Magnetic decorative hardware is a less permanent option because the pieces can move over time, whether from people or the door’s vibration as it opens and closes. This may be appealing to some homeowners who want the flexibility to add or remove the decorative hardware, but for others, this may be an issue.
Magnetic hardware can only be applied to stamped steel doors since there would be no magnetic force on other materials and resembles stamped steel in terms of dimension. The pieces don’t have a lot of depth to them, as does aluminum decorative hardware.
