Technical Specifications
1. Dimensions and Weight
Product dimensions are 28x177mm, specifically engineered for heavy-duty doors. Each hinge supports up to 80kg, ensuring suitability for various substantial fire doors and solid wood doors. Weight is precisely calculated to guarantee structural integrity while facilitating installation and adjustment.
2. Material Composition
The hinge body utilises high-strength zinc alloy, delivering exceptional resistance to compression and deformation. The connecting plates utilise aluminium alloy, reducing weight while maintaining stability. The surface is covered with a stainless steel cover plate, enhancing durability and corrosion resistance.
3. Certification Standards
Certified to EN1935, having completed 200,000 opening/closing cycles to ensure an exceptionally long service life. EN1634 fire certification provides 132 minutes of fire protection. EN1670 corrosion resistance certification passed 48-hour salt spray testing, guaranteeing reliability in humid environments.
Product Features and Advantages
1. Exceptional Load-bearing Capacity
This Heavy Duty Concealed Hinge employs a high-strength zinc alloy body and precision structural design, with each hinge supporting up to 80kg – significantly exceeding standard hinge load capacities. Its unique force distribution system ensures even weight dispersion, preventing localised stress concentration. It is particularly suitable for large fire doors and solid wood doors.
2. Fire Safety Performance
Certified to EN1634 standards with 132-minute fire resistance testing. The integrated fire-resistant expansion seal automatically expands under high temperatures, effectively blocking the spread of flames and smoke. This Heavy Duty Concealed Hinge maintains the structural integrity of doors during fires, providing crucial time for safe evacuation.
3. Precise Three-Dimensional Adjustment
Features an advanced three-dimensional adjustment system allowing ±2mm vertical adjustment, ±1.5mm horizontal adjustment, and ±1.2mm depth adjustment. Installers can achieve precise alignment without removing the door leaf, significantly reducing installation time and maintenance costs. With an adjustment accuracy of 0.1mm, this Heavy Duty Concealed Hinge ensures long-term perfect alignment of the door leaf.
4. Exceptional Corrosion Resistance
Certified to the highest EN1670 corrosion resistance standard, exhibiting no signs of corrosion after 48 hours of salt spray testing. The surface undergoes a multi-layer electroplating process, featuring a nickel base layer followed by surface treatment, with a total coating thickness of 15μm. This Heavy Duty Concealed Hinge is particularly suited for coastal regions and high-humidity environments.
5. Long-Term Durability
Certified to EN1935 standards with 200,000 cycle testing, equivalent to over 25 years of daily use. Incorporates a self-lubricating bearing system requiring no routine maintenance. This Heavy Duty Concealed Hinge offers over three times the durability of standard hinges, significantly reducing long-term operational costs.
Application Scenarios and Value
1. Commercial Complex Fire Doors
Large shopping centres and office buildings require reliable fire safety systems. This Heavy Duty Concealed Hinge provides 132 minutes of fire protection and meets the load-bearing requirements for large fire doors. Its concealed design maintains spatial aesthetics, while three-dimensional adjustment enables rapid door alignment correction, reducing maintenance costs.
2. Hospital Operating Theatre Doors
Medical environments demand exceptional door sealing and reliability. This product delivers outstanding fire resistance and corrosion protection, withstanding disinfectant exposure. Its concealed design eliminates hygiene dead zones, meeting hospital infection control standards. Precise adjustment ensures door leaf sealing, maintaining indoor pressure differentials.
3. Premium Hotel Guest Rooms
Star-rated hotels prioritise quality details and guest experience. This Heavy Duty Concealed Hinge's hidden design maintains a clean façade, while silent operation enhances accommodation comfort. Its extended service life reduces maintenance frequency and lowers operational costs.
4. Educational Institution Security Doors
Schools require durable and secure door control solutions. This product passes 200,000-cycle durability testing, with fire resistance meeting safety standards. The concealed design prevents student collisions, while three-dimensional adjustment compensates for building settlement, ensuring consistent door functionality.
5. Industrial Plant Entrance Doors
Industrial environments demand exceptional door durability. This Heavy Duty Concealed Hinge's corrosion resistance adapts to harsh conditions, and its superior load-bearing capacity meets large industrial door requirements. Reduced replacement frequency significantly lowers long-term operational costs.
