Oversized & Heavy-Duty Door Frames
Frame systems designed around large, heavy and bespoke door leaves where standard framing is not appropriate. This page is a canonical component topic: other door pages can point here for the shared technical overview while keeping their own content focused on the specific door or project.
How this component fits into the door system
Doors work best when the leaf, frame, opening, hardware, finish and any automation are specified as connected parts. The useful route is to start with the application, then move through compatible materials, sizes, finishes and related components.
