1×19

1×19 is a designation used in wire rope construction to describe a specific single-strand rope. It denotes that the rope consists of one strand containing 19 individual wires, typically laid around a central core that can be steel or fiber. The result is a relatively simple and straight forward rope with moderate stiffness compared with more complex multi-strand constructions.

In practice, a 1×19 rope is more rigid and less flexible than multi-strand alternatives such as 7×19 or 7×7. This reduced flexibility can limit its suitability for dynamic or highly curved applications, but it offers predictable performance, easier inspection of the single strand, and straightforward manufacturing. The construction also provides a straightforward failure mode: with a single strand of wires, wear or damage can progress along the rope without the redundancy found in multi-strand designs.

Common applications for 1×19 rope include light to moderate lifting, control lines, and situations where a simple, low-cost rope is adequate and high flexibility is not required. For tasks demanding greater flexibility or fatigue resistance, engineers typically choose more complex constructions such as 7×19 or other multi-strand ropes.

Standards and safety considerations apply to all wire ropes. Working load limits, diameter, lubrication, inspection intervals, and replacement criteria are defined by national or international standards and manufacturer specifications. Regular inspection for broken wires, core damage, corrosion, and kinks is essential to maintain safety in use. See also wire rope, rope construction, 7×19, 7×7.
