Packing: 25_200kg/coil plastic inside and hessian / weavig bags outside.
Black annealed wires, also called annealed wire, soft annealed wire or annealed steel wire, ismade by cold drawing process, anaerobic annealing, drawn into filaments, and then the annealing process again. Because of the annealing process, the wire is strong and flexible.It is widely used in construction and tied wire. It is also a major raw material for weaving galvanized wire and nets.

 Anneal is to low the tensile strength of wire. The stove is solid and built with red bricks. The architecture of anneal stove is cuboid.

Different thickness of wire require different temperature. Range is from 700°C to 900°C. Output of the anneal stove, the tensile strength is 350N~400N.
