Interior of the Tin Plate Mill in McKeesport, Allegheny County in the 1900's.
[The workers who inspected the sheets were called tin floppers because they would have to turn a sheet over to inspect the other side. Judging from the number of grandmothers and mothers and their sisters mention as floppers, inspection must have been women's work.]

It started in 1903. [nytimes]

"The Steelmet plant was built as the McKeesport Tin Plate Company at the turn of the 20th century, and by the 1920s, ranked as one of the world's leading producers of tin-plated steel, which was used for (among other things) canned goods. It also made McKeesport businessman Edwin Crawford one of the wealthiest people in Pennsylvania." [TubeCityOnline_525]

The plant became part of J&L. [TubeCityOnline_1651]
