Lever Lever door handles are door opening components consisting of lever-type handles on both sides, suitable for doors that require operation from both the inside and outside. They achieve smooth opening and closing through a mechanical lever structure, providing a stable and effortless feel for the user, while also featuring excellent ergonomic curves for a natural and comfortable grip. In practical use, this product emphasizes smooth and comfortable operation, ensuring a fluid and reliable experience for users in both residential and public areas.

Lever Lever Door Handles Parameters:

Lever Lever Door Handles Features:

1. Robust Structural Design

Lever Door Handles utilize a high-precision casting structure, with support components, hinges, and internal spring systems machined using data-driven processes. This ensures that the clearance between components is controlled within approximately 0.1mm. Compared to ordinary handles, its durability is improved by about 30%.

2. Strong Corrosion Resistance

The handle body is made of SS304 or SS316 stainless steel. SS316 offers approximately 40% better resistance to chloride ion corrosion, maintaining structural stability even in humid environments, environments with frequent disinfectant use, or environments with large temperature fluctuations.

3. Reliable Rebound System

The internal spring assembly is made of high-carbon steel or manganese steel, maintaining over 85% of its standard spring force after 20,000 uses. Compared to ordinary springs, it is more fatigue-resistant and maintains a consistent rebound speed even during rapid opening and closing actions.

4. Stable Installation Compatibility

The handle structure is designed according to international standards, making it compatible with most wooden doors, metal doors, and fire door systems on the market. The mounting hole spacing, square shaft dimensions, and matching screws are all standardized, ensuring an installation success rate of over 98%.

5. Durable Surface Coating

Surface treatments include PVD, brushing, and polishing. The PVD surface layer achieves a hardness of HV1600–1800, resisting daily friction, cleaning agent contact, and high-frequency pressure. After abrasion testing, the surface showed no significant scratches after 400 cycles of 300g pressure, ensuring the handle maintains its metallic texture and luster over long-term use.

Lever Lever Door Handles Application:

1. School Classrooms and Teaching Areas

Lever Door Handles are ideal for schools because classroom, office, and public area doors are opened and closed frequently, requiring stability and durability. Their lever-type structure allows students and teachers to open and close doors quickly without jamming.

2. Public Restroom Doors

In public restrooms, handles need not only smooth operation but also superior cleaning adaptability. Lever Door Handles' stainless steel surface can withstand repeated wiping with cleaning agents of varying strengths while maintaining its integrity and color.

3. Medical Institution Doors

Hospital examination rooms, treatment rooms, and offices require doors with high hygiene and corrosion resistance. Lever Door Handles' SS316 material maintains stable performance even after prolonged contact with alcohol and disinfectants and has high antimicrobial compatibility, making it an ideal choice for medical environments.

4. Commercial Retail Store Interior Doors

In clothing stores, shopping malls, and back-office areas of retail stores, door handles need to meet high usage frequency and stable performance requirements. These handles maintain a smooth and easy-to-use feel during rapid opening and closing, and will not loosen with repeated use. Their appearance also complements the modern décor of the store, creating a unified overall environment.

Lever Lever Door Handles FAQs:

Q: Can this handle be installed on existing door locks?

A: Most standard door locks are compatible with Lever Door Handles, but you need to confirm the square shaft dimensions, screw hole positions, and door thickness. If the door structure is custom-made or older, installation can be achieved by replacing the fittings. It is recommended to measure the relevant dimensions before ordering to avoid incompatibility issues.

Q: Is regular maintenance required?

A: The handle itself does not require complex maintenance; simply check the screws for looseness and keep the surface clean. If the installation environment is humid, it is recommended to perform a tightening check every 6 months to ensure structural stability. Avoid using strong acid or alkaline cleaners to prolong the surface's lifespan.

Q: Can children operate it easily?

A: The lever mechanism itself requires relatively low downward force, and most children can open and close the door smoothly. Its rotational torque is designed within a reasonable range, maintaining both safety and ease of operation. For use in children's rooms or educational institutions, a lock cylinder combination with higher security can be selected.

Q: Will frequent use cause it to loosen?

A: When correctly installed, the handle structure can withstand prolonged, high-frequency use. If slight loosening occurs after several years of use, it's usually due to natural displacement of the fixing screws, which can be easily corrected by tightening them. The internal structure of the handle has undergone durability testing and will not affect normal use due to loosening.

Q: Can I choose different surface colors?

A: We support various surface treatments, such as brushed silver, mirror silver, PVD black titanium, gold, and bronze, which can be matched to different door styles. All surface colors have passed corrosion resistance tests and will remain unfaded for a long time during daily use.
