A billet for production of hot-rolled sheets has a rectangular form of cross section, and protrusions and depressions alternating with a constant step on the wide faces. For the purpose of improvement of the flatness of finished rolled metal due to averting of accumulation of inequality of deformations lengthwise and along width on the motion of rolling, protrusions of both faces are inclined at equal angles toward the longitudinal axis of billet. The protrusions of one face are expanded relative to opposite protrusions on another face in opposite direction, and their axes are crossed.
