Black Binding Wire

Black binding wire is the annealed wire that is made from Q195 low carbon steel wires. It is widely used in the construction areas.

Annealed wire for civil construction:

Annealed wire is made from Q195 low carbon steel wires and is always packed in coils. It is widely used in construction areas. Compared with other iron wires, it will accept an extra production process - annealing. This makes it quite soft and easy to be used as the binding wires.

Package: coils, plastic inside and woven bag outside.

The annealing of bare wire (wire which has simply been drawn) can be carried out in batches (bell-type furnace) or in line (in-line furnace).


Annealed wire is stored in coils or spools of a varying weights and dimensions depending on the purposes for which it is intended and the needs of clients. The product does not usually have any type of protective lining, paper or plastic. We offer two kinds of annealed wire, bright annealed and black annealed wire. Black annealed wire gets its name from its plain black color.

Soft annealed wire offers excellent flexibility and softness through the process of oxygen free annealing.

Packing: Spools, coils.
Wire Materials: Iron wire or carbon steel wire.
Wire Diameters: Similar to galvanized iron wire, from 5mm to 0.15mm (wire gauge 6# to 38#).
Uses: Black annealed wire is mainly processed into coil wire, spool wire or big package wire. Or further straightened and cut into cut wire and U type wire. Annealed wire is used as tie wire or baling wire in building, parks and daily binding.
