I can't say for sure yet... My first serious trail ride will probably come next week.
Not to get all geology 101... but, I would say that it has a lot to do with the type of rock. Most igneous rocks will tear the heck out of anything. Sedimentary rocks will tend to crumble and maybe cause some abrasion.
I don't know for sure what type of aluminum was used... but there is a big span in terms of strength of aluminum alloy; MPa 200 to MPa 600. It looks to be pretty strong stuff; A friend who helped with the install joked that we were going to have an Isreali armored personnel carrier by the time we were done (ASFIR is an Isreali company).

How are those aluminum skids for sliding on rock? Some folks with aluminum canoes, for instance, find that the aluminum bites the rock and sticks. Or I guess, the rock bites the aluminum. Anyhow, that could make a difference with rock crawling if you get hung up a little.
