This Floor Door Stop is a floor-mounted doorstop device primarily used to prevent doors from colliding with walls or furniture due to excessive opening. It features a compact design (25×25mm) with a stainless steel body and rubber bumper, offering a clean, square appearance. Its stable base effectively absorbs impact, protecting the door and floor from damage. Available in satin or polished finishes, it boasts a refined texture and complements modern architecture, residential, and commercial space décor.

High Strength and Pressure Resistance

This floor door stop is made of SUS304 or SUS316 stainless steel, with tensile strengths of 520 MPa and 580 MPa respectively. This high-strength material ensures the doorstop will not deform or loosen under frequent impacts.

Effective Cushioning

The top rubber pad is 4 mm thick and made of highly elastic synthetic rubber with a Shore hardness of 70±3A. It quickly absorbs energy and disperses pressure upon impact. Tests show that its cushioning and shock absorption rate is as high as 82%, effectively preventing direct hard contact between the door and the doorstop, reducing impact noise and surface wear.

Corrosion and Rust Resistance

The product surface undergoes a fine satin or polishing treatment, combined with the inherent oxidation resistance of stainless steel, allowing it to maintain its shine and rust-free appearance even after 48 hours of salt spray testing. It maintains its metallic texture even in humid or near-coastal environments, making it suitable for outdoor and high-humidity spaces.

Secure Installation

The Floor Door Stop uses concealed floor bolts for fixing, with mounting hole accuracy controlled within ±0.1 mm to ensure a tight fit with the floor. After installation, the product can withstand a torque of 50 N·m without loosening. The finished surface is flat with no visible screws, balancing aesthetics and practicality.

Precision Craftsmanship

The overall design is square, with standard dimensions of 25×25mm and a height of 20mm or 30mm. Precision CNC machining ensures smooth edges and a high degree of fit. The surface roughness reaches Ra≤0.2 μm, providing a smooth, non-sharp feel.

Residential Door Control

Floor door stops are commonly used in homes for bedroom, kitchen, or balcony doors to prevent them from impacting walls due to wind or accidental operation. Tests show they absorb approximately 80% of impact energy, effectively reducing the risk of cracking in wooden doors and walls, and improving home safety and noise reduction.

Commercial Venues

In offices, meeting rooms, or hotels, floor door stops control the maximum opening angle of doors, preventing glass or heavy doors from damaging floor finishes. Their square design and metallic finish harmonize with modern commercial spaces, serving both practical and decorative purposes.

Public Buildings

Widely used in high-traffic areas such as hospitals, schools, and train stations. Their stainless steel structure is wear-resistant and impact-resistant, tested to withstand 500 opening and closing impacts daily, maintaining its original shape even after a year of continuous use. This reduces maintenance costs and enhances facility durability.

High-End Projects

In villas, apartments, and high-end renovation projects, floor door stops are used as metal detailing elements, creating a unified visual effect with baseboards and door hardware. Its mirrored or brushed finish makes it a subtle highlight of the floor decoration, combining functional and aesthetic value.

1. What flooring materials are suitable for the Floor Door Stop?

It can be installed on tile, marble, wood flooring, and concrete floors. It is recommended to use expansion bolts for fixing to ensure stability. Ensure the floor is level and dry before installation.

2. What is the difference between SUS304 and SUS316?

SUS304 is suitable for general indoor environments, while SUS316 contains 2-3% molybdenum, which enhances its resistance to chloride corrosion and is more suitable for coastal, humid, or chemical environments.

3. How should the doorstop height be selected?

If the door gap is small (less than 25mm), the 20mm model is recommended; if the door is thicker or the gap is larger, the 30mm model can be selected to ensure cushioning effect and aesthetic harmony.

4. Will the product surface scratch?

The surface undergoes precision grinding and hardening treatment, resulting in excellent wear resistance. According to friction test results, its surface hardness reaches HRB 85, resisting daily friction and impact from shoe soles, and is not easily scratched.

5. Is it easy to install?

The installation process is simple, requiring only drilling holes for fixing. Accessories include screws and expansion tubes; it's ready to use after installation. Generally, one person can complete the installation within 5–8 minutes.
