Correct. Most of their frame models were aluminum, during their collaboration with Cinelli. I have their Parallax from about 2015, and it's Columbus 7075. Other models might have been different alloys. The Work was steel.
Not sure if they're still making (or sourcing) their own frames now, independent from Cinelli. Maybe they now have a model just called MASH that is steel; if so, I'm not familiar with it.
