Galvanized steel strands are usually used for load-bearing cables, pull wires, reinforcing cores, etc.
Optical cables are divided into metal and non-metallic models, which can be made of a single steel wire or a steel wire rope composed of high-strength steel wires. Non-metal optical cables generally use FRP.
Steel Wire Rope is a helical wire bundle that twists steel wires with mechanical properties and geometric dimensions that meet the requirements according to certain rules. The steel wire rope is composed of steel wire, rope core and grease.
