I'm working on the setup for a 100% Brett open fermentation and want to use steel or glass as a fermentation very with a very low aspect ratio (height:diameter < 1) to maximize the open character.
Originally I came across a few 2" deep steel heated food trays at Sam's Club but looking into it further the steam trays that go underneath those are sold at up to 6" deep which should roughly fit 6 gallons (Amazon reviews say ~5G though). These are made from 22-24 gauge steel and they're easy to clean.
My plan is to get the tray and possibly drill a hole for a bottling bucket spigot to easily transfer the beer. An autosiphon might work just as well.
To keep the fermentation sanitary there are plenty of furnace air filters which fit the 13"x21" profile and can be taped over the top of the tray. I ordered the lid too but I feel like it might inhibit CO2/O2 flow. I'd like to play around with putting a fan with a filter above the tray to remove CO2 faster and allow more O2 at the surface.
This gets an aspect ratio (height to sqrt(area)) of 0.4 when filled to 6" deep.
NOTE/EDIT: Now that I thought about it that spigot should be centered at the bottom of the narrowest side.
