Realization of “closed-loop” stirrups, with no joints, allows to produce a real “confinement”, highly efficient.
Moreover, in the case of poles, the ring ( Stirrup ) is produced with a polygonal geometry in order to easily accommodate the reinforcing bars at each corner, therefore the figure will have so many “corners” as the number of bars designed for the cage; it all means a large facilitation for the assembly of the cages.
