Logos and uniforms of the Pittsburgh Steelers
Logo
The team's current primary logo was introduced in 1962 and is based on the flag originally designed by Pittsburgh's U.S. Steel and now owned by the American Iron and Steel Institute (AISI). Ironically, it was Robert Sexton, an employee out of the Pittsburgh office of Cleveland-based Republic Steel, that suggested the Steelers adopt the industry logo. It consists of the word "Steel" surrounded by three astroids (hypocycloids of four cusps). The original meanings behind the astroids were, "Steel lightens your work, brightens your leisure, and widens your world." Later, the colors came to represent the ingredients used in the steel-making process: yellow for coal, orange for iron ore, and blue for scrap steel. While the formal Steelmark logo contains only the word "Steel," the team was given permission to add "ers" in 1963 after a petition against AISI.
