<p>Method of manufacturing reinforcement steel for reinforcement of concrete structures, said reinforcement steel having an elongated shape of arbitrary length and cross-section, said method comprising the steps of: providing a steel base wire, rolling the steel base wire for modifying a cross-sectional dimension thereof and for creating a bonding profile on a surface of said wire. The method further comprises, prior to the step of rolling, the step of surface layer breaking for breaking of a surface layer and surface cleaning of said steel base wire for removing the surface layer from said steel base wire, and, subsequent to said step of rolling, applying a plurality of bending actions to the steel base wire for improving tensile properties thereof, such as to provide said reinforcement steel having a tensile strength to yield strength ratio R m /R e of at least 1,08, and having a percentage uniform elongation at maximum force A gt of at least 5,0.</p> |
