Cold-finished steel is essentially hot-rolled steel that has undergone further processing. Cold finished steel, also known as cold rolled steel, is typically produced as turned bars or cold drawn bars. Cold drawing hot-rolled bars is accomplished by pulling (drawing) a bar through a die that is smaller than the incoming hot-rolled size. The cold working process improves the dimensional tolerances of the bar, the straightness, and the surface appearance, as well as enhancing the physical properties of the steel. Eaton Steel Bar Company, via our sister company Hercules Cold Drawn Steel, is able to provide ¾" through 9" rough turned and turned and polished.
Cold Finished Bar Capabilities
Eaton Steel Bar Company provides turned rounds and cold-drawn rounds, squares, and hexagons in sizes ranging from 1/4” through 9”. With over 10,000 climate-controlled racks in our Taylor Distribution Center, we are able to supply quality products just-in-time to your door.
Cold Finished Steel Bar Benefits
There are several benefits to using cold-finished steel bars. Some of these benefits include:
| Size & Roundness | Cold-rolled steel has tighter size and roundness tolerances. |
| Straightness | The straightness is more precise than hot-rolled steel. |
| Surface Finish | Cold-finished steel is smooth and can be used for a variety of applications. |
| Mechanical Properties | The need for heat treatments is often eliminated due to the increased yields and tensile strength of cold-finished steel. |
| Machinability | When using lower carbon grades, the machinability is improved, which leads to a better tool life. |
Turning hot-rolled bars is a cold machining process, which removes the surface of the hot-rolled bars, improving their dimensional control while removing superficial features of the hot-rolled bars that may be detrimental to the surface of the parts produced.

Cold Rolled Steel Bar Applications
While most industries, like construction, utilize cold-rolled steel. There are common applications for this steel, such as:
- Gears and shafts
- Oil and water well shafting
- Industrial buildings
- Products that demand a defect-free surface
Cold-rolled Steel Bar Process
All Eaton Steel cold-drawn bars are also produced with our proprietary surface inspection equipment.
Eddy current, roto–bar testing, or mag testing are all available and used as required. The modification of the ultimate tensile strength, the yield strength, and the elongation of the bars assists in improving machinability and chip formation.
Cold-rolled steel bars are commonly classified in the following ASTM specifications:
- ASTM A 29
- ASTM A 108
All Eaton Steel cold-drawn bars meet the following specifications:
- AISI
- SAE
- JIS
- DIN
