Frameless Glass Hinges are key connectors installed in frameless glass doors, supporting and controlling their opening and closing. Their precision mechanical design ensures smooth and stable opening and closing, preventing deflection or loosening. Their square, simple appearance and straight lines make them popular in modern bathrooms, office partitions, and commercial display spaces. Constructed primarily of high-strength stainless steel, these hinges feature anodized aluminum components and a smooth brushed finish, enhancing their load-bearing and corrosion-resistant properties while ensuring long-term aesthetics and safety.

High Load-Bearing Capacity

Frameless Glass Hinges utilize a one-piece, thickened SUS304 stainless steel structure, 6mm thick, with a tensile strength of 520MPa. A single hinge can withstand a load of 400N, and two hinges installed together can support a 40kg glass door. The optimized internal load-bearing surface evenly distributes torque, reducing glass sag to less than 0.8mm. After long-term use, the structural deformation rate is less than 0.15%, significantly extending the product lifespan.

Precision Rotating Shaft System

The core rotating shaft utilizes a high-precision stainless steel core with a clearance of only 0.02mm. The opening and closing angles are controlled to within ±1.5°, and the rotational resistance torque is maintained between 0.9–1.1N·m. After 100,000 opening and closing cycles, the hinges remain smooth and free of binding, with only 0.03mm of shaft wear. This precision system ensures smooth and effortless opening and closing of the glass door, with noise levels below 25dB.

Excellent Corrosion Resistance

SUS316 models pass a 120-hour salt spray test with no red rust and a surface roughness of Ra ≤ 0.8μm, offering excellent rust resistance. A combination of satin brushing and polishing creates a double-layer protective film structure with a surface oxide film thickness of 0.9μm. This effectively withstands high humidity and chloride environments, making it particularly suitable for use in bathrooms or coastal areas.

Stable Clamping System

The clamping surface utilizes 2mm thick EPDM high-elasticity, non-slip rubber pads with a coefficient of friction exceeding 0.78, ensuring a secure grip on the glass. M6 stainless steel screws are used, with a recommended tightening torque of 9 N·m. The clamping surface is 43mm wide and 131mm long, ensuring uniform force distribution on the glass and preventing chipping and slippage.

Precision Surface Finish

The surface utilizes a dual-processing process: the satin brushing layer creates a delicate matte texture, while the polished layer achieves a gloss of 60%. The surface hardness is HV210, increasing scratch resistance by 35%. CNC machining accuracy tolerances within ±0.1mm, resulting in a smooth edge transition.

Effective Installation and Adaptability

The hinge features standardized mounting dimensions, suitable for glass thicknesses from 6mm to 12mm. The clamping depth and screw hole distance have been repeatedly tested, ensuring an installation tolerance of no more than ±0.5mm, ensuring precise closing after assembly. It supports both horizontal and vertical mounting options, accommodating a variety of door configurations. The streamlined installation process reduces construction time by 30%, improving project efficiency.

Home Shower Spaces

When used in residential shower rooms, Frameless Glass Hinges ensure smooth and secure opening and closing of glass doors. The precise axis structure ensures precise opening and closing angles, effectively preventing moisture leakage. Even in long-term humid environments, the SUS316 surface remains rust-free and maintains a clean bathroom appearance.

Hotel Bathroom Systems

Shower areas in high-end hotels often require extremely high opening and closing performance. This hinge, with its precise pivot and silent structure, ensures smooth opening and closing. Its anti-corrosion surface treatment ensures continuous use for over five years in environments with humidity levels up to 95%. This enhances the durability and user comfort of hotel facilities.

Office Partitions

In business spaces, the hinges can support glass doors up to 900mm wide, ensuring consistent door alignment and angles. Its low-resistance rotation system ensures stable opening and closing, reducing wear on the door frame. Its square design and matte finish complement the minimalist style of modern office spaces, balancing practicality and aesthetics.

Display Windows and Showcases

In commercial display areas, this hinge ensures smooth rotation and precise positioning of glass doors. The mirrored surface enhances light reflection, highlighting the displayed content. Testing shows its fatigue resistance is 25% higher than standard hinges, making it suitable for high-frequency opening and closing.

Public Changing and Swimming Pool Areas

In swimming pools and changing areas with high humidity and salty air, this hinge provides excellent corrosion resistance. Even after long-term use, the surface shows no signs of oxidation, and the structure remains stable and free of loosening. Even in high-temperature and high-humidity environments, the opening and closing resistance does not change by more than 0.05 N·m.

1. What glass thicknesses are compatible with frameless glass hinges?

The standard clamping range for frameless glass hinges is 6mm to 12mm, meeting the requirements of common shower enclosures, partition doors, and display cabinets. They are ideally suited for glass up to 10mm thick, ensuring even force distribution and high stability.

2. Do I need to drill holes when installing frameless glass hinges?

No additional holes are typically required during installation. This product uses a clamping mechanism, creating friction between the EPDM non-slip rubber pad and the stainless steel clamping surface for a secure hold. Standard installation ensures the integrity of the glass. Customized drilling is required for specialized designs (such as glass doors with positioners).

3. Are frameless glass hinges adjustable or self-closing?

This series of hinges features a standard mechanical hinge design, supporting a free opening angle range of 90° to 180°. Some models offer optional cushioning or self-closing components to automatically return the door to its closed position. If precise closing angle control is required, fine-tuning can be achieved by adjusting the mounting base, with a maximum adjustment range of approximately ±2°, ensuring the door is parallel to the wall and closes tightly.

4. Are hinges susceptible to rust in humid environments?

The hinge body is made of SUS304 or SUS316 stainless steel with a satin or polish finish, offering corrosion resistance in environments with humidity up to 95%. Salt spray testing has proven that the SUS316 model showed no red rust after 120 hours. Even in high-humidity environments such as bathrooms and swimming pool changing areas, it maintains its metallic luster and mechanical stability.

5. What should I do if the glass door sags slightly during use?

If the door sags, it can be corrected by repositioning the hinge clamps. First, loosen the fixing screws, gently lift the door, and realign the horizontal alignment. Then, re-tighten to the recommended torque. It is recommended that the distance between the upper and lower hinges be between 700mm and 800mm during installation to ensure overall support.
