For larger applications, such as garage doors and trampolines, large extension springs are preferred.  Large Extension Springs are capable of handling large loads while providing the necessary stretch to support heavy loads.

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.

Black annealed wire is a type of wire commonly used in a variety of industrial and construction applications. Black annealed wire  is known for its durability, flexibility, and corrosion resistance, making it a popular choice for a variety of projects. Black annealed wire is available in different sizes, including 12 gauge, 14 gauge and 16 gauge, each with specific uses based on its thickness and strength.
