Which type of stranded rope has one size wires on the outside layer and another size wires in the next layer?

Seale is the type of stranded rope that features different sizes of wires in its construction, specifically with one size on the outer layer and another size for the inner layer. This design provides a balance between strength and flexibility, making Seale ropes particularly well-suited for applications where durability is essential. The alternating pattern of wire sizes helps to enhance the rope's resistance to abrasion and wear while retaining a degree of flexibility.

In contrast, Warrington ropes typically employ three different wire sizes, but they alternate differently, which can affect their performance characteristics. Twisted ropes are known for their simplicity and have uniformly sized strands twisted together rather than layered with varying sizes. Parallel ropes may refer to construction methods where the wires run parallel rather than being stranded, which does not align with the characteristics described in the question. Each type of rope has its specific uses, but Seale's unique construction is what makes it suitable for the description provided.
