cut through those thin steel angles in the pict quickly, yes. battery powered angle grinder or torch.
cut through concrete wall? yes. quickly? not a chance
no obstacle is absolute
but there has to be a certain standard
plain steel slats, pipes, etc are a scam. too easy to get through in any practical thickness
scrappers will come out at night and tear them down just for the scrap money
anyone willing to carry this ball any further?

like I said
steel is a slide
except maybe in a few select locations, CONCRETE with rebar is what needs to be done
