ABSTRACT:
The threaded deformed reinforcing bar is used in concrete construction and may be easily connected to other threaded deformed reinforcing bars by an internally threaded coupler. The threaded deformed reinforcing bar has a continuous spiral thread upon at least a portion of its length which engages the internally threaded coupler. The continuous spiral thread upon the deformed reinforcing bar is formed by eliminating portions of longitudinal ribs that are formed upon the reinforcing bar during manufacturing. This process for forming the threaded deformed reinforcing bar is less expensive than conventional processes.
