To answer your question “How do they do it?”, they first roll a plate into a cylinder and ‘weld’ the joint (without filler metal) and then proceed to roll the cylinder into a square or rectangular profile.
I'm a little behind in my Digests, but...
Someone correct me if I'm wrong, but I thought HSS sections have a stated range of radius (measured at the outside of corner) or 2T to 3T. I thought they usually ran closer to 2T, which means an inside radius of 1.0T and a mid-thickness radius of 1.5T.
How do they do it? They're bent cold. Gradually (several progressive steps), but cold.
