Product Features
1. Robust Durability
This concealed door hinge holds EN1935 certification, having passed 200,000 opening/closing cycles with continued smooth operation – significantly exceeding industry standards. The hinge body is cast from high-strength zinc alloy, offering exceptional load-bearing capacity and deformation resistance. Aluminium alloy connecting plates reduce weight while maintaining structural integrity. A stainless steel cover plate further enhances impact resistance. These Concealed Door Hinges remain reliable in high-frequency usage environments, making them suitable for high-traffic locations.
2. Fire Safety
Certified to EN1634 fire standards, the product withstands 132 minutes of high-temperature exposure, ensuring the door maintains structural and functional integrity during a fire. Fire-resistant expansion seals between the hinge cup and arm automatically expand when heated, effectively blocking smoke and flame propagation. Constructed from high-temperature resistant metals, they prevent melting or deformation. These fire-rated Concealed Door Hinges serve as critical hardware for ensuring safe evacuation and protecting property.
3. Superior Corrosion Resistance
Meeting EN1670 standards, the hinges undergo 48-hour salt spray testing without exhibiting red rust or coating peeling, achieving the highest level of corrosion protection. The gold-plated finish not only lends an elegant appearance but also enhances resistance to oxidation and moisture corrosion. The combination of zinc alloy and aluminium effectively prevents electrochemical corrosion. These Concealed Door Hinges are particularly suitable for indoor environments with high humidity or frequent chemical cleaning.
4. Precise Adjustment
Featuring three-dimensional adjustment: depth adjustment ±2mm, height adjustment ±1.5mm, lateral adjustment ±1.2mm. This allows post-installation fine-tuning to eliminate door leaf misalignment. All adjustments are completed using a single screwdriver without component disassembly. Precision-machined components with clearances under 0.1mm ensure smooth, silent door operation. These Concealed Door Hinges significantly enhance installation efficiency and long-term door stability.
5. Aesthetic Integration
The champagne gold finish harmonises with most interior décor styles, projecting a premium quality. The fully concealed design ensures no hardware is visible when the door is closed, maintaining visual purity and unity within the space. Clean lines and an integrated hinge arm-to-cover plate construction minimise dust accumulation and facilitate easy cleaning. These Concealed Door Hinges represent the ideal detailing accessory for achieving modern minimalist interior design.
