The United Steelworkers --- whose formal name is the United Steel, Paper & Forestry, Rubber, Manufacturing, Energy, Allied Industrial & Service Workers International Union --- is the largest industrial labor union in North America, with over 700,000 members.

Opened in 1963, the union's eye-catching, 13-story national headquarters was the first exterior space frame building ever constructed, with a diagonal-grid load-bearing steel wall.

Meeting space within the building is sometimes opened for industry or public events.

Hours of operation

The offices are normally open Monday through Friday, 9:00 a.m. to 5:00 p.m.


The building has its own indoor parking garage, operated by the Parkway Corporation, with space for 112 vehicles. For more information, call (412) 690-5170.
