Black Wire
Our black wire is made from both hard drawn and the softest annealed wire .
Hard drawn wire is is formed via the process of wire-drawing, coiling, and anti-rust oil spraying. The black drawn wire is more economic compared with annealed wire, it is a kind of hard drawn carbon steel wire, which is a suitable material of iron nail, wire mesh, craftwork, and so on
Soft annealed wire is obtained by means of thermal annealing, then offers excellent flexibility and softness through the process of oxygen free annealing. It is widely used as tie wire or baling wire in construction and daily binding.
