The ribbed round is a steel element used in the reinforcement of reinforced concrete structures. This type of element is characterized by a circular section with a grooved or corrugated external surface, in order to increase the adhesion between the steel and the concrete. Thanks to the ribs, the ribbed rod allows greater ductility and resistance of the element in case of stress. Furthermore, the grooved surface favors the transfer of stresses between steel and concrete, thus ensuring greater stability and safety of the structure.
