Err how thick is the bracket for the panel? Having bolts that can hold down an elephant is not going to help if the bracket jus shears off.
Add punched zinc steel bar on the attic side and use that to spread load by bolting to it. Beef up the bracket somehow.

Also hardened steel is stronger than stainless steel.

Those square tubes must be available locally no? Not a very exotic thing.
