A wire rod is primarily made by Rolling. Rolling squeezes metal between rotating rolls to reduce thickness and set a profile, hot for heavy reduction or cold for finish and strength. Below is the full route to make a wire rod, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.

Step by step

How a wire rod is made

The usual route, raw material to finished part. The amber step is where the wire rod gets its basic shape.

  1. Feedstock

    Start from cast billet, bloom or slab.
  2. Rolling

    Form the wire rod as a continuous profile or stock and cut it to length.
    Tooling Very high (mill)   Tolerance ±0.1 to 0.5mm   Lead n/a (stock)
  3. Cut to size

    Saw or shear the stock to the lengths you need.
  4. Secondary work

    Machine, drill or bend wherever the raw section is not yet final.
    Tooling None   Tolerance ±0.125mm, to ±0.025mm   Lead 1 to 10 days
  5. Finish

    Deburr and, for aluminium, anodise; otherwise plate or coat.
    Tooling Low   Tolerance adds microns   Lead days
  6. Inspection

    Verify section, straightness and length.

  • Non-standard gauge. Design to standard sheet gauges.
  • Grain direction ignored on bends. Orient bends across grain.

What a wire rod should cost

Rolling makes sheet, plate, bar and structural shapes; bought as stock by weight or length, not tooled per part.
