SS316 Door Hinges Antirust Non-Mortise Butterfly Flush Hinge with Mounting Screws-DDSS026-4x3.5x3

Dimensions and Model: The standard model is DD026, measuring 4 inches (length) x 3.5 inches (width) x 3.0 millimetres (thickness). This specification has been precisely calculated to achieve an optimal balance between load-bearing strength and visual harmony. A single hinge assembly can withstand a static load of up to 50 kilograms, meeting the load requirements of the vast majority of interior doors.

Design and Compatibility: Featuring a non-mortise butterfly hinge design, it ensures uniform clearance between door leaf and frame post-installation. The surface undergoes a refined satin stainless steel finish, combining aesthetic appeal with fingerprint-resistant properties. The product comes standard with high-quality 304 stainless steel mounting screws, perfectly matched to the hinge's pre-drilled holes for secure and straightforward installation.

Superior Corrosion Resistance: The core advantage of this Stainless Steel Flush Hinge lies in its SS316 material. Compared to common SS304 or electroplated carbon steel products, the added molybdenum provides exceptional resistance to chloride-induced pitting corrosion (e.g., from sea salt or disinfectants). This translates to extended service life in environments like hotels, coastal residences, or healthcare facilities, significantly reducing maintenance and replacement costs associated with hinge corrosion.

Slot-free installation design: The unique non-slotted butterfly structure is another standout feature. Traditional mortise hinges require time-consuming and labour-intensive cutting of complex recesses into both door and frame. Our Stainless Steel Flush Hinge eliminates this step. Installation simply involves securing the two hinge leaves to the door and frame respectively, greatly enhancing efficiency and reducing labour costs – particularly suited for large-scale projects.

Structural Durability and Superior Load-Bearing: Despite its slim profile, mechanical strength is ensured through 3.0mm thickened plates and a precision bearing structure. The hinge pivot undergoes specialised processing for smooth rotation and wear resistance. Rigorous testing confirms this Stainless Steel Flush Hinge withstands high-frequency operation, exceeding industry durability standards to provide enduring, stable support for door panels.

Hotel Room Interior Doors and Wardrobes: Within hospitality projects, this Stainless Steel Flush Hinge is the ideal solution for guest room doors, bathroom doors, and built-in wardrobes. Its SS316 material resists corrosion from cleaning chemicals, maintaining long-lasting aesthetics. The flush-mounted design eliminates the risk of clothing snagging on protruding hinges, ensuring tidiness and safety within guest rooms. Its silent operation further enhances the guest experience.

High-End Residential Interior Doors: For residential projects prioritising quality of life, this hinge suits all interior doors, such as bedrooms and studies. Its no-cutout installation minimises damage to door panels and frames, making it particularly suitable for highly customised solid wood doors. The elegant satin finish seamlessly integrates with diverse contemporary interior styles, highlighting attention to detail.

Medical Office & Storage Cabinets: In hospitals, clinics, and other healthcare settings, hygiene and durability are paramount. This Stainless Steel Flush Hinge features a smooth, non-porous SS316 surface that facilitates easy cleaning and disinfection while resisting corrosion from various sanitising agents. Its robust construction withstands high-frequency use in medical environments, ensuring consistent door functionality.

Commercial office partitions and furniture: Suitable for office partition doors, filing cabinets, and storage units. The non-slotted design facilitates rapid installation and subsequent adjustments, significantly enhancing fit-out and maintenance efficiency. The hinge's corrosion resistance and extended lifespan reduce long-term property maintenance costs, offering a cost-effective solution for modern commercial spaces.

Installation Guidelines

Step One: Positioning and Marking

First, place the door leaf into the door frame and adjust its position using shims. Clip the two leaves of this Stainless Steel Flush Hinge into the edge of the door leaf and the inner side of the door frame respectively, ensuring they lie completely flush. Using a pencil or scriber, precisely mark the screw hole positions on both the door and frame through the installation holes in the hinge.

Step Two: Pre-drilling and Fixing: Remove the hinge. Using a drill bit slightly smaller than the supplied screws, pre-drill holes at the marked positions. The pre-drilled depth should be slightly longer than the screw length to prevent wood splitting and facilitate easier screw insertion. Subsequently, reposition the Stainless Steel Flush Hinge leaves. Using the supplied screwdriver or power drill, tighten the provided Mounting Screws one by one, ensuring the hinge lies flush against the timber surface.

Step Three: Door Hanging and Adjustment: Lift the door leaf, aligning the hinge leaves mounted on the door with those on the frame. Insert the connecting pin (for split designs) or snap the hinge plates together (for integrated butterfly designs). Verify the door opens and closes smoothly with even gaps. If necessary, adjust the screw tension to fine-tune the door's position, completing the installation.
