[AT] OT...Need some advice on old metal building

How about a nut cracker? Those normally do not operate fast, but they do remove square or hex nuts from just one side of an installation.  You may be able to rig up a power drill to do the heavy work for you.  I think I bought a set of them at Harbor Freight.  They come in two sizes, and I used mine about a month ago to split a rusted square nut on an antique cultivator that I'm restoring.  the across flats distance was one inch.  That was the absolute limit of the nut cracker, but it did it without any broken tools or busted knuckles.

Have you tried tightening them instead? That will probably snap them off.
Not sure if that's what you're looking for but...

We put a hopper bin together with a dome shaped slotted screw with square
nuts and we could break those silly things with hand tools. Where the head
attached to the screwed part was soft, weak or whatever and would just pop
off if you reefed on it with a large screwdriver, let alone an open end
wrench. Made air tools useless since we couldn't set the torque low enough.
A butterfly wrench might work now but Dad didn't have one back in the day.
