Abstract

In order to make a concrete reinforcing rod (1), exhibiting a characteristic ribbed arrangement for identification of the steel quality or origin, suitable for a threaded connection, mutually parallel oblique ribs (2, 3) are arranged on both circumferential halves along a helix and ribs (4, 5) lying outside this helix are reduced in height to such an extent that they do not hinder the screwing-on of the associated anchoring or connecting member. <IMAGE>
