Concealed Door Hinge for Residential Concealed Hinge for Residential fire rated concealed hinge

This heavy-duty concealed door hinge is specifically engineered for high-end residences, villas, and large-format apartments. Featuring a 180-degree ultra-wide opening, a luxurious gold finish, an 80kg load capacity, and three major international certifications, it delivers the ultimate door control solution for residential projects demanding supreme aesthetics and exceptional performance. While remaining entirely concealed, it supports and enhances every significant interior door.

1. Core Performance & Certifications (The Cornerstone of Robust Reliability)

This product transcends standard domestic hardware, achieving rigorous commercial-grade performance. Each hinge supports up to 80kg, effortlessly accommodating substantial solid wood doors, metal composite doors, or large concealed door panels. It has passed the BS EN1935 200,000-cycle fatigue test, equivalent to 50 daily openings for over a decade without failure, delivering ‘install once, worry-free for life’ reliability for residences. Simultaneously, it holds EN 1634 132-minute fire certification and EN 1670 48-hour corrosion resistance certification. This not only adds a critical safety barrier to the home but also withstands the corrosive effects of humid environments (such as kitchens and bathrooms), ensuring enduring performance.

2. Distinctive Features and Design (A Fusion of Aesthetics and Practicality)

(1) 180-Degree Ultra-Wide Opening: Enables the door panel to swing fully open, lying flush against the side wall. This significantly saves space while facilitating easy passage and furniture movement, making it particularly suitable for areas with limited space or modern designs seeking maximum openness.

(2) Three-dimensional (3D) Concealed Adjustment: Hinges are entirely concealed within the door leaf and frame, leaving no visible trace when closed to achieve a minimalist ‘door-wall integration’ visual effect. An integrated 3D adjustment system enables precise post-installation calibration of vertical alignment, flatness, and gaps, perfectly resolving misalignment issues caused by building settlement or timber warping.

(3) Luxurious Gold Finish: The surface undergoes premium gold plating, delivering a warm, opulent metallic sheen that complements various interior styles—from light luxury and new Chinese to modern minimalism. This finish also provides a robust protective layer against oxidation and scratches.

3. Superb Materials and Construction (Inherent Quality Assurance)

The hinge body is precision-cast from high-strength zinc alloy, ensuring robust structural integrity and long-term load-bearing capacity without deformation. The connecting arms utilise lightweight yet high-strength aluminium alloy, optimising force transmission efficiency while reducing door movement inertia for exceptionally smooth and silent operation. This material combination achieves the optimal balance of strength and durability.
