Basic Wire Rope Components

Wire rope consists of three basic components:

1. the wires that form the strand
2. the strands that lay around the core
3. the core which the foundation of any wire rope.

These basic wire rope components vary both in complexity and configuration to produce a wide range of wire ropes for specific purposes and applications.

Wires can be made from a variety of materials, the most common being high-carbon steel. This is available in a variety of grades which are pre-determined in the manufacture of the rope based on the intended use and application of the wire rope.

Strands are made up of two or more wires, laid in any one of the many specific geometric arrangements, or in a combination of steel wires with some other materials such as natural or synthetic fibres.

The Core is the foundation of a wire rope; it is made of materials that will provide proper support for the strands under normal bending and loading conditions. Core materials include fibres (hard vegetable or synthetic) or steel. A steel core consists either of a strand or an independent wire rope.

The three most commonly used core designations are: fibre core (FC), independent wire rope core (IWRC), and wire strand core (WSC).

Conventional wire ropes are used in a wide range of applications: lifting, hoisting, lashing, towing, mooring, hauling, logging, drilling, etc. A wide range of sizes and constructions are available for various usages. Different constructions have different characteristics suitable for different uses depending on the design’s requirement of the strength, fatigue resistance, wear resistance, flexibility and abrasion resistance.

 

How to Measure Wire Rope

Measure the circle just touching the extreme outer limits (crown) of the strands.

Yachting Wire Rope

Yacht rigging wire ropes are generally supplied in stainless steel with the odd use of galvanised. Stainless steel wire ropes used for yacht rigging generally range from 1.5mm up to 14mm. Popular construction types include 1×19 for stays and shrouds and 6×19 for more flexibility in running back stays, halyard tail ends and winch ropes. PVC coated wires are also often used.

Hampidjan NZ Ltd yacht rigging services include full rigging and swage fitting, braid to wire splicing, rope splicing and traditional hand splicing.

A full range of stainless yacht rigging fittings are available including shackles, eye bolts, rigging screws, clips, rings, thimbles, links, blocks, grips and insulators as well as a full range of braided ropes and dyneema ropes – DynIce 75.

 

Stainless Steel Wire Rope

Stainless steel wire rope is used in many applications. Designed for both presentation and performance stainless steel wire rope is suited to environments generally exposed to the elements while maintaining its high quality look and feel as well as its structural integrity.

Not only used on yachts for stay wire and general rigging, stainless steel wire is used for many building applications such as Balustrade on building sites and homes.

Hampidjan NZ Ltd supplies a large range of stainless steel wire rope types and sizes suitable to many different applications. All associated stainless steel fittings are also available.

 

Stay Strand Wire Rope

There are many applications for stay strand wire ropes. More popular sizes range between 5mm to 12mm using either galvanised or stainless steel wire.

A common use for galvanised stay wire is in the electricity industry using the wire to stay power poles and tower structures. This is normally between 7mm and 10mm galvanised 1×7 wire rope.

Another common use for galvanised stay strand wire is in the horticultural industry e.g Hop Gardens
Hampidjan NZ Ltd supplies a wide range of sizes of stay strand wire for various uses and applications. Wire can be ordered at any size and length and can be delivered on reels or in simple coils of varying sizes.
