FIELD: construction.
SUBSTANCE: method involves twisting a reinforcing bar around its longitudinal axis. The reduction rolling of a reinforcement workpiece round or square in the cross-section at a temperature below the recrystallization temperature in a square gauge with a deformation degree of 20-40% and its subsequent twisting to ensure the formation of a reinforcing bar with a screw profile on its surface with an inclination angle of 35-60° to the longitudinal bar axis are performed successively and continuously.
EFFECT: increasing the strength of reinforcing bars.
