carbon steel division has successfully processed its first roll of steel in its cold-rolling mill, putting into production the second major piece of the carbon steel part of the $5 billion complex.

Scott Posey, spokesman for ThyssenKrupp Steel USA, said the first roll was completed at 4:30 p.m. Monday, the conclusion of a startup process that began Saturday.

On July 31, the German steelmaker successfully processed its first coil of steel in its hot strip mill. The first major unit on the carbon steel side, it melts slabs made elsewhere and presses them into a thin strip that can be rolled up into coils.

With the cold-rolling mill on line, the carbon steel unit will now turn its attention to completing the hot-dip galvanizing line. The company expects to start the first of two such lines in December.

The separately managed stainless steel unit expects to start its first major components as early as next week, spokeswoman Mary Mullins said Thursday.
