Joining Hylight

I want to do a project with the material Hylight (a composite of aluminium and PP). I am looking for a way joining this material to a carier. I don’t prefer a clue due to the man-dependent strenght of the joint. A srew or nail would be vissible. Is there any other way thats not visible and is not man-dependent?

why dont you ask the guys who make it…they would know best
