Birdsboro "Five over Four" Steel Mill Roller Leveler

*This machine was constructed in 1945 for the purpose of leveling heavy armor plating. It was installed in 1947 after the war and then bought and set up in the Midwestern United States in 1989 at another steel mill. It is up and in operation. We were told that Birdsboro does not produce levelers this large anymore, and this one may be the largest in existence. Please contact us for additional information and inspection. We'll be happy to make an appointment to have you see the machine in operation. Our e-mail address is: Our contact phone number is: (630) 229-3926. Ask for John.
