Since it has been hit, run over and had several cars crash into it. It has "survived" all of it. The door was ripped off some years ago, so screws/nuts replaced the original weld on the hinge. The side and top have been dented enough several time that the door would not close. That requires some "adjusting" with a 3 lb hammer and a 16" adjustable wrench to re-straighten the metal. usually a hit of black spray paint finishes the job. I also have it bolted through the bottom with 3 x 3/8" bolts to the wooden rack (shared with about 8 other boxes). I think in the case of cars hitting it, the car does not do as well as my box.
