Yes. We can customize steel spools for wire packaging according to your specific dimensions or engineering drawings. Steel spool packaging is a non-standard customization service, so a minimum order quantity is usually required. Our standard packaging methods are bulk coils or plastic spools. If you require steel spool packaging, please provide detailed dimensions or drawings when placing your order.

Wire rod, as raw material, is first hot-rolled and then cold-drawn into wire. This results in wire rod having a larger diameter, while wire has a smaller diameter. Furthermore, wire can be customized in terms of properties, while wire rod cannot.

These are common delivery states for wire. Cold-drawn wire has the highest strength, and its tensile strength can be adjusted through different heat treatments. Hard wire has the highest strength, followed by semi-hard wire, and soft wire has the lowest strength.

Because wire has a small diameter and continuous length, it is easily oxidized when heated in a conventional furnace, forming a black scale on the surface that is difficult to remove with pickling. Therefore, we use a continuous bright annealing furnace. The furnace chamber is filled with a protective gas (such as hydrogen or ammonia decomposition gas), and the wire is heated and kept at a constant temperature while moving forward, without contact with air throughout the process. The resulting wire has a bright surface and does not require further acid pickling.
