1x19 Stainless Steel Compacted Strand Wire Rope - 316 Alloy

Compacted strand wire rope is manufactured from strands which have been compacted or reduced in diameter, by passing through a die or rollers, prior to laying the strands into a finished wire rope. The compacting process flattens the surface of the outer wires and re-forms the internal wires of the strand to increase the metallic cross-section area of the strand.
(Conceptually speaking, you can think of the compacting process as squeezing the air out from between the wires that make up a strand.)
This results in both a smoother surface at the strand crowns, and an increase in strength compared to round strand rope of the same diameter and classification.

Compacted strand wire rope is popular with racing sailboats because you can often use a smaller diameter wire while achieving the same strength - saving weight and reducing windage aloft.
Conversely, cruising sailboats can use compacted strand rigging to achieve an extra margin of safety, due to its higher strength, with the same diameter wire.

Compacted strand has also become very popular in the architectural industry for its aesthetic appeal due to its smooth, clean finish and superior luster. You'll see it used in deck and staircase railings, etc.

• Increased metal surface area on outer surface and more steel per given diameter compared to conventional round strand rope
• Approximately 30% higher breaking load than a conventional wire rope of the same diameter
• Up to 25% less stretch than a conventional wire rope of the same diameter
• Increased durability and longer service life
• Increased areas of contact between the wires for excellent crush resistance
• Can be used with mechanical end fittings, and conventional swage fittings using proper technique
