This Glass Hinges Fitting is a structural component used in glass door systems. Its primary function is to securely connect the glass door to the hinge, ensuring a smooth and precise movement during door opening and closing. Model 86B1 measures 86 x 46.5 mm and features a compact design that accommodates a variety of glass thicknesses and mounting systems. In daily operation, it offers the smooth, gentle opening and closing feel of glass doors, as well as the safety and stability of its robust structure. It is commonly used in bathroom doors, glass partition doors, and display spaces.

High-Load-Bearing Design

The Glass Hinges Fitting features a 3.2mm thick SUS304 or SUS316 stainless steel body with a tensile strength of 520MPa. A single hinge base can withstand a static load of 150N, and when used with two hinges, the total support weight can reach 40kg.

Precision-Machinery

Products are manufactured using CNC machining and laser drilling processes, with hole positioning tolerances within ±0.02mm, ensuring a tight fit between the hinge and the glass. The standard 86mm length and 26.5mm depth ensure precise and symmetrical installation, effectively minimizing installation deviations.

Corrosion-Resistant and Moisture-Resistant

The SUS316 model showed no signs of rust after a 120-hour neutral salt spray test, with a surface roughness of Ra ≤ 0.8μm. Satin and polishing processes create a dense protective layer to prevent oxidation from moisture and chemicals in the air. The aluminum alloy version uses anodizing technology, achieving a surface hardness of HV220 and withstanding long-term use in environments with 95% humidity without discoloration.

Stable and Vibration-Resistant Performance

The hinge bearing is equipped with a high-density nylon sleeve with a friction coefficient of only 0.25, effectively absorbing vibrations during opening and closing. Simulated vibration tests showed no loosening or cracking at a frequency of 15Hz and an acceleration of 5g. Its stability is 30% greater than that of traditional all-metal structures, ensuring smooth door opening and closing.

Low-Noise Opening and Closing Experience

The metal and engineered nylon composite connection structure keeps noise levels below 25dB. Opening and closing tests showed that after 50,000 consecutive opening and closing cycles, the noise level increased by less than 3dB, maintaining stable performance. Low-noise operation enhances user comfort and is particularly suitable for spaces requiring a quiet environment.

Bathroom Glass Doors

In bathroom glass doors, hinge bases effectively resist oxidation corrosion caused by humid environments. The SUS316 stainless steel version remains stable even under frequent contact with steam and water vapor, ensuring the long-term safety of the glass door. Its high load-bearing capacity ensures smooth door operation and a light opening feel.

Business Glass Partitions

For glass partitions in office or conference spaces, hinge bases ensure the door's verticality remains stable. The high-precision structural design ensures a tight fit when closed, enhancing sound insulation and visual cleanliness. The sleek metal surface enhances the modern feel of the space.

Display Cabinet Door Systems

For display cabinet glass doors, hinge bases ensure precise alignment despite frequent opening and closing. The polished surface enhances reflectivity, brightening exhibits. Lightweight aluminum alloy versions reduce cabinet loads, making them suitable for applications such as shopping mall windows.

Medical and Laboratory Environments

For use in laboratories or medical facilities, the hinge bases feature a smooth, easy-to-clean surface that resists corrosion from alcohol and disinfectants. SUS304 stainless steel ensures long-term stability in dust-free and chemical-free environments, maintaining the cleanliness of glass doors and meeting hygiene and safety requirements.

Home Balcony

In home glass sliding doors, the hinge base ensures smooth and wobble-free operation. Aluminum alloy models are lightweight and suitable for residential installations. The matte Satin finish provides excellent fingerprint resistance, maintaining a long-lasting clean appearance and complementing modern, minimalist interiors.

1. What thickness of glass can the Glass Hinges Fitting be installed on?

The glass hinge base is compatible with common tempered glass doors of 8mm, 10mm, and 12mm thickness. Installation requires only the corresponding hinge assembly size. For special glass thicker than 12mm, thickened accessories or custom screw hole configurations are available to ensure stability.

2. Does installing the Glass Hinges Fitting require specialized tools?

We recommend using a dedicated glass clamp and a stainless steel torque tool for installation to ensure even tightening force. While a standard screwdriver can be used, it may cause uneven force on the screws, affecting long-term stability.

3. How do I choose the appropriate material?

The choice of the three materials should be determined based on the intended use environment: SUS304 is suitable for general indoor applications and offers excellent strength and rust resistance. SUS316, which contains molybdenum, improves corrosion resistance by approximately 40%, making it ideal for high-humidity environments such as bathrooms, swimming pools, and beaches. The aluminum alloy version offers a lightweight and refined appearance, making it more suitable for home and display spaces.

4. Will the surface finish of the glass hinge fitting darken or rust over time?

It will not discolor or rust easily. Satin or Polish finishes create a dense protective layer on the surface, significantly improving oxidation resistance. Test data shows that after 180 days in an environment with 95% humidity and 40°C, there is no noticeable color change or signs of rust.

5. How often do glass hinge bases need maintenance?

A routine inspection every six months is recommended, including checking screw tightness, bushing wear, and surface cleanliness. If the operating environment is humid or the hinge is frequently opened and closed, maintenance should be reduced to every three months. Wipe the surface with a neutral detergent and a soft cloth, and apply a moderate amount of grease to the axis to maintain smooth opening and closing and quiet operation.
