What is 1×19 Steel Strand?
A 1×19 steel strand is a high-performance cable constructed from nineteen individual steel wires twisted together into a single, highly compact strand. Compared to the more rigid 1×7 construction, the use of a greater number of finer wires gives the 1×19 strand two distinct advantages: enhanced flexibility and a smoother, more uniform surface finish.
This improved flexibility allows the strand to be bent into gentle curves without compromising its structural integrity, making it perfectly suited for applications like architectural railings that must follow a staircase or balcony. The smooth surface not only provides a modern, aesthetic appeal but also reduces abrasion on connecting fittings, making it the industry standard for standing rigging on sailboats and other demanding applications where both strength and a refined appearance are paramount.
Features & Benefits of 1×19 Steel Strand
Enhanced Flexibility
The 19-wire construction offers greater flexibility than 1×7, allowing it to easily conform to gradual curves for railings and rigging.
Ultimate Corrosion Resistance
Available in stainless steel and hot-dip galvanized options, ensuring maximum longevity in the harshest marine or outdoor environments.
Smooth & Aesthetic Finish
A compact, uniform surface provides a modern, high-end look, making it the premier choice for architectural and marine applications.
High Strength & Reliability
Despite its flexibility, our 1×19 strand maintains exceptional tensile strength and low stretch, ensuring reliable support for critical loads.
Common Applications of 1×19 Steel Strand
Architectural Railing Systems
As the premier choice for modern cable railings on staircases, decks, and balconies, its sleek appearance and ability to follow contours provide an unobstructed, minimalist aesthetic.
Marine Standing Rigging
Used extensively on sailboats and yachts for standing rigging (shrouds and stays), where its high strength, low stretch, and superior corrosion resistance (especially in stainless steel) are critical for safety and performance.
Structural & Decorative Supports
Ideal for tensioned support systems in canopies, green walls, and architectural façades where a more refined and less industrial appearance is desired.
Industrial & Automotive Controls
Utilized as control cables, push-pull cables, and throttle cables in various machinery and automotive applications where a smooth, low-friction surface is required.
Quality Assurance & Standards
Quality is the foundation of every product we manufacture. Our 1×19 steel strand is produced in facilities that adhere to stringent international standards such as ASTM, ISO, and EN.
From raw material verification to final breaking load tests, our dedicated quality control team monitors every stage of the production process. This rigorous oversight ensures that every strand meets its specified requirements for performance, consistency, and safety.
We provide full material traceability, and Mill Test Certificates (MTCs) are available upon request, giving you complete, documented confidence in the product you receive.
