If you want to find a reliable wire rope supplier, we are the right one you needed, we can help you and your business grow and succeed.
Wire Ropes
Wire ropes can be seen everywhere around us, they are made of strands or bundles of individual wires constructed around an independent core, suitable for many applications because of the wide array of end fittings attached to enable them not only to be fitted to almost any anchor point but also to adjust them to the required tension, ideal for construction, industrial, fitness, commercial, architectural, agricultural and marine rigging applications.

Wire rope can be seen everywhere around us, it is made of strands or bundles of individual wires constructed around an independent core, suitable for hoisting, towing, and anchoring heavy loads.
Wire rope is specified by the number of strands in the rope, the number of wires in each strand, and the strands are then twisted to form a rope construction.
Wire
Wires are the main component of wire rope and they are twisted together around a central wire to form strands.
Wire Rope Strand
The strand is made up at least two wires twisted in a specific arrangement, then the strands are helically laid together around a core of the rope.
Wire Rope Core
The wire rope core is in the center of the rope and provide the rope stability, it is the foundation for the wire rope. Cores can be supplied with natural or synthetic fibers and steel core. For example, the 6×19 FC wire rope means that the rope has 6 strands, and there are 19 wires in each strand, the numbers 6×19 is followed by a letter combination, it means the core of the wire rope, FC means fiber core.
Fiber core= FC, PC or HC
Fiber cores are made of natural material, such as sisal, or hemp core wire rope(HC) or a synthetic fiber such as polypropylene core wire rope(PC).
Steel core= IWRC(Independent wire rope core) and WSC(wire strand core)
IWRC is commonly manufactured from 7 strands, while the WSC is manufactured from either 7 or 9 wires. Steel cores have a higher resistance to drum crushing and where less stretch and more strength is required.
Different Wire Rope Constructions
The 6×19 FC wire rope means that the rope has 6 strands, and there are 19 wires in each strand, however, 6 x 19 wire rope may not reflect the actual construction, for 6 x 21 wire rope, and 6 x 26 are designated as being in the 6 x 19 classification, despite none of their constructions contain 19 wires.
Here below is the table to show some of the most common wire rope configurations arranged in specific classifications.
| Classification | Outer Strands | Wires/Strand |
| 6×7 | 6 | 3-14 |
| 6×19 | 6 | 15-26 |
| 6×37 | 6 | 27-49 |
| 6×61 | 6 | 50-74 |
| 6×91 | 6 | 75-109 |
| 7×19 | 7 | 15-26 |
| 7×37 | 7 | 27-49 |
| 8×7 | 8 | 3-14 |
| 8×19 | 8 | 15-26 |
| 8×37 | 8 | 27-49 |
| 8×61 | 8 | 50-74 |
There are many different wire rope grades, the higher grade, the higher min breaking strength, commonly the grades of wire rope are available include Improved Plow Steel (IPS), Extra Improved Plow Steel (EIPS), Extra Extra Improved Plow Steel (EEIPS), and metric wire rope grades can be designated as 1770n/mm²(Improved Plow Steel), 1960n/mm²(Extra Improved Plow Steel) and 2160n/mm²(Extra Extra Improved Plow Steel).
There are main three protective coatings on the wire rope, zinc-coated (galvanized) wire rope for harsh environment, uncoated steel (bright) wire rope for most running supplied, and stainless steel wire rope for marine and architectural applications.
The type and direction of lay wire rope mean the wires are laid around the strands(regular lay or lang lay) and the direction in which the strands are laid around the core(a right or left hand).
Regular lay
Regular lay is also referred to as ordinary lay. The strands are twisted in one direction, either left or right across the core and the wires are laid in opposite direction to the lay of the strands, which causes the finished product to appear like the wires are running parallel to the axis of the rope.
The regular lay wire rope is more flexible and carries better resistance to crushing forces and is more naturally rotation-resistant and spool better on a drum than lang lay wire rope.
Lang lay
The lang lay wire rope indicates that the wire lay and strand lay around the core in the same direction, either right or left and causes the finished product to appear with the wires to form an angle with the axis of the rope. Thes lang lay ropes are generally more flexible and have increased abrasion resistance leading to a longer lifespan than regular lay ropes, which can be used in construction, excavating, and mining applications.
Wire ropes can be seen everywhere around us, they are made of strands or bundles of individual wires constructed around an independent core, suitable for construction, industrial, fitness, commercial, architectural, agricultural, and marine rigging applications.
In this article, we will shortly describe how to produce the wire ropes.
- Wire rod
Wire rod is made from high carbon steel wires(0.35 to 0.85 percent carbon) in a hot rolling process of a required diameter, usually from 5.5mm to 8 mm.
- Surface treatment
Descaling dust and rust from the outer surface of the wire rod to facilitate the drawing process.
- First Drawing
Wire rod is drawn to the required diameter by the 1st drawing machine after descaling dust and rust, adding mechanical properties suitable for application.
- Patenting
The first drawn wires are transformed into a heat treatment furnace to obtain the required microstructure and to facilitate drawing.
- Second Drawing
The patented wire is drawn for the final required size of wire.
- Stranding
Positioning the wires different or the same size lay in multiple layers and same direction, or cross lay and diameter is maintained by one-third of the rope size.
- Closing
After completing the set of strands, these strands are laid on a core (Fiber or Steel ) which produces the rope of the required diameter.
So in theory, it is very simple to manufacture wire ropes. However there are many more details that must be closely monitored and controlled, and this requires time and experienced personnel since it is a super complicated project you cannot imagine.
