Unfortunately, no they do not. We have two different punches for each shape, one that punches a smaller sized shape, then another that flanges the edges of that shape out.
All the pieces do have folds in them though.
Here is a photo of one of our practice bot siderails being made.
Here is a closeup of that siderail. After the first successful rail, we switched to an impact wrench to make things go faster.
Also, our bearings holes are punched in the same way. It's really neat, come take a close look at our robot sometime.
