From its founding in Chicago in 1954, Feralloy Corp. has grown to become the USA's largest processor of hot rolled sheet. With five processing plants and seven joint venture facilities, Feralloy is part of Reliance Steel and Aluminum and serves manufacturers and processors across the USA and Mexico.

Feralloy produces SCS sheets at its ISO-9001:2000 certified plant in Charleston, South Carolina. Located on the campus of Nucor's Berkeley, SC mill, the Charleston Division can accept and ship material by truck, rail and barge/vessel. Built in 1999, this modern facility offers slitting, cut-to-length and, since 2007, SCS sheet processing.
