Yeah aluminium is certainly not very rigid in itself, so it's mainly the geometry of how it's arranged, the 90 degree angle with the long side perpenticular to the front/back panes. It would be easy to bend it in the other direction, towards the short side, but towards the long side it should take some pretty crazy force to accomplish. Like how you can support the weight of a small car with a bunch of eggs if you line then up vertically, exploiting their double-curve geometry. I don't have any info on what particular type of alloy of aluminum this is though.
