Premium Black Annealed Rewound Wire Coils Factory and Suppliers in China
Our Black Annealed Rewound Wire Coils are premium-grade industrial solutions engineered from high-quality low carbon steel. Utilizing a specialized oxygen-free annealing process, these wire coils achieve exceptional flexibility and softness, making them the ideal choice for demanding binding and tying applications across the construction and industrial sectors.
By employing a rigorous high-temperature calcination process at 1000 degrees Celsius followed by a controlled cooling rate, we eliminate internal residual stresses and refine the grain structure. This ensures a stable size, reduced deformation, and superior machinability, providing buyers with consistent elongation and bendability for efficient operational performance.

Frequently Asked Questions
We use high-quality Q195 low carbon steel wire as the production basis to ensure the optimal balance of strength and ductility.
Our oxygen-free annealing at 1000°C reduces hardness, improves machinability, and eliminates residual stress, making the wire softer and more flexible.
They are primarily used as tie wire or baling wire in construction, industrial packaging, park maintenance, and general binding operations.
While samples are usually delivered within 7 days, bulk orders typically take between 20 to 40 days after the deposit is received.
Yes, our black annealed wire can be processed into coil wire, spool wire, or large package wire depending on your specific project needs.
We generally accept a T/T 30% deposit with the balance against the B/L copy, or 100% L/C at sight for larger wholesale orders.
