Understanding a Steel Cable
By Anne Ahira
There are different types of cables that have their own productive uses to help accomplish certain tasks. Ordinary cables are generally flexible and quite durable for them to be used for all sorts of occasions.
When there is a need for added durability and toughness, a steel cable could be used instead and depending on the type, the steel cable may be flexible as well just like any other cable or rope.
Also known as a wire rope, these steel cables have a long history and have evolved to be useful in many ways.
History of a Steel Cable
Steel cables had European beginnings way back in the 1600s, but they were put to use a few centuries later. Prehistoric techniques served as an inspiration to the way these steel cables are actually made.
Albert Ropes practiced on making these steel cables by hand, but had problems in the flexibility at first. The primary use during those times was to use them for hoisting to replace the unstable chains and deteriorable hemp ropes.
Through succeeding years, the construction of the steel cable changed and even patents were filed for certain techniques and strands used to make the steel cable. Steel remains as the primary material in making these cables replacing the previous material which was wrought iron.
Understanding the Current Specs of a Steel Cable
When browsing through steel cables in online retailers like Amazon.com, each item is usually listed as a title that indicates the material type and some numbers like 1×7 or 7×7. These numbers are important for the tasks that the steel cable can handle.
The first number is the number of strands used to compose the rope while the second number is the amount of wires that compose each strand. Every steel cable being sold also has a length and strength measured in pounds.
Always look at both the screenshots of the steel cable and the specifications. If the cable will be used for a very critical task, be sure to ignore all steel cables being sold that have lacking specifications. Titles that try to squeeze in all the details are good links to click first.
See if the material type is listed along with the exterior finish to determine the overall quality. Then Look at the standard construction, breaking strength, and diameter to get an idea of how tough the cable is.
If the steel cable will be used for hoisting heavy objects, the breaking strength must be greater than the weight of the object that will be lifted. Galvanized steel is a good material as it is highly resistant to rust.
Amazon is a great place to get steel cables because the price is low and shipping costs are usually free.
