Rocky Mountain Steel inks 7-year deal with Union Pacific Railroad
Written by Ethan Bernard
Rocky Mountain Steel Mills has signed a new seven-year contract with Union Pacific Railroad for the domestic production of steel rails.
Pueblo, Colo.-based Rocky Mountain Steel expects to begin operations this year at a new, long rail mill, constructed with a more than $1 billion investment in domestic steel production.
The company said the new mill remains the only “dedicated steel rail mill in the United States.”
The deal marks Union Pacific’s commitment to buying a majority of its rail from a US manufacturer. Further terms were not disclosed.
“This mill is an essential part of America’s steel transportation infrastructure, and its continued existence shows that our nation offers railroads large and small the very best product,” Doug Matthews, CEO of Orion Steel, the parent company of Rocky Mountain Steel, said in a statement on Wednesday.
Recall that Greenwich, Conn.-based private equity firm Atlas Holdings completed its purchase of Evraz North America and its subsidiaries last July. The steelmaker now operates under the name Orion Steel Companies.
