Invisible Aluminum-wood Interior Door

Thanks to the stability of aluminum and properly treated wood, these doors exhibit superior resistance to warping, cracking, and shrinking across diverse climates, performing well in both humid southern and dry northern regions.

Achieving visual continuity, capable of full-height designs, enhancing the sense of space and grandeur. the aluminum alloy framework and reinforcement (e.g., aluminum dragon bones/keels) provide exceptional impact resistance and prevent deformation, often boasting a lifespan for years.

The paramount feature of hidden doors is their ability to blend seamlessly into walls, cabinets or other architectural elements, maintaining a clean, uncluttered, and modern aesthetic. They often employ minimalist framing and can be finished to match surrounding surfaces exactly.

Concealed Hinges,3D Adjustable Hinges, High-grade Locks, Enables flush mounting and invisible integration. Allows for precise alignment after installation. Ensures smooth, silent operation and enhanced security.
