Since it's only 1.25" aluminum, I'm more concerned with compromising the structural intergrety by drilling 12 holes in each 33" piece - or 24 if we use bolts.

>the point it will fail is when someone accidentally steps on it.
Doesn't matter. The downward force is applied to the aluminum which is seated in the 2X6, so no harm, no foul.

We went with #10 self tapping screws and nuts and bolts in the front (pops being controlling and making everything into an all day project. Still love him tho)
A little putty and paint and it'll look fine. My calculations are the aluminum should hold 2,500 lbs total. With holes, the limit is 3/4 of that. For safety sake, cut that by 1/3. So we still have a weight limit of 550lbs. Unless you're moving a fridge or have a couch on top, it came out alright.
