Dear Pianoexpert, I noticed that on some upright piano models the company Grotrian-Steinweg installs strings with polygonal cross-sections; is there a valid reason behind this type of choice?

THANK YOU in advance

The steel of the bass strings may not have a round cross-section. According to some, this favors the adhesion of the copper.
