Meet Bally...

There's a lot of people that go into a Bally panel...

 Mike, Marcus, Avery, and Gerald are getting the autoline ready for another coil of metal.  This is the start of the process to manufacture the outside metal skins of the Bally panels.

Joseph moves a finished metal skin along its trek to become a Bally panel

Tommy and Jimmy prepare to foam-in-place the panels by fitting the metal skins and diaphragmatic speed loks into heated steel molds.  They will  then inject the molds with liquid urethane. 

All Bally doors start with a structural steel frame with steel reinforcements. Here, George continues work on a Bally door.  Various options such as observation window, pressure relief ports, special hardware are all available.
