Product Details

Premium Black Iron Wire and Black Annealed Wire are essential high-performance binding materials engineered for maximum versatility and durability. By utilizing a specialized heat treatment annealing process, we transform standard steel into a soft, pliable wire that maintains exceptional tensile strength. Available in various forms including coils, spools, and large packages, our wire can be further customized through straightening and cutting to meet specific industrial requirements.

Produced by Hebei Jinjiu Metal Products Co., Ltd., our wire solutions are designed for critical applications in construction, agriculture, and industrial packaging. As a leading OEM and ODM supplier with over 20 years of expertise, we ensure each batch undergoes rigorous testing for uniform diameter, oxidation resistance, and consistent mechanical properties, providing professional-grade reliability for global infrastructure and logistics projects.

Frequently Asked Questions

Q: What is the main difference between black iron wire and black annealed wire?

Black annealed wire undergoes a heat treatment process that makes it significantly softer and more flexible than standard black iron wire, making it ideal for binding and tying without snapping.

Q: Can these wires be used for outdoor agricultural purposes?

Yes, our black annealed wire is specifically designed for outdoor use, including hay baling and trellising, due to its weather resistance and durability.

Q: Do you provide custom sizes for industrial projects?

As a professional OEM and ODM supplier, we offer a wide range of BWG and SWG sizes and can customize tensile strength and coil dimensions to meet your project specifications.

Q: How does annealed wire improve construction efficiency?

Its pliability allows for faster rebar tying and concrete reinforcement, reducing labor time and minimizing material waste on the job site.

Q: Is the wire coating uniform across bulk orders?

Yes, every batch undergoes strict quality inspection to ensure uniform black coating and roundness, preventing flaking and ensuring consistent performance.

Q: What packaging options are available for shipping?

We provide various packaging including 1kg rolls, as well as customized coil, spool, or large package wire depending on your logistics requirements.
