Stainless Steel 4 Inch Modern Flush Hinge for Offices Bifold Doors-DDSS026-4x3x2.5

First Point: Technical Specifications

 Model and Dimensions: The product model is DDSS026, with standard dimensions of 4 inches (length) × 3 inches (width) × 2.5 mm (thickness). These specifications strictly adhere to industry-standard dimensions, ensuring compatibility with mainstream door panel profiles and thicknesses. Its compact design achieves structural integrity while delivering a visually lightweight appearance, making it ideal for modern minimalist office furniture and interior doors.

Material and Surface Finish: The main body is crafted from 304 stainless steel, containing ≥18% chromium and ≥8% nickel for superior corrosion resistance. The surface undergoes a refined satin-brushed finish, offering a smooth tactile experience while effectively concealing minor scratches from daily use, maintaining lasting aesthetics. This finish aligns with universal hardware design standards and complements diverse interior styles.

Applications and Load Capacity: Designed for commercial and residential settings, it excels in office cubicles, hotel bathrooms, retail storage rooms, and residential built-in wardrobe doors. Mechanical testing confirms each hinge assembly reliably supports door weights of 25-35 kg, meeting the needs of most interior folding and swing doors, providing a reliable basis for project selection.

Second Point: Product Features 

Space Optimization & Aesthetic Design: The standout feature of this Flush Hinge is its recessed installation method. Unlike traditional hinges, it eliminates the need for deep mortises in both door panels and frames. Once installed, the door panel aligns perfectly flush with the frame, achieving seamless integration. This not only creates an exceptionally clean and elegant visual effect but, more importantly, completely eliminates potential space obstructions or clothing snags caused by protruding hinges. It is particularly suitable for narrow passageways, densely arranged cabinetry, and modern office environments pursuing an ultra-minimalist aesthetic.

High Strength and Durable Structure: We utilize 2.5mm thick stainless steel plate, precision-formed through stamping processes, ensuring the robustness of the hinge leaf. Compared to cost-reduced alternatives using thinner sheets, our Flush Hinge resists deformation during frequent operation—especially in bidirectional folding doors—extending its lifespan. The tightly fitted pin ensures stable, wobble-free door operation for reliable, long-term performance.

Superior Corrosion Resistance & Low Maintenance: The 304 stainless steel construction offers superior rust resistance compared to standard carbon steel plated hinges, withstanding moisture in the air and cleaning agents. The satin stainless steel surface is smooth and non-porous, resisting dust and grease buildup. Daily maintenance requires only a soft cloth wipe to restore cleanliness. This makes the Flush Hinge equally effective in environments requiring high hygiene standards, such as hotel and hospital lockers or food preparation areas.

Third point: Application Scenarios 

Office Space Partitions and Cabinet Doors: In modern open-plan office spaces, this Flush Hinge is the perfect choice for glass partitions in manager offices, filing cabinets, and storage cabinet doors in break rooms. Its sleek design ensures clean, crisp lines when the cabinet is closed, seamlessly blending with the modern aesthetic of office furniture. For frequently used cabinet doors in print rooms or archives, its robust structure guarantees long-term reliability. Opting for this Flush Hinge enhances the professional and tidy image of the entire office environment while reducing maintenance costs associated with hinge damage.

Hotel and Commercial Bathrooms & Room Doors: This Flush Hinge demonstrates significant advantages in applications such as hotel guest rooms, public restrooms in shopping malls, or partition doors in dining areas. Its stainless steel material resists moisture and prevents rust. The flush-mounted design eliminates external protrusions, enhancing safety in public spaces and making cleaning more convenient and efficient. For hotel mini-bar cabinet doors or bathroom storage cabinets, it enables seamless opening and closing, improving spatial coherence and guest experience.

High-end Residential Wardrobes and Storage Rooms: For housing projects that prioritize space utilization and aesthetics, this hinge is the ideal accessory for custom wardrobes, walk-in dressing rooms, and storage room folding doors. It allows the door panels to align seamlessly with the cabinet body, maximizing every inch of space, making it particularly suitable for small户型 designs. Its quiet and smooth opening/closing features ensure a tranquil living environment, while its durable quality guarantees long-lasting performance even with frequent household use.

Retail Store Display and Storage System: In boutiques, showrooms, or bookstores, this Flush Hinge can be used for folding doors in the back warehouse, display cabinets in the front area, or movable partition walls. Its unobtrusive design ensures that customers' attention is fully focused on the products without being distracted by hardware components. For retail environments requiring flexible space layout adjustments, its reliable performance ensures the partition system can withstand repeated assembly, disassembly, and use.
