Concealed Frame Door

The Concealed Frame Door is an interior door system with a recessed frame, concealed hinges, and flush door leaf for a minimal visible-frame appearance. Its composite door construction can be supplied with a graphene-based core, coordinated wall finishes, and project-specified hardware for residential, hotel, bathroom, bedroom, and commercial interiors. 

Recessed Door Frame
The frame is positioned behind the finished wall surface so the door leaf can sit visually within the wall plane without a conventional exposed casing.
Concealed Hinges
Hinges are installed between the door leaf and concealed frame, keeping the hinge bodies out of direct view when the door is closed.
Project-Specified Hardware
Opening direction, lock preparation, and concealed hardware can be specified according to the door schedule and installation requirements. 

Composite Door Construction
The door leaf combines composite board materials with solid-wood structural components to form the main door structure and provide reinforced fixing areas.
Graphene-Based Core
A graphene-based composite filling is used as the internal core option for this door construction. Core thickness and configuration can be specified according to the door design.
Interior Humidity Applications
The composite construction can be specified for interior areas exposed to normal humidity variation. Suitability for bathrooms or other high-humidity locations should be confirmed against the complete door and finish specification.
Assembly-Dependent Performance
Sound, thermal, moisture, and dimensional performance depend on the complete door construction, frame, seals, finish, and installation method rather than the core material alone. 

Wall-Matched Finish
Melamine paper or PVC veneer can be selected to coordinate the door surface with painted walls, wood panels, wardrobes, cabinets, and other interior finishes.
Flush Wall Appearance
The recessed frame and flush door leaf minimize visible frame elements, allowing the door opening to visually continue the surrounding wall surface.
Integrated Wall Systems
The door can be incorporated into continuous wall paneling, feature walls, storage areas, and other interior systems where the door needs to remain visually discreet.
Typical Project Areas
The system can be specified for bedrooms, bathrooms, hotel rooms, residential interiors, offices, and other architectural spaces requiring a concealed door appearance. 

Material & Component Check
Door boards, solid-wood components, core materials, frames, hinges, locks, and other specified components are checked against the approved product configuration before assembly.
Door Leaf Assembly
The door structure is assembled with the specified core and reinforcement components, followed by machining for hinges and hardware.
Frame & Hardware Fit
Frame dimensions, hinge positions, lock preparation, and hardware locations are checked before final assembly.
Door Alignment
The assembled door is checked for frame alignment, door-to-frame clearance, hinge movement, and opening direction.
Surface Quality
Finished surfaces are inspected for scratches, uneven finishing, edge damage, visible defects, and other appearance issues.
Final Configuration Check
Model, dimensions, finish, opening direction, hardware, quantity, and other order-specific requirements are verified before packing. 

Product Drawings
Technical drawings can be provided to confirm door leaf dimensions, frame dimensions, concealed hinge locations, and installation clearances.
Installation Information
Installation documentation can cover frame positioning, door alignment, wall finishing sequence, and other configuration-specific requirements.
Project Drawing Review
For project orders, supplied door schedules and architectural drawings can be reviewed to confirm dimensions, handing, wall conditions, finish, and hardware preparation before production.
