Calling it structural doesn't make it structural.

1/8 aluminum is pretty thin, and I doubt you'll actually be relying on it for any structural support for the robot - especially not in a single thin strip.

Definitely Q&A this, because as I see it, if you had a judge that understands robot design, they'd take one look at that 1/8 inch thick strip of aluminum and tell you it doesn't meet the rule.
