High corrosion resistance: Made of Satin stainless steel, its corrosion resistance has been verified by ASTM B117 salt spray test, and it can maintain excellent anti-rust ability in harsh environments. This material can withstand more than 240 hours of corrosion environment in the salt spray test, ensuring that the door handle can remain smooth and new when used for a long time in coastal areas with high humidity and high salt or industrial environments.
Ergonomic optimization: The curvature and gripping area of the handle are carefully designed to conform to ergonomic principles. The length and diameter ratio of the handle allows the user's wrist to bend naturally when applying force, reducing hand fatigue caused by long-term use. For example, the handle diameter is 19-20 mm and the length is 130-140 mm. This size combination allows the user's fingers to naturally wrap around the handle when holding it, providing a comfortable use experience.
Versatile material adaptation: In addition to standard Satin stainless steel, a variety of surface treatment options such as Gold Plated, Gun Grey and Matte Black are also available. Each color has passed strict quality inspections to ensure that its wear resistance and corrosion resistance meet industry standards. For example, the Gold Plated surface adhesion test results meet the ASTM B571 standard, and after 500 friction tests, the gold coating on the surface showed no obvious peeling or wear.
Precise installation and adaptation: The disc base is designed with self-aligning screw holes, which simplifies the installation process. The base diameter and the door hole diameter are matched with an accuracy of ±0.5 mm, ensuring that the door handle can be accurately installed on the door. For example, when the base diameter is 50 mm and it is adapted to the standard door hole of 70-75 mm, the depth of the mounting screw can be adjusted to achieve a tight fit between the door handle and the door surface, avoiding looseness or shaking.
High impact strength: The lever part of the handle is made of solid stainless steel and is processed by cold drawing process with a tensile strength of 550-700 MPa. When subjected to repeated opening and closing forces, the handle deformation rate is less than 0.1%, ensuring stable performance under frequent use. For example, in a simulated daily home use scenario, the door handle opens and closes 10 times per minute. After 1,000 consecutive tests, the swing angle deviation of the handle is still less than 1°.
Silent operation performance: The connection between the handle and the base adopts a precision bearing design with a friction coefficient of less than 0.05. When opening and closing the door, the handle rotates smoothly and the noise is less than 30 decibels, ensuring that there will be no harsh metal collision sound in a quiet indoor environment. For example, when used on a bedroom door, the user will not disturb others' rest due to noise when opening and closing the door at night.
Excellent thermal stability: The thermal expansion coefficient of the material is as low as 17×10⁻⁶ /°C, and the dimensional change rate of the door handle is less than 0.02% when used in a temperature range of -20°C to 80°C. This thermal stability allows the door handle to maintain normal opening and closing functions in extremely cold or hot environments, and will not cause jamming or loosening due to thermal expansion and contraction.
Solid mechanical connection: The connection between the handle and the base is precision machined to ensure that the connection accuracy reaches ±0.05 mm. This high-precision mechanical connection prevents the handle from loosening or shaking during long-term use, thus increasing the overall service life of the door handle. For example, under a pulling force of 50 N, the connection between the handle and the base does not move or deform, ensuring the reliability of the door handle under high-intensity use.
Interior doors: Round Rose Door Handle is suitable for wooden doors or composite doors in indoor spaces such as bedrooms, living rooms, and study rooms. Its visual effect of Satin stainless steel material complements the wooden floors or modern furniture in the room, providing an elegant visual experience. For example, installing a door handle of size 20 (length 140 mm, height 65 mm, diameter 19 mm) on a bedroom door can meet the needs of daily entry and exit, and its simple design style will not conflict with the interior decoration style.
Bathroom door: Considering the moisture and corrosion resistance of Satin stainless steel, this door handle is very suitable for installation on bathroom doors with high humidity. It can resist the erosion of water vapor and detergents, maintaining long-term gloss and functionality. For example, the door handle of size 21 (length 140 mm, height 65 mm, diameter 20 mm) has a larger diameter and length that provides users with a comfortable grip, ensuring easy operation in a slippery environment, and its material can resist the detergents frequently used in the bathroom, such as chlorine-containing disinfectants, ensuring the long-term performance of the door handle.
Commercial buildings: In commercial places such as office buildings and hotels, Round Rose Door Handle can be used for office doors, conference room doors or guest room doors. Its multiple color options can meet the decoration needs of different commercial places. For example, the door handle in Gold Plated color is installed on the guest room door of a luxury hotel, which can enhance the overall grade and luxury. According to the ASTM B117 salt spray test standard, the door handle of this material has no obvious corrosion on the surface after 240 hours of testing, ensuring durability under frequent use in commercial places.
Public buildings: In public buildings such as hospitals and schools, the Satin stainless steel material of Round Rose Door Handle is easy to clean and not easy to hide dirt, which meets the requirements of public health. Its self-aligning screw hole design simplifies the installation process, which is suitable for saving time and labor costs in large-scale installation. For example, installing a door handle of size 19 (length 130 mm, height 60 mm, diameter 16 mm) on a school classroom door can meet the daily needs of students entering and exiting. At the same time, its smaller size is suitable for children to hold and is easy to clean, meeting the hygiene standards of the school environment.
Retail venues: In retail venues such as shops and showrooms, the Round Rose Door Handle can be used for window doors, display area doors, etc. Its multiple color options (such as Gun Grey and Matte Black) can blend in with the decorative style of modern retail spaces. For example, the Matte Black door handle installed on the glass door of the showroom can add a sense of fashion to the overall space. According to industry standards, the lever operating force of the door handle should not exceed 10 N to ensure that customers can easily open the door. After testing, the door handle can smoothly open the door when a force of 8 N is applied, meeting the convenience requirements of retail venues.

If accidentally contacted, rinse the door handle immediately with clean water and wipe it dry with a dry cloth to reduce the risk of chemical corrosion on the stainless steel surface.
Check the screws regularly: Check the fixing screws of the door handle for looseness at regular intervals (recommended once a quarter). If the screws are found to be loose, they should be tightened with a screwdriver in time, but avoid over-tightening to avoid damaging the screws or the door handle base. For example, use a cross screwdriver to gently tighten the screws to ensure that the door handle is firmly fixed to the door, but the tightening torque should be controlled between 1.5-2 N·m to prevent the base from deforming or the screw from stripping.
Lubricant maintenance: For the rotating part of the lever handle, a small amount of lubricant can be used for maintenance regularly (once every six months). Choose silicone-based lubricants and avoid lubricants containing mineral oil to prevent oil residue and attract dust. For example, drip a drop of silicone-based lubricant on the shaft of the handle, and then repeatedly open and close the door handle several times to evenly distribute the lubricant, ensure smooth operation of the handle, and reduce friction and wear.
Prevent moisture intrusion: When using the door handle in a humid environment, care should be taken to prevent moisture from invading the internal structure of the door handle. Make sure the surface of the door handle is dry after each use. For example, in houses near the sea or in high humidity areas, door handles should be wiped with a dry cloth after each shower or wash to prevent moisture from adhering to the surface for a long time, causing the internal mechanism to rust or jam.
Repair scratches in time: If scratches or dents are accidentally caused on the door handle, they should be repaired in time. For minor scratches, stainless steel polish can be used for treatment, following the product instructions to restore the gloss of the surface. For example, for shallow scratches on the surface of Satin stainless steel, a special stainless steel polish can be used, apply the polish evenly to the scratch, and gently wipe with a soft cloth in concentric circles until the scratch disappears or becomes less noticeable, then rinse with clean water and wipe dry to maintain the overall beauty of the door handle.
