What does rolling and forming do to metal stock?

• A. It completes heat treatment to condition metal
• B. It coats metal with zinc
• C. It removes surface oxides
• D. It passes metal through rolls to transform a billet into any shape

Answer: (D)

Rolling and forming reshape metal by plastically deforming it as it passes through rollers or dies to create new shapes. The metal isn’t melted; the forces change its geometry, turning a billet into longer sections with specific cross-sections and profiles—such as bars, channels, angles, tubes, or other forms—depending on the tooling. This is a forming operation that builds shape, not a heat treatment, coating, or surface-cleaning process.
