From a base of nine models and more than 20 designer top sections, Steelhouse offers more than 200 unique configurations to ensure distinction from one home to the next.

To further enhance the door's strength, four-inch wide, two-sided steel insulated boards are bonded with epoxy cement and mechanically fastened to ensure positive attachment to the face of the door.
