Securall

Their website doesn’t give anywhere near enough attention to their incredible residential/​decorative stainless steel door options. I ordered five doors from them in 316 (vs 304) stainless because of a close proximity to salt water. They were able to customize things extensively, including window options, weather stripping and thresholds, handing (opening direction), frame depth and rabbet location (useful for elevator shaft openings iwth special code requirements), locking mechanisms and keying, latches, multi-​point locks for security and custom surface treatments.
Their price quote and engineering drawing approval process was very easy, but thorough, so you leave nothing to chance with regard to either unexpected expenses later, or unexpected configuration of your doors. Their excellent sales rep Jonathan kept me updated very regularly during the manufacturing phase so I always had a very good idea of when the doors would be shipping.
My doors arrived in perfect condition and I love them. The locksets are all high end commercial equipment and these doors are monsters; no chance of a burglar or your mother in law kicking them in. Might not even be able to drive a car through one.
Some additional advice; if you are receiving these types of doors for a residential project, you need to have a fork lift on site and it should have long forks; ideally eight feet or more if your order is for 8-​foot doors like mine was. A typical roofing materials fork lift that is common on a residential construction site is not sufficient because the forks are not long enough to fully support the long crates Securall ships tall doors in; you could end up dumping your doors on the street with the wrong equipment. Of course, once delivered, you’re going to need some stocky dudes to take these off the pallet and install them. An 8 foot 316 stainless door and frame weigh about 350 pounds, so these are not easy to just toss around like a traditional door.
