iron Wire
Superior Flexibility
Softened through controlled annealing, making it easy to bend, twist, and knot without breaking. Ideal for manual handling and tight bundling.
Enhanced Corrosion Resistance
Black oxide coating + light oil film provides better rust protection than bare wire (optional wax coating for humid environments).
Smooth & Safe Surface
No sharp edges or scale residue, reducing worker injuries and damage to bundled materials.
Cost-Effective
Lower production cost than galvanized or PVC-coated wires, offering a budget-friendly solution for high-volume uses.
Competitive Edge vs. Alternatives
✔ vs. Galvanized Wire: Softer, cheaper, and no zinc spalling.
✔ vs. Bright Wire: Better rust resistance and less glare.
✔ vs. PVC-Coated Wire: More economical for indoor/dry uses.
Products Applications
onstruction & Building
Rebar Tying: Soft and flexible, ideal for securing steel bars in concrete structures.
Drywall Framing: Used to hang and stabilize drywall tracks.
Wire Mesh Fixing: Helps secure fencing, gabions, and welded mesh.
FAQ
Q1: What is the difference between black annealed wire and galvanized wire?
Black Annealed: Softer, more flexible, and cost-effective but has moderate rust resistance.
Galvanized: Harder, more rust-resistant (zinc-coated), but less bendable and more expensive.
Q2: Does black annealed wire rust?
Yes, but the light oil/wax coating slows rusting. For outdoor use in humid areas, wax-coated or PVC-coated wire is recommended.
Q3: Can black annealed wire be used for electric fencing?
No, it is not conductive enough for electric fences. Use galvanized or aluminum wire instead.
Q4: What is the standard coil weight?
Typically 25kg/coil, but customized weights (e.g., 10kg, 50kg) are available.
Q5: How does annealing improve the wire?
Annealing softens the wire by heating and slow cooling, making it more ductile and easier to work with.
Q6: Can I get black annealed wire in different thicknesses?
Yes, common diameters: 0.5mm–4.0mm (custom sizes available).
Q7: Is it suitable for high-temperature environments?
No, prolonged exposure to >200°C can weaken the wire. For high heat, consider stainless steel wire.
Q8: What packaging options are available?
Coils (25kg), Pallets (500kg), Spools (custom lengths), PVC sleeves (extra protection).
Q9: Can the wire be cut to specific lengths?
Yes, pre-cut lengths (e.g., 1m, 3m) are available for bulk orders.
Q10: How do I prevent rust during storage?
Store in a dry place, use desiccant packs, or apply light oil if storing long-term.
