High Quality Black Iron Wire Factory China Leading Suppliers of Hard Drawn and Annealed Wire
Our Black Iron Wire is engineered from premium low-carbon steel and iron wire rods, providing a versatile and cost-effective solution for industrial and construction applications. We specialize in two primary variants: high-strength Black Drawn Iron Wire, ideal for mesh weaving and fencing, and flexible Soft Black Annealed Iron Wire, specifically designed for superior binding performance in construction projects.
By utilizing advanced wire-drawing and oxygen-free annealing processes, we ensure each coil maintains exceptional structural integrity. To maximize service life, all our black iron wires are treated with a professional anti-rust oil spray, offering an economical yet durable alternative for those requiring high-quality tying, nailing, or craftwork materials.
