Offsquare. The most extensively used sequence for rolling squares is the one shown in Fig. 7.25. This sequence consists of a finishing square, leader diamond and strand square passes. The bar obtained in the breakdown passes will enter into the strand square pass. Then the bar is turned 90 and entered into the leader diamond pass.
