Overview
The Mon Valley Works is one of five integrated steelmaking facilities operated by U. S. Steel, and consists of three operating plants: Edgar Thomson Plant, Irvin Plant, and Fairless Plant. Sheet products from Mon Valley Works serve customers in the appliance, automotive, metal building, and home construction industries. 

The Edgar Thomson Plant, located about 10 miles southeast of Pittsburgh in Braddock, Pa., is where basic steel production takes place at Mon Valley Works. Steel slabs from Edgar Thomson are sent by rail to the nearby Irvin Plant in West Mifflin, Pa., where they are rolled into a number of different sheet products. Major sheet products manufactured at the Irvin Plant include hot rolled, cold rolled, galvanized, and Galvalume coated sheet in addition to products for special applications, such as embossed sheet, vitrenamel sheet, and commercial bright sheet.

At the Fairless Plant, a finishing facility outside Philadelphia in Fairless Hills, Pa., hot rolled band is finished into galvanized sheet.
