Types of 6mm Steel Wire Rope
Steel wire ropes come in various constructions and materials, each suited for different applications. The most common types include 6×36, 7×19, and 1×19 constructions, which offer distinct advantages depending on the specific needs of your project.
6mm 7×19 Stainless Steel Wire Rope
One of the most common types of 6mm steel wire rope is the 7×19 construction. This rope has 7 strands, each containing 19 wires, providing high flexibility and fatigue resistance. It is commonly used for hoists, winches, and applications that require continuous load running. This type is particularly popular in the marine and construction industries, thanks to its corrosion-resistant properties when made from stainless steel (AISI 316), ideal for harsh environments.
6mm 7×19 Galvanised Steel Wire Rope
The 7×19 construction is also available in galvanised steel, which offers similar benefits in terms of flexibility and fatigue resistance. However, galvanised steel provides additional protection against corrosion, making it suitable for outdoor and marine environments. This wire rope is ideal for lifting, rigging, and general applications in construction.
6mm 6×36 IWRC Galvanised Steel Wire Rope
The 6×36 construction is designed for heavy-duty applications that require high strength and durability. This type of wire rope has 6 strands, each made up of 36 wires, which offers excellent flexibility while maintaining superior breaking loads compared to the 6×19 construction. The 6×36 construction with an independent wire rope core (IWRC) is commonly used in engineering and heavy lifting.
6mm 1×19 ProRig AISI 316
For applications requiring high tensile strength and durability, the 1×19 ProRig AISI 316 is an excellent option. This type has a single strand made up of 19 wires, making it less flexible but more suitable for high-strength applications such as architectural uses, tensioned cables, and certain rigging applications.
6mm 3 Core SWA Armoured Cable
While not a traditional steel wire rope, the 6mm 3 Core Steel Wire Armoured (SWA) Cable provides protection for electrical wiring, making it a popular choice for construction and outdoor applications. The armoured core protects the cables from mechanical damage, offering high durability in harsh environments.
Applications of 6mm Steel Wire Rope
Steel wire ropes, particularly 6mm versions, are highly versatile and are used in a range of industries. Here are some of the most common applications:
Construction and Rigging
In construction, 6mm steel wire rope is used for a variety of tasks, including lifting heavy loads, rigging, and supporting structures. The 7×19 and 6×36 constructions, in particular, are widely used due to their flexibility and high tensile strength. Steel wire ropes are often employed in cranes, hoists, and other lifting equipment.
Marine Applications
The 6mm stainless steel wire rope, particularly the 7×19 construction, is widely used in marine environments. Its resistance to corrosion makes it ideal for applications such as ship rigging, mooring lines, and other marine-specific tasks. It also offers the flexibility required for continuous load running.
Electrical and Telecommunications
The 6mm SWA (Steel Wire Armoured) cable is frequently used in electrical and telecommunications applications. The armoured layer protects the cable from external damage, ensuring reliable performance in outdoor or high-risk areas where exposure to mechanical damage is possible.
General Engineering
The 6mm 6×36 IWRC wire rope is commonly used in general engineering applications, such as winches, pulleys, and tensioned cables. The superior breaking load and flexibility of this rope make it suitable for handling heavy-duty tasks with ease.
Agricultural and Industrial Applications
In industries like agriculture, 6mm steel wire ropes are used in equipment such as conveyors, mechanical links, and tensioning devices. Their durability and flexibility ensure that they perform well in tough industrial conditions.

Choosing the Right 6mm Steel Wire Rope
When selecting the appropriate 6mm steel wire rope for your project, several factors need to be considered:
1. Material
The material of the wire rope determines its durability and resistance to corrosion. Stainless steel is ideal for marine or highly corrosive environments, while galvanised steel provides protection against corrosion at a lower cost.
2. Flexibility
The flexibility of the wire rope is crucial for applications involving bending or twisting. For example, the 7×19 construction is more flexible, making it ideal for hoists and winches, while the 1×19 construction is more rigid and better suited for high-tensile applications.
3. Tensile Strength
Different types of wire ropes offer varying tensile strengths. The 6×36 IWRC construction is known for its high breaking load, making it ideal for heavy-duty applications that require maximum strength.
4. Core Type
The core of the wire rope plays a significant role in its strength and flexibility. Fibre cores (FC) offer flexibility, while independent wire rope cores (IWRC) provide additional strength and support for heavy-duty tasks.
