The Glass Door Pull Handle is a fixed opening and closing device installed on glass doors, allowing for manual opening and closing. It measures 500 mm in length, with a center-to-center distance of 400 mm, a diameter of 30 mm, and a spacing of 75 mm. Its double-bolt connection ensures a secure installation and even force distribution during operation. The resulting visual effect is simple and modern, blending seamlessly with the glass door and enhancing the overall quality of the space. It is suitable for both commercial and residential environments.

Stable Construction

The Glass Door Pull Handle is 500mm long with a center distance of 400mm and is constructed from 30mm diameter solid stainless steel tubing. Mechanical testing has shown that deformation is less than 0.25mm under a tensile force of 800N, and its torsional strength reaches 70Nm. The dual-support mounting structure ensures even force distribution, preventing loosening or shifting over time, and ensuring stable opening.

Material Properties

This product is made of SUS304 or SUS316 stainless steel, with tensile strengths of 515 MPa and 530 MPa, respectively, and yield strengths exceeding 205 MPa. SUS316 contains 2% molybdenum, which improves chloride corrosion resistance by approximately 45% compared to SUS304, making it suitable for long-term use in humid and salty environments. The metal's high density makes it resistant to oxidation, ensuring a service life of over 10 years.

Surface Finish

The surface is available in either satin or mirror polish. The matte surface has a roughness of approximately 0.6 microns (Ra), providing a smooth, non-slip feel; the mirror surface has a roughness of approximately 0.15 microns (Ra), providing a uniform, bright appearance. After acid pickling and passivation, a protective film approximately 3 nanometers thick forms on the surface, which passed a 96-hour neutral salt spray test with no signs of corrosion.

Installation Precision

The threaded mounting structure allows for a hole pitch tolerance of ±0.05 mm. Post-installation deviations are limited to 0.2 mm, ensuring vertical symmetry of the handle. Tested for 100,000 push-pull cycles, the connection remains free of looseness or displacement, ensuring long-term stable mechanical properties and visual alignment.

Comfortable Operation

The 30 mm diameter round tube design meets ergonomic grip standards, increasing hand contact area by approximately 20%. The surface conducts heat evenly, maintaining a comfortable grip even in fluctuating temperatures. The pull resistance is stable and linear, suitable for extended use and preventing hand fatigue.

Shopping Mall Main Entrance

Glass door pull handles are used in all-glass doors at the main entrances of large shopping malls. Entrances are densely populated and frequently opened and closed. Glass door handles need to provide a stable and comfortable grip throughout the business day, facilitating entry and exit. They are typically installed with a double-sided pull mechanism, working in conjunction with the access control system's glass door clamps, floor springs, or upper pulleys.

Office Building Elevator Lobby

Glass door pull handles are used in the glass partition doors of office building elevator lobby antechambers. Crowds gather here, creating short periods of congestion during peak hours in the morning and evening. The handles need to provide a clear force point, allowing users to open and close the door naturally while walking, minimizing sway caused by sudden tugs or sideways pulls. Once installed, they coordinate with the floor guides and door closer timing, ensuring a more controlled door return, reducing noise and collision risks in the elevator lobby.

Hotel Guest Hallway

Glass door pull handles are used in the glass partition doors separating the hallways and entrances of star-rated hotels. The hotel emphasizes quietness and quality. The handle's design, integrated with lighting, metal baseboards, and other elements, significantly enhances the hallway's visual appeal. When staff push linen carts, the round handle provides a stable grip, allowing for single-handed door opening and controlled door return speed to avoid impact with walls or luggage.

Medical Clean Areas

Glass Door Pull Handles are installed in glass doors in hospital outpatient surgical areas, laboratory departments, and laboratory corridors. Clean areas emphasize cleanability and chemical resistance. The handle's continuous surface, free of complex textures, facilitates disinfection with alcohol or quaternary ammonium salts, reducing bacterial adhesion. Medical staff maintain a stable grip even while wearing gloves, allowing them to quickly pass through the door after opening, minimizing dwell time.

Deep Cleaning

In addition to regular weekly cleaning, we recommend a monthly deep cleaning. First, remove dust and fingerprints from the surface with a damp cloth in warm water. Then, carefully wipe along the metal grain with a neutral detergent. Use a soft-bristled brush to clean stubborn stains in the gaps between the door frame and the handle. Then, wipe with clean water to remove any residual detergent. Finally, wipe thoroughly dry with a dry cloth.

Surface Care

Carry out surface care for the handle every three months. Choose a silicone-free stainless steel oil or microcrystalline wax, apply a thin layer to the surface, and polish evenly to create a breathable, hydrophobic film that effectively reduces the direct adhesion of moisture, salt, and stains. In highly corrosive areas, such as coastal areas or near swimming pools, we recommend reducing this frequency to monthly.

Tightening Recheck

To prevent minor movement or thread loosening due to long-term use, we recommend a quarterly tightening recheck. Inspect the internal and external connecting bolts, decorative covers, and the area around the glass opening for signs of movement. If loose, tighten each one with the appropriate hexagon socket head to the specified torque.

Scratch Treatment

If minor scratches or abrasions appear on the surface, address them as soon as possible. Use a 1000-1500 grit stainless steel repair cloth to gently rub along the original brushing direction until the scratch blends into the surrounding grain. Degrease with alcohol and apply a layer of conditioning oil to seal.

Usage Precautions

Good handling habits can significantly extend the lifespan of the handle. It's recommended to avoid prolonged handling with wet hands. After showering or cleaning, wipe off any water droplets and detergent residue. During renovations or maintenance work, apply a protective film to the handles to prevent adhesion of paint, adhesives, or grout.
