Strands and cables are highly engineered products and are ideal for applications requiring more strength and flexibility than a monofilament wire can provide. They are often utilized for complex constructions or processes in order to enhance the following: fatigue life, strength, flexibility, torque, stiffness, and smoothness. Strands are formed by wrapping several filaments of wire together to form a single strand. When several of these strands are wrapped together, they form a cable. Strands and cables are available on spools, as discrete lengths and as mechanical assemblies.
