Information about wires & ropes

Steel wire ropes and their construction:

A strand consists of one or several layers of rope wires, which are being twined helix-shaped around a core. A strand rope consists of one or more layers of strands. The core may be made of fibre or of standard wires, a steel core (fibre cores are made of natural or synthetic fibre).

Ropes - twisted or braided?
