Premium Black Iron Wire Factory Leading China Suppliers of Hard Drawn Annealed Wire
Our premium Black Iron Wire is engineered from superior quality low-carbon steel wire and iron wire rods, offering a versatile solution for industrial and construction needs. We specialize in two distinct variants: Black Drawn Iron Wire, a hard-drawn carbon steel wire ideal for mesh weaving and fencing, and Soft Black Annealed Iron Wire, designed specifically for maximum flexibility and binding efficiency.
Combining cost-effectiveness with high durability, our wires are treated with specialized anti-rust oil spraying to ensure long-term stability. Whether you require high-tensile strength for industrial nails or extreme softness for construction tie-wire, our precision manufacturing process guarantees consistent diameters and superior mechanical properties across all gauges from BWG 8 to BWG 34.

Frequently Asked Questions
Black drawn wire is hard-drawn carbon steel used for rigid applications like nails and mesh. Annealed wire undergoes a thermal process to make it soft and flexible, making it ideal for binding and tying in construction.
All our black iron wires are treated with anti-rust oil spraying and packed in protective materials such as wax paper, PVC bags, or PE film to prevent oxidation.
Yes, besides standard coils, we can process the wire into straightened cut lengths or specialized U-type wires according to customer specifications.
The most popular sizes for sale and industrial use are BWG 16, 18, 19, 20, and 22.
We use super quality low-carbon steel wire or high-grade iron wire rods to ensure a balance of strength and processability.
We offer various options including gunny cloth, PVC woven cloth, Hessian cloth, and wooden pallets to ensure secure transportation for weights ranging from 10kg to 800kg per coil.
