For all you metal heads and sports fans, the American Iron and Steel Institute (AISI) has revealed the history behind the Pittsburgh Steelers helmet logo in time for the upcoming Super Bowl between the Steelers and the Arizona Cardinals this Sunday.

According to AISI, the Steelers adopted the logo in 1962, borrowing it from the institute’s Steelmark logo.

“The Steelmark was originally created for United States Steel Corporation to promote the attributes of steel:  yellow lightens your work; orange brightens your leisure; and blue widens your world.  The logo’s meaning was later amended to represent the three materials used to produce steel:  yellow for coal; orange for iron ore; and blue for steel scrap.”

Feel free to drop this nugget of trivia at your Super Bowl party this weekend.
