Metal: not really. Wooden beams? Yes, there are beams, in varying states of decay. You can find a dozen or so that are serviceable around the town in the older buildings (or more if you want to take apart the other buildings, like the saloon or store, both wood buildings--there's also metal in the diner if you want to take that apart, that classic diner corrugated metal. We're not the cops, no one's gonna stop you).
