U.S. Steel Tower
The U.S. Steel Tower, also known as the Steel Building, or USX Tower (1988–2001), is a 64-story skyscraper at 600 Grant Street in downtown Pittsburgh, Pennsylvania. The interior has 2,300,000 sq ft (210,000 m2) of leasable space. At 256.3 m (841 ft) tall, it is the tallest building in Pittsburgh. It held its opening dedication on September 30, 1971.
The tower's original name when completed was the U.S. Steel Tower and was changed to USX Tower in 1988. The name was changed back to the U.S. Steel Tower in January 2002 to reflect U.S. Steel's new corporate identity (USX was the 1990s combined oil/energy/steel conglomerate). Although no longer the owner of the building, U.S. Steel remains one of the largest tenants.
Prior to 1970, the tallest building in Pittsburgh at 44 stories was the Gulf Building (now known as the Gulf Tower). In the planning stages, U.S. Steel executives considered making the building the world's tallest, but settled on 840 ft (260 m) making it the tallest building outside New York and Chicago. However, it eventually lost even that distinction to newer buildings erected across the United States.
The building contains over 44,000 U.S. tons (40,000 metric tons) of structural steel, and almost an acre of office space per floor. The U.S. Steel Tower is architecturally noted for its triangular shape with indented corners. The building also made history by being the first to use liquid-filled fireproofed columns. U.S. Steel deliberately placed the massive steel columns on the exterior of the building to showcase a new product called Cor-ten steel. Cor-ten resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and doesn't need painting and costly rust-prevention maintenance over the years. The initial weathering of the material resulted in a discoloration of the surrounding city sidewalks, as well as other nearby buildings. A cleanup effort was orchestrated by the corporation once weathering was complete to undo this damage, but the sidewalks still have a rusty tinge. The Cor-Ten steel for the building was made at the former U.S. Steel Homestead Works.
Rockwell International, which had its headquarters in the building, displayed a large model of the Rockwell-designed NASA Space Shuttle in the building's lobby until the company moved its headquarters to Southern California in 1988.
In May 1986, two men parachuted off the roof of the tower before being arrested by Pittsburgh Police near the Civic Arena.
In 2014, US Steel announced its intention to build new office space at the adjacent site of the former Civic Arena.
The largest occupancy by a tenant of the building is held by UPMC, which leases 500,000 square feet (46,000 m2) of office space within the tower. In 2008, UPMC added signage, lights displaying "UPMC," to the top of the tower for the first time in its history, a move that was criticized by some involved in the construction of the structure.
