They're aluminum (although the rack itself is tubular chromoly), and Tubus stresses that they should be installed in such a way that there is no strain or bending force on them.
Here's mine with straight (and too long) struts:
I didn't want to cut the struts in case I ever want to put it on some other bike that needs longer struts. It'd look better with them shortened, but it doesn't harm anything to have them a bit long. Mine just happen to go to the eyelets without any strain, so I don't need to bend them.
