A worker operates the levers of a washer unit
on the production line of the tin-plate mill. The razor-sharp steel
ran through
the machinery at about 500 feet per minute. Most of Sparrows
Point’s tin plate (actually steel with a microscopic coating
of tin) was sold to make cans for Campbell’s Soups, Dole’s
Hawaiian Pineapple Company, and such beer makers as Anheuser-Busch
and Pabst.
