This type of product is quite common and can be used in a wide variety of industries, as well as other spheres. Naturally, the main applications for wire rod are manufacturing, the energy sector, and construction.

Wire Rod Manufacturing

Wire rod is a hot-rolled wire with a diameter ranging from 5.5 to 42 mm. Rods are made of carbon steel, aluminum, and copper of ordinary quality. The cross-section of wire rod can be hexagonal, round, semicircular, or square. The main factor that determines the technical parameters is the type of material it is made of.

Wire rod is made by drawing hot metal through shafts. The shafts form and compress the metal from different sides, thus turning a piece of metal into a long, thin wire. At the end of the rolling mill, this wire is wound on a special winder, with the help of which the rod is rolled into skeins for further cooling. The production method is called ‘hot;’ however, the metal is not pre-heated – it is heated when passing through the shafts.

After rolling, the rod must be cooled. This process can go in two ways: through air or accelerated cooling. Air cooling occurs naturally in contrast to accelerated, which requires special fans. After cooling, the rod is ready for storing.

High-quality requirements are imposed on wire rod. For instance, if the rod is manufactured for further wire production, then it should be free of burrs or other deformations. If they are present, the rod can still be used for other purposes.

Apart from that, voids and bubbles may appear on the surface of the rod, significantly reducing the strength of the material. The quality of the product is also adversely affected by decarburization, which may occur when the rod is heated.

There are other mechanical defects that may occur; some of them only affect wire rod prices, while others make it unusable. Therefore, production is controlled carefully, and the rod goes through constant quality control at all stages of manufacturing.

Usage of Wire Rods

There is a variety of applications for steel wire rod, such as:

  • Aviation
  • Engineering
  • Reinforcing concrete structures

For example, in the manufacture of reinforcement cages; square, round, or rectangular-shaped assembly clamps are made from wire rod. With the help of reinforcing cages, monolithic columns, girders, belts, cross-tops, and lintel strip foundations are reinforced.

In addition to the use of wire rod in reinforcing cages, it is also used in the manufacture of welded reinforcing mesh for monolithic structures, such as concrete floors and screeds.

Steel rods are also used when laying bearing walls or walls of brick, cinder, foam, or gas block. Depending on the concrete used for masonry, steel wire is put into each 2nd-4th layer of mortar, thereby enhancing the overall strength of the masonry. Thus, the rod performs the role of reinforcing the structure.

Apart from that, wire rod is used in the production of electrodes and wires for welding, as well as the manufacture of telegraph wires, ropes, and cables. For such applications, aluminum and copper rod fits best. Most often, such wire is used in power supply systems. In order for rod not to affect the operation of these systems, it must be plastic and well deformable. These characteristics play a key role when choosing the right diameter of the rod.

What is Steel Wire Rod?

For more coiled wire rodinformation, please contact us. We will provide professional answers.

Wire rod is a rolled steel product (alloy or non-alloy), manufactured from semi-finished steel with a rectangular, rounded, hexagonal or squared shape. Especially, fine cross-sections are reached by sequent cold drawing. Wire rod is wrapped around into the coils and also carried in this form.

Steel Wire Rod Hs Code: 7213 (Steel Wire Rod, Steel Wire Rod Coil)

Wire Rod Usage

Steel wire rods can be used for a wide range of products depending on how it is shaped and treated. The main usage is in the manufacturing of:

  1. wire mesh,
  2. nails
  3. springs
  4. reinforcement wire
  5. barbed wire
  6. wire ropes
  7. welded wire mesh.

Wire Rod Shape and Size

The steel wire rod is a finished product and is cold-formed for farther processing. Although it has a variety of shapes, it is mostly rolled round. Diameters often range from 5 to 15 millimeters, with most comply with the ISO standards, makes it easy for the sizes to advance in increments of 1 mm to 20 mm.

All steel wire rods are formed into the coils without any break. This is to ensure that steel wire rods are well-prepared for farther processing (usually by heat treating, coating, and cleaning). The coils’ internal diameter often varies from 810 to 910 millimeters, and the external, from 1100 to 1300 millimeters (depends on the capability of mill’s equipment). Subsequently, the weight of the coils differs from approximately 600 kg and larger above 2 tons.

Wire Rod Properties and grades

According to the type of material, Steel wire rods are manufactured in different grades.

Carbon steel wire rod is the most common with no minimum content specified or required of molybdenum (Mo), aluminum (Al), chromium (Cr), niobium (Nb), cobalt (Co), nickel (Ni), tungsten (W), titanium (Ti), zirconium (Zr), vanadium (V), or any other element required for a particular effect of alloying. Carbon steel wire rods contain copper content, generally up to 0.40%. Moreover, the manganese content will not exceed the level of 1.65% and 0.60% will be the maximum level of silicon.

These steel wire rods are supplied in the following grades:

  1. Low Carbon:

    • with C content ≤ 0.15 %. This is also known for “mild steel” or “electrode steel”.
  1. Medium Carbon:

    • Low grade; includes 0.15% < carbon content ≤ 0.23%
    • High grades; includes 0.23% < carbon content ≤ 0.44%.
  1. High Carbon:

    • includes C content > 0.44 %.

Besides the grades, there are other features to be guaranteed for carbon steel wire rods while going through the various processes to be with no defects as well as have the right performance according to the destined application.
