The galvanized iron wire serves as a crucial component in the utilities and infrastructure sector, where its strength, durability, and corrosion resistance are essential for various applications. One prominent use of this wire is in the installation of electrical and communication lines, providing robust support for cables and wires that are integral to modern infrastructure systems.

Black annealed wire is also utilized as a sheathing material in cable manufacturing. The sheathing process involves wrapping the wire around the cable to create a protective layer that shields the internal components from physical damage, environmental factors, and wear. This protective layer is vital for ensuring the longevity and reliability of the cables, especially those used in harsh environments or exposed to external mechanical forces. For example, in telecommunications and power transmission, cables often run through underground conduits or are exposed to outdoor elements. The black annealed wire sheathing helps to prevent abrasion, cuts, and other forms of damage, thereby extending the lifespan of the cables.
