The Stainless Door Stop is a mechanical buffering hardware device installed on the floor or wall, providing stable resistance and shock absorption when the door opens to a predetermined angle, preventing the door panel from directly impacting walls, glass, or other fixed structures. Made primarily of SUS304/SUS316 stainless steel, and incorporating a high-density rubber buffer ring structure, this product effectively reduces the impact force during door opening through physical energy absorption. Compared to ordinary plastic or magnetic door stops, this type of stainless steel door stop offers higher structural strength and durability, maintaining stable functionality even under frequent use.

1. Robust and Impact-Resistant

The Stainless Door Stop features a one-piece stainless steel machined structure with a main body wall thickness of ≥2.0mm. Under experimental conditions, it can withstand instantaneous door impact forces of ≥60N without structural deformation. The double-layer rubber buffer rings have a hardness controlled at Shore A 70±5, absorbing over 65% of kinetic energy upon contact, effectively reducing door panel rebound and concentrated stress on the floor, improving overall safety and stability.

2. Corrosion-Resistant Structure

The main body material is available in SUS304 or SUS316. Under standard salt spray test conditions, SUS304 can withstand 48 hours without significant corrosion, while SUS316 can last for over 96 hours.  It is suitable for environments with long-term humidity exceeding 70%RH. The stainless steel and rubber are fixed using a compression method, avoiding adhesive aging and detachment problems, ensuring long-term corrosion resistance and structural integrity.

3. Precise Dimensions

The standard Stainless Steel Door Stop has a height of 38mm, a top diameter of Φ39mm, and a base diameter of Φ32mm, with a dimensional tolerance controlled within ±0.3mm, ensuring precise alignment with the bottom edge of the door or wall. This proportion is compatible with most interior doors and glass door bottom gaps, preventing buffer failure due to insufficient height and avoiding tripping hazards due to excessive height.

4. Quiet Buffering

The double-layer rubber rings utilize a segmented buffering design; the first layer absorbs the initial impact, and the second layer delays energy dissipation, reducing door contact noise by approximately 40%. Under actual test conditions, the door opening collision sound level can be reduced from 55dB to around 33dB, significantly improving the acoustic environment in residential or public spaces.

5. Reliable Installation

The Stainless Door Stop uses a central screw fixing structure at the bottom.  M6 stainless steel expansion screws are recommended, providing a single-point tensile strength of ≥800N. It can be installed on concrete, tile, or wood surfaces. An installation depth of ≥30mm is recommended to ensure that it does not loosen or shift under high-frequency use, meeting the requirements for long-term stable use.

1. Residential Entrance Doors

In residential entrance door systems, the Stainless Door Stop prevents the door panel from hitting the wall or shoe cabinet structure when opened at a wide angle. For a typical 35–45kg entrance door, this door stop can reliably withstand repeated opening impacts, reducing long-term stress fatigue on the door hinges and frame, and extending the overall lifespan of the door system.

2. Bedroom Doors

Bedroom doors are typically opened frequently and the space is relatively compact. The door stop limits the maximum opening angle of the door, preventing the doorknob from directly colliding with the wall. Its cushioning and noise reduction properties significantly reduce noise when opening or closing the door at night, improving living comfort.

3. Bathroom Spaces

In bathroom environments, where humidity is consistently above 80% RH, ordinary carbon steel or plastic door stops are prone to aging and failure. Stainless steel door stops, with their corrosion resistance, can operate stably for extended periods, preventing loosening of fixing screws or structural damage due to rust, thus enhancing overall safety.

4. Hotel Guest Rooms

Hotel guest room doors are opened more than 30 times a day on average, requiring a door stop with high durability. The stainless steel structure maintains its appearance and functionality under high-frequency use, while the consistent metallic texture contributes to the overall interior design style.

5. Commercial Offices

Office doors are mostly standard wooden or glass doors. The door stop effectively prevents the door from hitting glass partitions or wall decorations. Its compact size does not hinder passage, and its stable stopping ability makes it suitable for continuous use over long periods.

Q: Is this stainless steel door stop floor-mounted or wall-mounted?

A: This product features a standard floor-mounted design, fixed to the floor base with a single screw at the bottom. The screw length and fixing method can be adjusted for wall or door frame installation depending on project requirements, but the installation plan and load direction must be confirmed before placing an order.

Q: Are there any requirements for the floor material during installation?

A: Suitable for concrete, tile, and solid wood bases. For tiled floors, it is recommended to drill a hole before fixing to prevent tile cracking. The installation depth should be at least 30mm to ensure tensile and impact strength.

Q: Can the rubber buffer ring be replaced?

A: The rubber ring is removable and can be replaced after prolonged use. The standard rubber hardness is Shore A 70±5. If special buffering requirements exist, different hardness specifications can be customized during the OEM stage.

Q: Do you support custom sizes or surface treatments?

A: We support OEM customization services, including height, diameter, and surface treatment. Surface finishes include brushed or polished options, and colors or details can be adjusted to match the overall door hardware system according to project requirements.

Q: Will the stainless steel door stop affect walking safety?

A: The standard height of 38mm has passed conventional walking safety tests and will not significantly obstruct normal walking. The edges are rounded to reduce the risk of foot contact, making it suitable for residential and public spaces.
