Any chance of having a thread listing stainless steel suppliers? I know there is already one for steel suppliers but thought it may be helpful and save a bit of time having the stainless list separate.
You may find that a good number of the ones listed as fabricators rather than large stockholders will have small amounts of non ferrous. Some listed will also deal in both.
Avon Steel, being one that does both, that I would think covers your area.
Might be worth finding you local ones in the list, then giving them a buzz.
Not that many suppliers around who supply non ferrous/stainless metals only I find.
We use Richard Austin alloys or Aalco who have branches all over the UK. Richard Austins are the better of the two IMO.
