Black small coil wire

Black small coil wire (black iron wire) is an ungalvanized small coil wire made of low-carbon steel wire after annealing. Its surface is black or dark blue, and it feels smooth. It is mainly used in scenes such as building binding, hand weaving, and industrial fixing. Because it has not been galvanized, it has poor corrosion resistance, but it has good flexibility and is easy to bend, which is suitable for applications that require high ductility.

If you need a long-term durable and rust-resistant binding material, it is recommended to use galvanized small coil wire (especially hot-dip galvanized).

✅ If you need a softer, more flexible, short-term binding material, you can choose black small coil wire, but be careful to store it in a moisture-proof manner.

For different scenarios, you can choose the appropriate iron wire according to your needs to achieve the best use effect.
