A wire rod is a hot rolled wire, which can have a diameter of anywhere from 5.5 to 42mm. A standard quality rod can be made of various materials such as carbon steel, stainless steel, aluminium, and ordinary quality copper. However, stainless steel wire rods offer unparalleled quality with high corrosion resistance and high weldability. Depending upon the technical parameters of the material type, the cross-section of wire rods can be hexagonal, round or square. But the majority production of wire rods is in round cross-section in nominal diameters of 5mm to 19mm.

Manufacturing of Wire Rods

  1. Wire rods are manufactured by hot rolling billets on continuous rolling mills.
  2. It is extracted from hot metal through shafts.
  3. The shafts shape and compress the metal from various sides, transforming a piece of metal into a thin, long cable.
  4. The rod needs to be cooled after rolling.
  5. This wire is wound on a special winder at the end of the rolling mill for the further cooling process.
  6. There are two ways this process can go: by air or rapid cooling.
  7. Unlike rapid air cooling, which involves special fans, air cooling happens naturally.
  8. The rod is ready for storage after cooling.
