Reinforcement bars for concrete structures, comprising continuous, parallel fibers, made of basalt, carbon, glass fiber, or the like, embedded in a cured matrix, each bar being made of at least one fiber bundle comprising a number of parallel, cylindrical cross section fibers and said bars being provided with a surface shape and/or texture which contributes to good bonding with the concrete. Part of the surface of each bar being deformed prior to or during the curing by: a) strings of an elastic or inelastic, and/or b) at least one deformed section of each reinforcement bar; thereby producing a roughened surface.
