Glass Door Hinges Fitting is a structural component used to connect and secure hinges in glass door systems. It provides support, positioning, and cushioning during the door's opening and closing process. Manufactured from a stainless steel or aluminum alloy composite, it is compatible with a variety of glass door hinges. Its compact mounting structure, measuring 83 x 45.5 mm, securely connects the door to the frame, ensuring smooth operation. It is widely used in commercial glass doors, display cabinet doors, shower doors, and high-end building partition systems.

High-Strength Support Structure

The Glass Door Hinges Fitting utilizes a 3mm thick SUS304 stainless steel main structure with a tensile strength of 520MPa. The core load-bearing areas are CNC-machined with an accuracy of ±0.05mm. A single hinge base has a load capacity of 150N and can support glass 8–10mm thick. When used with upper and lower hinges, it can support a maximum load of 40kg.

Composite Material Design

This product combines SUS316 stainless steel with anodized aluminum, increasing surface wear resistance by approximately 35%. Its surface hardness reaches HV230, providing excellent impact resistance. The internally assembled nylon bushing has a low coefficient of friction of 0.25, effectively reducing metal wear. The composite material construction reduces product weight by 15%, making installation easier while maintaining robust performance.

High-Precision Connection Holes

The connection holes are laser-cut with a diameter tolerance of no more than ±0.02mm, ensuring a precise fit with the hinge. The standard 83mm mounting hole spacing makes it compatible with a variety of glass door hinge models. Dynamic load testing has proven that hole deformation under a 300N impact load is less than 0.05mm, ensuring precise positioning during door opening and closing.

Excellent Corrosion Resistance

A dual surface treatment process of Satin and Polish ensures a surface roughness of Ra ≤ 0.8μm, and no rust after a 120-hour salt spray test. The metal surface remains smooth and clean after long-term testing in a 95% humidity environment. The use of SUS316 material ensures long-term stable operation in coastal areas, bathrooms, and around swimming pools, unaffected by oxidation.

Low-Noise Operation System

Equipped with a POM high-density nylon bushing, this system effectively reduces friction noise. Measured opening and closing noise levels are less than 22dB, approximately 45% lower than traditional metal hinge bases. The nylon bearing wear depth is less than 0.03mm after 50,000 opening and closing cycles, ensuring long-term quiet operation. This low-noise structure significantly enhances the overall door system experience.

Exquisite Surface Finish

Utilizing multiple precision polishing processes, the Polish layer achieves a gloss of 70%, while the Satin brushed layer increases scratch resistance by 30%. The surface is highly resistant to stains, showing no scratches or gloss loss after an alcohol wipe test. CNC rounded edges prevent cutting glass or injuring installers, demonstrating precision machining and safety.

Office Glass Doors

In office spaces, hinge bases support heavy-duty glass partition doors. High-precision positioning keeps the door's opening and closing angle within ±1.5°, maintaining a tight seal. This ensures smooth door opening, reduces friction between the door frame and the floor, and extends system life.

Shopping Mall Display Windows

When used in shopping mall cabinets or display doors, hinge bases ensure glass doors remain stable despite frequent opening and closing. The polished surface enhances visual reflection, adding a premium feel to the display environment. Its high wear resistance ensures smooth operation even with hundreds of daily openings and closings.

Hotel Bathroom Glass Doors

In high-humidity environments, the hinge base's corrosion resistance protects its structure from moisture. SUS316 stainless steel maintains its strength even under temperature fluctuations, preventing loosening or discoloration, making bathroom doors safer and more reliable.

Medical and Laboratory Partitions

This product is widely used in clean rooms and laboratory spaces. Its low-noise structure and high-precision fit reduce environmental vibration. Its chemical resistance makes it resistant to common disinfectants and cleaning solutions, maintaining its structural integrity over time.

Home Sliding Glass Door

When installed in a balcony or kitchen glass door system, it ensures smooth and effortless operation. The wear-resistant design reduces track resistance, ensuring smooth opening and closing. Users will experience noticeably quiet opening and closing, along with long-lasting structural support.

Regular Cleaning and Maintenance

We recommend wiping the surface weekly with a neutral detergent to remove dirt and fingerprints. Keeping it clean prevents corrosion deposits and maintains the metallic luster. Avoid using steel wool or acidic solutions when cleaning to prevent scratches.

Checking Connections

Every six months, check the hinge base and shaft for a secure connection, ensuring the screw torque is maintained at 9 N·m. If slight misalignment is detected, readjust the holes to ensure the glass door is balanced.

Lubricating Friction Areas

Every 12 months, add 0.2g of silicone-based grease to the nylon bushing to reduce friction and prevent dry wear. After lubrication, wipe off any oil residue with a dry cloth to maintain smooth opening and closing and minimize noise.

Moisture and Mold Prevention

In areas with high humidity, it is recommended to spray a moisture-proof protective agent quarterly to create a transparent protective film. This effectively reduces metal oxidation and maintains the hinge base's glossiness.

Checking for Wear and Replacement

Inspect the nylon bushing and fixing components annually for wear. If loose or deformed, replace it immediately. Keeping all components in good condition can extend the safe service life of the entire glass door system.
