Received 05/02/2021.  Specifically ordered these because all the Q&A and description said several times that the frames were rust resistant aluminum.  When the box arrived, it seemed very heavy for aluminum chairs.  Took the chair pieces out and put a magnet to the legs and chair frame, and the magnet stuck.  Ended up returning chairs as I did not want steel staining my patio and  steel frames are usually much less expensive than aluminum, and these chairs are priced as if they were aluminum.
