Import Black Wire — Buy in Bulk from Supplier in China

Black wire from Rong Ke Metal Products Co.Ltd is annealed iron wire, typically produced in gauges ranging from 16 to 24 SWG, with lengths supplied in coils of 50 kg or 100 kg. The wire undergoes a controlled heating and slow-cooling process to enhance ductility and reduce brittleness, making it suitable for tying, binding, and securing applications. Surface finish is naturally oxidized, giving it a matte black appearance without additional coatings.

This product is made from low-carbon iron, with carbon content typically under 0.15%, consistent with standard industrial tie wire. The annealing process ensures consistent tensile strength across batches, usually between 350 and 500 MPa. While no certification is listed, the material composition aligns with ASTM A82 and EN 10270-1 standards for annealed iron wire used in construction. The wire resists rust longer than unannealed counterparts due to its controlled oxidation layer.

Buyers in construction, fencing, and crafts use this wire for securing rebar, bundling materials, and structural tying. It is also common in agricultural netting and DIY projects requiring flexible, strong fastening. Packaging is in waterproof paper-wrapped coils on wooden pallets. MOQ is typically one ton, and trade terms include FOB Tianjin or CIF destination, with lead time around 15 to 20 days after deposit confirmation.
