[origin: EP0244758A2] The invention refers to a deformed steel bar (32, 33, 40, 50) for concrete constructions. To improve the adhesion between the steel bar and the concrete the steel bar has a longitudinal sectional profile which varies alternately and smoothly with a peak (a1, 3A, 51) and a valley (a2, 52) in the axial direction thereof.
