Concealed Door Hinge

The hidden hinge of a wooden or metal door is a concealed hardware system installed inside the door and frame, making it invisible when closed. Unlike traditional visible hinges, it offers a clean and seamless appearance while providing excellent features such as 3D adjustability (height, depth, and lateral alignment) and soft closure mechanism. These hinges are commonly used in modern interior design, high-end cabinets, and building doors, where aesthetics and precision are important. For fire-resistant metal doors, dedicated concealed hinges (such as hinges certified by EN1634) maintain safety compliance without compromising minimalist design. Their durability (typically tested for over 200,000 cycles according to EN1935) ensures long-term reliability for residential and commercial applications.
