Suspended Ceiling and Duct Conflict

It's not an issue to attach hangers to the duct then?

I wouldn't think so, you're not tying up the Queen Mary, lol. Pull down on the duct and see how it feels, as long as the duct is secure, and if in doubt throw another strap around the duct somewhere, and it should be fine.

Well, if the tin won't just fold up on me

Cut a piece and see what it feels like. You will still have a bit of the upright piece left....yes?
