Oregon Steel Mills, Inc. (OSM) is a subsidiary of the Russia steel producer Evraz Group S.A. and has operations in Portland, Oregon, United States, and also with facilities in Colorado and Alberta. Operated as Evraz Oregon Steel Mills, Inc., the company produces items such as structural tubing, pipes, and steel rails.


OSM operates a variety of steel production facilities. These include a plate mill at their OSM Rolling Mill at the Portland Steelworks in Portland, Oregon.[3] OSM manufactures armor plating for the U.S. military.[4] Also at the Portland Steelworks is OSM Tubular that makes pipes for use in areas such as oil and natural gas transmission, this plant was closed in 2015.[5] Oregon Steel’s Canadian operations also produce tubular steel products.[6] In Oregon, OSM also operates a structural tubing facility, the only producer in the Northwest, this plant was sold in 2015.[7]

In Colorado, OSM’s Rocky Mountain Steel subsidiary operates three production facilities.

These facilities were part of the Colorado Fuel and Iron Company, founded in 1881 and bought by OSM in 1993.[8]

In 1987 the company became Oregon Steel Mills.[9] Then in 1993 OSM purchased Colorado Fuel and Iron.[10] In January 2007 Evraz Group S.A. of Russia bought OSM for $2.3 billion.[11] Prior to this Oregon Steel was traded on the NYSE as OS.
