Differences Between Wire Rope Constructions

If you know a wire rope’s specifications, you will be able to identify the strand pattern. The wire size typically determines strand patterns, the total number of strands, and the number of wires per strand. Understanding wire rope specifications will allow individuals to get the best possible ropes for the desired application. Choosing ropes for the wrong reasons (saving money, not knowing better) is a sure-fire way to waste money and time while also gambling with the health of employees and equipment. Make sure you purchase appropriate rigging supplies for your exact needs.

Standard stainless-steel wire rope specification includes:

Single Layer: six wires, of the same diameter, surround a single wire center.

Seale: these have two layers that are made up of the same number of wires that surround the core. The width for both core and outer layer wires are the same, but they do have smaller wire used for the inner layer.

Filler Wire: when a core has two separate layers of uniformed wire around. The inner layer wires number half the amount of the outer layer. Filler wires are used in the valleys to help lock inner and outer layers in place.

Combination: unique designs are creating two or more of the above patterns.

Warrington: an inner layer of wires surrounds cores with the same diameter. For this type, outer layers have two different wire diameters that alternate between small and large.
