Steel Wires: Types, Applications, Benefits and More

Steel is known to be an important raw material for various industries. We have already explored various steel products such as steel plates, TMT bars, aluminium coils, and so on. Just like aluminium coils, steel wire is a versatile product and has varied applications. This article will explain, what steel wire is, how steel wire is made, its benefits and applications.

What is Steel Wire?

Steel wire is a flexible, cylindrical strand made of steel. It is used for various applications, however, one of its important uses include lifting heavy materials in construction, logistics, infrastructure industries. Its manufacturing process generally involves several steps such as rolling, surface heating, etc.

How is Steel Wire Made?

Step 1: Generally, the raw material for making steel wires include steel rods which are supplied by integrated or mini steel plants. Steel rods are often made from billets using a hot rolling process.

Step 2: Surface treatment is the next step. Descaling and surfacing coating are done, which further enables the drawing process.

Step 3: The third step of making steel wire is drawing. The rod is brought to the drawing machine and the required diameter wire is drawn.

Step 4: Then, the drawn wire undergoes the patenting process. Patenting is a type of heat treatment wherein the wire is heated at about 900°C and then quenched into molten lead at 500°C.

Step 5: Intermediate drawing takes place.

Step 6: The last step is stranding and closing. Wire and strands positioning are confirmed and closed.

Note: The process of making steel wires may vary depending on a manufacturer

Various companies produce steel wires. Global Wires Business (GWB), a division of Tata Steel, is one of the largest steel wire manufacturers in the world.

Benefits of Steel Wires/Ropes

Steel wire ropes are one of the important components for many industries. Here are some of the benefits of steel wires.

• Corrosion resistance: Steel wires can withstand harsh weather conditions, hence corrosion is less likely. Sometimes, steel corrosion can take place under certain conditions however, it can be avoided with timely maintenance.
• Tensile strength: Steel wire showcase excellent tensile strength, which makes them an ideal choice for use in infrastructure construction.
• Ductility: Many metals deform under tensile strength however, steel wires do not. This makes steel wires an ideal choice for use in electrical cables, etc.

Types of Steel Wires

Depending on the raw material used, the manufacturing process and its usage, there are many types of steel wire available in the market. Some of the popular types of steel wires are listed below:

Stainless steel wire: Stainless steel properties makes it a robust material that does not corrode quickly. Hence, stainless steel wire ropes are ideal for the use where it may come in contact with water and humidity. It is best suited for industries such as marine, architecture, etc.

Galvanised steel wire ropes:  Galvaised wire ropes are coated with molten zinc. As a result, galvanised steel wire ropes display the features such as high strength, corrosion resistance, etc. Therefore, these wire ropes are ideal for general engineering purposes.

Carbon steel wire ropes: There are low and high carbon content steel wire ropes. While carbon adds strength to it compromises flexibility. Hence, low carbon steel wire ropes are used where more flexibility is required. On the other hand, high carbon steel wire ropes are used where the focus is more on strength and not on flexibility.

Coated steel wire ropes: Coated wire ropes are generally coated or jacketed with materials such as polypropylene, PVC, nylon, etc. Such coating offers protection to the steel wire against wear and tear and also corrosion.

Apart from the four types mentioned above, there are various other types of steel wire ropes. Steel wire ropes come in different sizes, such as 3mm, 6mm, 9mm and so on. Additionally, custom made steel wires are made of different types of steel and coating also differs as per the application.

Maintenance and Safety Tips for Steel Wires 

Steel wire ropes work under high stress and must be maintained carefully to ensure safety and long service life. Regular inspection and timely upkeep reduce the risk of accidents, equipment failure, and costly downtime. 

Routine Inspection

Check wire ropes before each major operation and carry out a full inspection at least once every three months. Look for broken strands, rust, kinks, corrosion, or any visible damage along the rope’s length. Replace any rope that shows significant wear or reduction in diameter. 

Lubrication

Apply suitable wire rope lubricants at regular intervals to minimise friction between strands. Lubrication also prevents rust and corrosion, especially in humid or coastal environments. Use wire-specific lubricants rather than general oils or grease. 

Cleaning 

Remove dirt, old grease, and salt deposits using a wire brush or approved cleaning agents before applying new lubricant. Clean ropes perform better and last longer. 

Storage

Store wire ropes in a dry, shaded area away from direct sunlight, moisture, or chemicals. If stored for a long time, inspect and re-lubricate them periodically to maintain flexibility. 

Handling and Operation

Always use proper lifting and winding techniques. Avoid dragging wire ropes on rough surfaces, as this can cause abrasion and internal damage. Use sheaves and drums of the correct size to prevent over-bending. 

Replacement Intervals 

Replace ropes immediately if more than 10% of outer wires are broken in any strand length, or if corrosion or crushing is detected. In heavy-use industries such as mining or construction, replacement may be required every 6–12 months depending on load cycles. 

Record Keeping

Maintain a logbook of inspections, maintenance actions, and replacements. This helps track rope conditions and ensures compliance with safety standards.
