We have one powder coated chassis for the competition robot, and another complete un-powder coated chassis for a practice robot, as well as a handful of additional backup parts. (It was actually more economical for our sponsor to punch out two complete CNC sheet metal chassis' for us and use a complete sheet 4'x8' sheet of 0.125" aluminum, rather than use only half of one to make a single chassis and have to store the rest in his shop until another client would need it.)
