Uncoated fiber core wire rope comes on a reel and is used for a wide variety of applications. Uncoated (also called bare or bright) wire rope is a common material type that has strength. Fiber core wire rope has strands of wire formed helically around a fiber core. Fiber core wire rope provides flexibility for support of movement, but is less crush-resistant than strand or wire rope core. This wire rope comes on a reel for ease of operation. Wire rope, also called wire cable, is an assembly of wire strands formed helically around a central core. It is used for pulling, lifting, rigging, hoisting, and motion-control applications most commonly found in the manufacturing, marine, oil, mining, fiber-optic, aircraft, automotive accessory, and construction industries. A combination of characteristics such as material, finish, construction, diameter, length, and breaking strength combines to give each rope its performance ability. Wire rope materials are selected for properties such as strength, elasticity, conductivity, and chemical- and weather-resistance. For strength purposes, most wire rope is made of bright (uncoated or bare) wire. However, it is also produced in a variety of finishes, such as polypropylene (PE), vinyl (PVC), or nylon. These coatings can increase overall durability and strength, and allow for specific use. The breaking strength for wire rope is the strength at which new wire rope will fail under a stationary load. Breaking strength is not considered safe working load (SWL) limit.
