Domestic 9/16″ 6×37 Bright Wire Rope – EIPS IWRC

Manufactured in the USA from Extra Improved Plow Steel (EIPS), this 9/16″ bright wire rope is engineered for applications that demand exceptional flexibility and fatigue resistance. Featuring a 6×36 construction and an Independent Wire Rope Core (IWRC), this cable is designed to perform reliably in hoisting, winching, suspension, and other dynamic lifting systems where repeated bending occurs.

Colored strands may appear in some domestic wire ropes for manufacturer identification or visibility purposes. These color variations do not affect assembly break strength or overall performance.

USA-Made Flexible Wire Rope for Winching, Suspension & Dynamic Lifting

The 6×37 class is preferred for applications requiring frequent movement around sheaves, drums, and pulleys. Its 6×36 construction provides greater flexibility and improved fatigue resistance than 6×19 wire rope, helping extend service life in repetitive bending applications. While it sacrifices some abrasion resistance compared to 6×19 constructions, it excels in dynamic operating environments.

The bright finish is treated with a petroleum-based lubricant that helps reduce internal friction, minimize wear, and provide basic protection against moisture exposure.

6×37 Wire Rope Configuration

Our wire rope is manufactured using EIPS-grade steel. EIPS (Extra Improved Plow Steel) provides approximately 10% greater tensile strength than standard IPS-grade wire rope, resulting in improved breaking strength and dependable load-carrying performance.

The class of this wire rope is 6×37. These numbers nominally refer to the rope construction, consisting of six outer strands surrounding the core, with approximately 27-49 wires making up each strand. The actual construction supplied is 6×36. If you require a different construction, please contact our team.

Wire Rope by the Foot Ordering FAQ

Will my wire rope arrive as one continuous length?
Yes. The quantity you order will be supplied as one continuous, uncut length of wire rope. For example, if you order a quantity of 1,000, you will receive a single 1,000-foot length.

Can I order multiple separate lengths?
Yes. To receive multiple lengths, add each length to your cart as a separate line item. For example, if you need two 1,500-foot lengths, enter a quantity of 1,500 and add it to your cart twice. Each line item will be cut and supplied as a separate length.

Can I order lengths shorter than the minimum order quantity if the combined total exceeds the minimum?
Yes. If your combined order will exceed the minimum quantity requirement but you need shorter individual lengths, please call our team to place your order. One of our product experts will be happy to assist.
