Wire rope consists of three basic components: 1) the wires that form the strand; 2) the strands that lay around the core; and 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 usage. 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.


The size of a wire is the Diameter of the circle which will just enclose all of the strands. The correct method is to measure over any pair of opposite strands.

 


Commercial fishing fleets use a variety of wire ropes in purse seining and trawling operations. Nelrig Wire Rope Services provides commercial fishing operators with a wide variety of high quality reliable wire ropes for their fishing vessels.










Constructed using specialised methods and materials, Nelrigs fishing wire ropes are purpose built to last and perform in the corrosive and hard wearing environment of commercial fishing. All Nelrigs wire ropes are built to standards of quality and specification through strict adherance to ISO9000 and British Standard specifications. Click here for more information on our certifications and standards.

Common construction types for commercial fishing include; three strand 3x19 and 3x26 and six strand 6x19 and 6x26 galvanised wire ropes.. Depending on customer needs these wire ropes may have a fibre or steele core and either be standard construction or compacted for increased strength and durability.

Nelrig supply wire rope of any construction and size as the need may be. The most common sizes of fishing wire ropes range from 8mm up to 38mm diameter. Any requirements outside of common sizes and construction can be catered for by special order.



 


Forestry and Logging operations use a wide range of wire ropes and chains. Straw lines, guy wires and main ropes for logging yarders vary in size and construction based on the size and nature of the individual logging operations.















Mainlines for logging operations for example are commonly used with a construction of 6 strand compacted wire to maximise strength and durability. The wire rope is compacted down to a smaller size during the manufacturing process to provide extra strength at a smaller diameter. This reduces the volume of wire rope the logging operators are required to handle while maintaining a safe working rig with the extra strength.

Nelrig supplies wire ropes to logging operators in a wide range of sizes and construction types. Any requirements outside of the normal logging wire rope specifications can be catered for by special order. All Nelrigs wire ropes are built to standards of quality and specification through strict adherance to ISO9000 and British Standard specifications.

Ski fields around the world rely on specialised high quality wire ropes to facilitate the many different types of chair and ski lifts. Ranging in sizes from 10mm to 60mm, these wire ropes are highly specialised and rely on specific construction, installation and maintenance methods to ensure only the highest of quality product is used.

Given the safety requirements of wire ropes used on ski field machinery, the manufacturing of these wire ropes is restricted to those manufacturers that maintain strict quality control and build to specific international standards.

Wire ropes used in these settings are normally a low stretch wire rope facilitated by a lubricated platicised centre core.

Ranging in a variety of sizes, one common construction is a six strand lo stretch compacted wire rope with the core strands being infused with a plastic coating to minimise internal deterioration..




 




Power cranes throughout New Zealand demand a wide range of specialised wire ropes designed specifically for crane usage. The reliability and performance of crane wire rope is an integral part of the high safety standards set by New Zealand power crane operators and owners.

Wire ropes for cranes range from smaller diameter IWRC non-rotating wires such as a 19x7 IWRC Non-Rotating wire to larger diameter specialised wire ropes with plastic infused cores such as the Teufelberger QS 816 V Perfekt type of compacet wire rope designed for 100 tonne + cranes.



Nelrig has access to all major brands and types of specialised crane wire rope and can provide specific products to suit any requirements or standards.



 



Yacht rigging wire ropes are genarally 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 1x19 for stays and shrouds and 6x19 for more flexibility in running back stays, halyard tail ends and winch ropes. PVC coated wires are also often used.

Nelrig yacht rigging services include full rigging and swage fitting, braid to wire splicing, rope splicing, traditional hand splicing as well as serving stays and shrouds made and repaired accurately.

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




 



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.



Nelrig supply a large range of stainless steel wire rope types and sizes suitable to many different applications. All associated stainless steel fittings are also available.



 



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 1x7 wire rope.
Other larger applications of stay strand wire include cable bridges that can use groups of individual stay strand wires that will act together as a beam or use larger diameter stay wires that in fact suspend from towers as in the suspension bridge design.

This type of wire construction ensures that the wire maintains its integrity while under constant tension effectively becoming "rods" of steel while maintaining flexibility so as to allow for movement without destabilising.

Nelrig supplies a wide range if sizes of stay strand wire for various used and applications. Wire can be ordered at any size and length and can be delivered on reels or in simple coils of varying sizes.
