We always routed the raw materials directly from the steel mills to our sub’s plant they did the rough cutting and bending, etc. Some of these subs are better at handling one type of shape than another.

This type of bending work is quite a specialty in terms of the needed equipment, knowledge and experience, and what they can actually achieve with a given shape and size, without bending/buckling the hell out of the whole section. You will also see ads for this type of work in various structural steel mags.

Ask them who they would job this bending work out to (sub this bending out to), and then talk with those people who specialize in this large structural shape and HSS bending. I would talk with several structural steel fabricators who you have worked with in the past or who might be involved in this project.
