1X7 strand wire rope consists of one (straight) center core wire, and six wires helically stranded around the core, with diameters ranging from 1/8" – 5/8". The construction of 1x7 strand yields minimal stretch, and this basic strand is used to make 3X7 and 7X7, and 7X19 cable.
Galvanized wire rope is dipped in molten zinc to form a thick layer of zinc coating before the wire is drawn through dies—to reduce diameter and increase tensile strength. At the same time, the zinc coating bonds to the steel wires and compresses to form a more durable layer to protect the steel from corroding, thus maintaining more wire rope strength and wire rope load capacity over longer durations.
Common applications include fencing applications, guying applications, bracing & tensioning, and use in the metal building industry. Also available in USA-made.
