Binding Wire
Soft annealed low carbon steel wire, also called black annealed wire. Ultra-high flexibility for easy manual twisting and binding, no rebound after bending. Mainly applied for construction steel bar tying, cargo bundling, packaging and agricultural vine fixation.

FAQ
- Q: What is the difference between binding wire and ordinary carbon steel wire?
A: Binding wire is fully annealed soft wire with ultra-high flexibility for easy manual twisting; ordinary carbon wire is hard drawn semi-finished product mainly for secondary deep processing such as galvanizing and weaving. - Q: What is the difference between hot-dip galvanized wire and electro-galvanized wire?
A: Hot-dip galvanized wire has thicker zinc layer and better anti-rust performance for outdoor long-term use; electro-galvanized wire has thin zinc layer, smooth surface, suitable for indoor decorative mesh and low-corrosion environment. - Q: Can spring steel wire be bent arbitrarily at will?
A: No, it has high elastic hardness, repeated excessive bending will cause fatigue fracture, it is only designed for making standard elastic springs under limited reciprocating force. - Q: What is the usage of wire rod?
A: Wire rod is the raw material billet, which needs to be cold drawn multiple times to produce all kinds of finished steel wire, also widely used for making bolts, nuts, nails and other fasteners directly. - Q: Can we customize non-standard wire diameter and coil weight?
A: Yes, we accept customized diameter, single coil weight, tensile strength and surface anti-rust treatment according to customer’s drawings and production requirements. - Q: What payment terms do you accept for bulk order?
A: We accept flexible payment terms, please contact our sales team.
