Wire ropes and cables are used for a variety of applications. You may require rigging for shade sails, balustrades, or other structural or architectural needs. Finding the right product increases safety and helps prevent accidents and injuries. You should know what features and details to consider when selecting the best stainless steel wire ropes.

Pay Attention to the Stainless Steel Grade

Stainless steel ropes are graded based on the makeup of the materials used for construction. This includes 302, 304, 305, 316, and 321 stainless steel. Each grade has its own advantages and is intended for different applications. The 300 series is made with austenitic chromium-nickel alloys and is generally used for its corrosion resistance.

The 304 grade is the most common choice for general applications. However, 316 stainless steel wire rope provides better corrosion resistance. It includes molybdenum to prevent additional forms of corrosion, including chloride corrosion. These benefits make 316 steel wire more suitable for marine rigging.

Consider Flexibility and Cable Construction 

The next detail to consider is the flexibility of the wire rope configuration. The cable construction refers to the number of wires in a strand. More wires provide more flexibility and stretching ability. The standard cable construction configurations include 1×19, 7×19, and 7×7 construction.

The 1×19 configuration means that there are 19 wires in a strand. While this construction provides less flexibility, it offers more strength and resistance to compressive forces. If the rigging does not need to flex or stretch, this is one of the sturdiest options available.

The 7×19 construction includes 7 strands, with each strand containing 19 wires. This cable provides the most flexibility and stretch. It is sturdier than the 7×7 construction and recommended for applications that require the use of pulleys.

The 7×7 configuration is a general solution that falls somewhere between the other two options in terms of durability and flexibility.

Determine the Maximum Load for Your Application

Before you can choose the right wire rope, you need to determine the maximum load that you may apply to the rope. The maximum load is compared to the strength of the rope to determine the safety factor. If you have a wire rope with a strength of 20,000 pounds and a working load of 5,000 pounds, the safety factor is four to one. In most settings, you will want a safety factor of at least five to one.

These are a few of the main considerations for choosing the best stainless steel wire. You should also discuss your intended application with the supplier to ensure that the wire rope you choose meets the demands of your environment. They can help you find the right strength, construction, and grading for your stainless steel wire. The right choice will help keep you and your employees safe.
