Import Annealed Iron Wire — Buy in Bulk from Supplier in China

Annealed iron wire from Shijiazhuang Rongke Metal Products Co.Ltd. is a low-carbon steel wire softened through annealing to improve ductility and reduce internal stresses, making it ideal for industrial binding and construction applications. The supplier, based in Hebei, China, produces the wire in coil and cut lengths, with the material’s flexibility retained through controlled heat treatment. Its black finish, a result of the annealing process, provides a uniform surface suitable for further processing or direct use.

The wire is manufactured from low-carbon iron, typically with a carbon content below 0.15% to ensure high ductility and weldability. Standard diameters range from 0.5 mm to 6.0 mm, with typical tensile strengths between 300 and 500 MPa, depending on the gauge. Surface quality is critical, as the annealing process removes scale and improves smoothness, reducing friction during handling. Common industry standards for annealed iron wire include ASTM A82 or EN 10270, which define mechanical properties and dimensional tolerances.

Primary applications include construction tie wire for reinforcing bars, fencing, and industrial binding, where its malleability allows for tight knots without breaking. The wire is also used in agricultural baling, packaging, and as a raw material for nails and staples. Buyers should confirm the supplier’s ability to provide specific gauges, coil weights, and surface treatments, as these vary by project requirements. The product is typically supplied in coils weighing 50 kg to 500 kg, with custom lengths available upon request.

Shijiazhuang Rongke Metal Products Co.Ltd. is an imported-tier supplier based in the Beipengzhuang Development Zone, Jinzhou, Hebei Province, China. The company specializes in metal wire products, with annealed iron wire as a key offering. Its harbor trust tier and zero recorded response rate indicate that direct engagement may be required to confirm operational details such as production capacity and lead times.

The supplier’s profile does not specify certifications, export history, or quality control processes, so buyers should verify compliance with international standards like ISO 9001 or SGS directly. The absence of response metrics suggests that pre-order communication is essential to assess reliability. The supplier’s location in a development zone may offer logistical advantages for bulk shipments, but this should be confirmed with the supplier.
