White Annealed Wire Rewound Coils China Factory and Professional Suppliers
White Annealed Wire Rewound Coils represent a premium advancement in steel wire technology, specifically engineered for high-demand bundling and construction applications. Also known as oxygen-free or vacuum annealed wire, this product is characterized by its distinct white-gray appearance and a surface entirely free of impurities. By utilizing a controlled nitrogen atmosphere during the heat treatment process, we eliminate surface scale, resulting in a wire that offers superior softness and significantly higher elongation than standard black annealed wire.
Designed for efficiency and environmental sustainability, our white annealed wire is non-galvanized and eco-friendly, ensuring it is harmless to both users and the environment. Its high ductility and consistent smoothness make it the ideal choice for automated bundling machines and precision industrial components, such as automotive airbag accessories. Whether used for garden bundling or heavy-duty construction steel bar tying, these rewound coils provide a seamless, tangle-free experience that optimizes labor productivity and reduces operational costs.

Frequently Asked Questions
White annealed wire is not galvanized; its color and finish are achieved through a controlled nitrogen annealing process, making it environmentally friendly and free of zinc coatings while remaining highly ductile.
Our rewound coils feature a single start and are smooth to use without threading. This prevents tangles during high-volume bundling, significantly saving labor time and reducing material waste.
Yes, tensile strength depends on the steel grade and specific annealing parameters. Our Engineering Department can work directly with you to customize the strength and elongation required for your project.
It is highly effective in construction (steel bar bundling), automotive manufacturing (airbag accessories), and high-end gardening products where surface purity and flexibility are critical.
Yes, because it is scale-free and lacks the loose oxide layer found in black annealed wire, it minimizes staining and provides a cleaner finish for the bundled assembly.
Our standard large coils are typically packed between 500kg and 1000kg per coil to balance ease of transport with operational longevity.
