Six industries.Six definitions of“strong enough”.

Peak break strength is rarely what governs a specification. Creep does, or UV, or termination efficiency, or the energy a parting line releases. Each of these pages starts with the constraint that actually decides the job.

Marine & Yachting

Running rigging, ground tackle and dock lines that survive the season.

Typical design factor

5:1 to 8:1 for running rigging; 8:1 or higher for ground tackle

Offshore & Mooring

Permanent moorings, hawsers and pendants under continuous load.

Typical design factor

Per OCIMF MEG4 and the operator's mooring analysis — commonly 2:1 to 3:1 on MBL for ship mooring

Crane & Lifting

Slings, pendants and winch lines where the load is over someone's head.

Typical design factor

5:1 minimum for general lifting; 7:1 or higher where personnel work beneath the load

Arborist & Forestry

Climbing lines, rigging lines and lowering systems for working aloft.

Typical design factor

10:1 for climbing lines; 5:1 for rigging and lowering lines

Rescue & Access

Life-safety rope built to a standard and documented to prove it.

Typical design factor

15:1 per NFPA 1983 General Use

Utility & Transmission

Pulling lines, guys and stringing rope for the grid.

Typical design factor

5:1 for pulling operations; higher for permanent guying per structural design
