I disagree with you on that one. The plywood sheets aren't carrying the full load above them. You can't see this easily because the labels are in the way, but each pallet has another vertical support running down the middle of it. So it looks as if there are only about 12 inches between each support -- which means these pallets are not the typical industrial pallets you see in a warehouse.
I agree with you. From what I'm seeing, these pallets are only maybe 24" squares. It looks like the pallet supports are maybe 2 x 6's. Most everyday pallets are nominally 1 x 4's.
