Wire Rope Strand Construction
Seale
In this design,the outer layer has a predetermined number of large wire. Thay are laid around an equal number of small inner wires in such a manner that the outer wire lie in the valley of the under lying wires. The advantage of this form is in its more abrasive surface.
Warrington
In this design, a layer of pairs of wire(one large and one small) is laid over an inner layer of wires. The number of those in the outer layer. In this formation the strand is more roundish. It has more wearing surface.
Filler
In this design, the intermediate layer has a warrington relationship with the outer.
Warrington-Seale
In this design, the intermediate layer has a warrington relationship with the outer.
Compacted strand
Strand which has been subject to a compacting process such as drawing rolling or swaging whereby the metallic cross-sectional area of the wires remains unaltered whereas the shape of the wires and the dimension of the strands are modified.
Shaped strand
Shaped have greater surface area of steel. The shaped strand rope have about 15% greater cross sectional metallic area, hence they are stronger and have longer life.
Cross lay
Multiple operation strand construction in which the wires of superimposed wire layers cross over one another and make point contact.
Parellele Lay Rope
The lay pitch of all the wires in the strand is the same. The wires of every layer in the grooves which the wires of inner layer. The wires are in the linear contact state, and the structure of the strand is tight. So the Parallel Lay Rope has a bigger breaking force, when it is being used, it does not have quadratic quadratic bending stress between the wires of every layer, and it has good anti-fatigue character.
Compacted Strand Rope:
The wires in the strand are in the facial contact state. The metal block-coefficient of the wire rope is big, and the structure of the strand is tight. When the wire rope is being used, it does not have quadratic bending stress between the wires of every layer, and has small contact stress. It has big mating surface between the wire rope and the sheave groove. So the Compacted Rope has good antifriction, anti-extrusion and anti-fatigue character, and it is not easily distortion.
Steel Core Rope
The Steel Core Rope has a big breaking force, and a good resistance to impact, high temperature and extrusion.

Wire Ropes are commonly utilized for lifting applications across many types of industries where big machine has to be moved very frequently. It helps in performing variety of tasks requiring strength, flexibility and heat resistance. The wire rope has better strength and is resistant to heat damage.
