The production of black annealed iron wire begins with high-carbon steel wire rods. These rods are heated and then allowed to cool in a controlled environment, a process known as annealing. This process not only improves the ductility of the wire but also reduces its hardness, making it easier to work with. The black color of the wire comes from the coating of iron oxide that forms during the manufacturing process, which provides a degree of corrosion resistance.

Furthermore, safety precautions should always be observed when cutting welded wire mesh, as sharp edges and flying debris pose potential hazards. Protective gear such as safety glasses, gloves, and ear protection should be worn, and proper ventilation is recommended when using power tools to mitigate the risk of dust and fumes.

Welded wire mesh, prized for its strength, durability, and versatility, has long been a staple material in various industries. However, its rigid structure has traditionally posed challenges when it comes to bending and shaping.
