Sloss-Sheffield later became part of U.S. Pipe & Foundry. Donated to the City of Birmingham in 1971, Sloss is a preserved historic site today, also serving as a venue for various events.   Sloss iron was sold as merchant pig iron to other iron industries, sort of like  a chocolate maker selling chocolate to other candy makers.  Being close to downtown on the First Avenue Viaduct, Sloss is perhaps the best remembered of the Birmingham furnaces. This is my vote for the best Birmingham iron and steel postcard.
