Some of the objects here serve no purpose other than to be mediocre cover and a minor obstacle, but others can be attacked for steel slag chunks, and a few have a potential unique use (e.g. using the lamp as a (very) weak light supply).
I would suggest that we add two extra columns - one to indicate how much scrap it gives when broken, and one to indicate any useful properties of the object (if it gives light, if it contains anything useful, if it's exceptionally good cover, etc.)
I'd do it myself but I'm nowhere near familiar enough with wiki formatting to trust myself to not completely bork the table by adding new columns.
