Important - read first This document is provided for selection guidance only. Values are nominal and subject to manufacturing tolerance. Chemical resistance and load data depend on the exact medium, concentration, temperature and support conditions of your application. Confirm the final specification with us before ordering.

28 constructions, 484 diameter and load data points, from 1 mm to 60 mm. Values follow GB/T 20118-2006 unless stated otherwise.

1 . How to read this document

Find the construction you need - for example 6x36 IWRC, or 35x7 rotation resistant.
Match the diameter to the minimum breaking load you require. Weight per metre is given so you can calculate rope mass and freight.
Two wire grades are listed where available: 1770 MPa and 1960 MPa. The higher grade gives a greater breaking load at the same diameter.
Surface finish is bright or galvanized. Specify galvanized for outdoor or corrosive service.
MBL is the minimum breaking load of the rope as a whole, before termination efficiency. Apply your own safety factor on top.

5 . From MBL to safe working load

A working load limit is derived from the MBL by applying a safety factor. The factor depends on the application and the governing standard.

Lifting and slinging: typically MBL / 5
Mooring and general pulling: typically MBL / 4 to MBL / 5
Static guying where no personnel are at risk: typically MBL / 3
Terminations reduce capacity: a spliced eye or a swaged fitting does not reach 100 per cent of the rope MBL. Use the efficiency stated by the fitting supplier.

6 . Ordering information

State construction (for example 6x36 IWRC), diameter, grade and surface (bright or galvanized).
State the length and the packing: coil, wooden reel or cut lengths.
State whether a breaking load certificate is required, and whether third-party testing is needed.
Standards we work to: ISO 2408, EN 12385, ASTM A1023, GB/T 20118.
