"The Steel Curtain" refers to the defensive line from the Steelers in 1970s. That defence helped win the team four Super Bowls in that decade.
Built on the site of the former Log Jammer flume.
Kennywood states the Steel Curtain has nine inversions. This differs from the rcdb's listing of eight. It's thought that Kennywood is counting the Banana Roll element as two inversions while rcdb counts this element as a single inversion. Prior to the Steel Curtain the Banana Roll had only existed on one other roller coaster, the Takabisha built in 2011, at Fuji-Q Highland in Japan. Fuji-Q Highland has always listed the Takabisha as having seven inversions. Looking at the Takabisha's other inversions, they are counting the Banana Roll as a single inversion.
'Steel Curtain' is the centerpiece of 'Steelers Country', a new themed area based on the city's professional football team, the Pittsburgh Steelers. The roller coaster's logo and name make reference to the local steel industry.
