Flat-Rolled Steel

Definition - What does Flat-Rolled Steel mean?

Flat-rolled steel refers to a type of processed metal that is generated via melting and stretching under an applied force. This force is used to create metal pieces in the form of sheets, strip or tin plates. These steels have flat surfaces allowing for easy treatment with zinc to help prevent corrosion of the substrate.

Corrosionpedia explains Flat-Rolled Steel

Flat-rolled steel is manufactured by rolling, which is performed by starting and ending with a material that has a rectangular cross-section. The metal is placed between two working rolls, moving in opposite directions. The final product is usually less than 6 mm thick. When heavy plates in the form of a press are used to mold the metal, rather than rollers, the process is referred to as forming.

The following steps are performed to produce a flat metal finished product:

  1. Reduce the material by the same percentage across its width
  2. Preserve uniform mass flow of the metal during processing
  3. Use corrosion preventative initiatives during processing

The corrosion of rolled steel requires an electrolyte to be in contact with its surface.
