Interior door concealed hinges employ a zinc alloy monobloc die-casting process, having passed the EN 1395 standard's 200,000 opening/closing cycle test and the stringent EN 1634-1 fire resistance certification for 132 minutes. They combine corrosion resistance with three-dimensional precision adjustment functionality. The concealed design achieves seamless integration between door frame and leaf, enhancing spatial aesthetics and security. Suitable for commercial premises, public buildings with stringent fire safety requirements, and humid environments, these hinges redefine interior door hardware standards through long-term durability and fire resistance.

Core Performance Certification:
Exceptional Durability:
*Passed the rigorous 200,000-cycle test under European Standard EN 1935 (Durability Testing for Building Hardware), ensuring sustained stability in high-frequency operation scenarios (e.g., commercial premises, public buildings) with a lifespan far exceeding industry norms.
*Superior Fire Resistance: Complies with EN 1634-1 fire testing standards, successfully withstanding 132 minutes of high temperatures and flame exposure in simulated fire conditions. Maintains structural integrity and functionality, providing critical escape time for occupants.
*Material Enhancement: Features a high-strength zinc alloy body combined with precision die-casting technology, balancing lightweight construction with impact resistance. The surface undergoes anti-corrosion treatment, ensuring longevity in demanding environments such as humidity and salt spray.
Design Highlights:
*Concealed Installation: The concealed hinge mechanism is fully integrated into the door frame and leaf, presenting a clean aesthetic with no exposed components, enhancing both architectural aesthetics and security.
*Precision Adjustment: Supports three-dimensional adjustment (vertical/horizontal/front-to-back) to ensure seamless door-to-frame alignment, reducing noise and enhancing sealing performance.
*Universal Compatibility: Compatible with timber doors, steel doors, fire doors and other materials, supporting flexible left/right and inward/outward opening configurations.
*Public buildings with stringent fire safety requirements (hospitals, schools, airports)
*Humid or corrosive environments (coastal regions, industrial facilities)
