Black Annealed wire, also called black wire, comes in the form of coil wire or cut wire.

Mostly used in construction or daily use as binding material.

Annealed Wire is made of carbon steel wire, used for weaving, baling in general. Applied for home use and the construction.
Annealed wire is obtained by means of thermal annealing, endowing it with the properties it needs for its main use - setting. This wire is deployed both in civil construction and in agriculture. In agriculture annealed wire is used for bailing hay.
