Alton Steel to close, cites competitive disadvantages
Written by David Schollaert
Alton Steel Inc. (ASI), a special bar quality (SBQ) steel producer, said it will close operations later this week. The move brings an end to nearly a quarter century of steel production in Alton, Ill.
The privately held company cited aging infrastructure, intense market competition, and industry consolidation as the primary forces behind the decision.
