Steel Dynamics has announced an additional investment of $75 million to install a second caster at its Structural and Rail Division at Columbia City, Ind. The expansion will help to facilitate production of larger quantities of semi-finished steel, increasing the mill's combined production capacity for structural steel and rail to 2 million tons/year.

The initial installation will comprise four strands, but the new bloom/billet caster will be expandable to five strands in the future as warranted by market conditions. Installation of a second caster complements a previously announced $200 million mill expansion that is currently underway at the Columbia City facility. The new caster is scheduled to be completed in the fourth quarter of 2008.
