What material is most widely used for wire rope, with varying grades?

• A. Lang-lay ropes
• B. Splice efficiency
• C. Bird caging
• D. High-carbon steel

Answer: (D)

The material used for wire rope is steel, specifically high-carbon steel. Wire rope is made from many strands of steel wires twisted around a core, and the carbon content gives the wires the hardness, strength, and fatigue resistance needed for heavy lifting and long service life. Different grades increase tensile strength and performance, but the base material remains steel, which is why high-carbon steel is the standard choice. The other options describe rope construction or issues rather than the material itself: Lang-lay refers to how the strands are laid, splice efficiency to how well rope can be joined, and bird caging to a defect mode.
