The Numenorians actually also had a technological revolution, although I don't know whether it was industrial. They unfortunately faced the setback of being almost entirely wiped out when their continent was sunk by Illuvatar.
Both the Elvish and Numenorian comments discussed hand-made, almost magical creations similar to what we imagine pre-industrial. So I think we're all in agreement that there were some amazing things created, but not at scale (perhaps aside from weaponry, but that's probably a long, slow accretion) and not for consumption.
