Description
Black Annealed Wire is manufactured from high-quality low carbon steel wire (Q195/SAE1008) through the process of cold drawing and thermal annealing. The annealing treatment relieves internal stress and softens the wire, giving it exceptional flexibility, ductility, and a uniform black oxide finish. It is easy to bend, twist, and tie by hand or machine without breaking, making it an economical and reliable solution for construction rebar tying, baling, packaging, agriculture, and daily binding applications.
