Abstract

Barra de acero, por ejemplo, barra de armadura de hormigón, barra tensora o similares, con nervios, producidos mediante un proceso de laminado en caliente, dispuestos simétricamente con respecto a su eje longitudinal, que siguen una línea helicoidal y forman partes de una rosca, caracterizada porque se han previsto más de dos nervios, preferentemente cuatro distribuidos uniformemente sobre la periferia de la barra.
