Premium Black Iron Wire China Suppliers | Industrial Factory for Hard Drawn Annealed Wire
Our premium Black Iron Wire is engineered from high-quality low carbon steel wire and iron wire rods, providing a versatile and cost-effective solution for industrial and construction needs. Available in two primary specifications—Black Hard Drawn Wire and Soft Black Annealed Wire—each is processed with professional anti-rust oil spraying to ensure durability and resistance to corrosion in demanding environments.
Whether you require the high tensile strength of hard drawn wire for mesh weaving and nail production, or the superior flexibility of oxygen-free annealed wire for construction binding, our products meet rigorous industry standards. With a wide range of gauges from BWG8 to BWG34, we provide tailored cutting, coiling, and packaging options to streamline your operational efficiency.
