1. Cutting / Shearing of Rebars
The Bars with improper ends like bent, too much heated, improper manufactured ends etc., are cut with Band saw machine. This is done in order to achieve a approximate Flat face for further forging of the Rebar.

3. Threading of Rebars
The Forged end of the bar are then threaded with a threading machine, the machine consists of 4 chasers, which generate the needed thread profile on the bar end. The threads are then checked with a GO Gauge & NO-GO Gauge. Depending on site conditions, the threaded ends are stored for further site installation.
