Abstract
A door system and a method of making a door system including a metal door, a metal door frame for the metal door, and one or more door frame seals. The metal door and the metal door frame each include a steel outer surface with a first metal layer in contact with and that encapsulates or covers the steel outer surface, and a second metal layer in contact with and that encapsulates or covers the first metal layer. The first metal layer is different from the second metal layer. The first metal layer can be optional. The door frame seals are located on the metal door frame and provide conductivity between the metal door and the metal door frame. The door system preferably has an acceptable sound transmission class rating and RF shielding properties.
