The exact construction of hollow metal doors varies by manufacturer, but two types of designs are common. One uses a tubular framework over which the face panels are welded. Insulation and sound-deadening material are placed in the hollow core. Another type uses a core material, such as kraft paper honeycomb, polyurethane, polystyrene, a steel grid, mineral fiberboard, or vertical steel stiffeners, over which metal panels are bonded.
