Black Steel Wire

There is a coil of black annealed wire on the white ground.

Annealed Wire For Agriculture, Construction and Handicrafts

Black steel wire, also called black annealed wire, black iron wire, is made of carbon steel wires and produced through thermal annealing. The black annealed wire is softer, more flexible, uniform softness than traditional carbon steel wire.

The black annealed wires are widely used in mesh weaving, binding wire in constructions and agriculture. The black annealed wires can be treated with galvanized, powder coating or PVC coated for more durable and corrosion resistance performance.
