Small Stainless Steel Single Action Spring Hinge-DDSS035

Core Components & Functional Design

1. Spring-Loaded Mechanism

• The hinge houses a coiled torsion spring within its barrel, which stores mechanical energy when the door is opened.

• Upon release, the spring’s tension generates a controlled force to smoothly return the door to its closed position, ensuring consistent latching.

2. Multi-Directional Adjustment System

• Vertical Adjustment (Up/Down): Equipped with threaded screws or pins, the hinge allows fine-tuning of the door panel’s height relative to the frame. This compensates for floor irregularities or sagging over time.

• Horizontal Adjustment (Left/Right): Lateral screws enable lateral shifting of the hinge leaf, ensuring perfect alignment between the door and frame. This prevents binding, air leakage, or uneven gaps.

• Plate Thickness Adaptability: Some models feature removable spacers or adjustable plates to accommodate doors of varying thicknesses (e.g., 35mm to 50mm), enhancing versatility.

3. Tension Control & Customization

• Many spring hinges include an adjustable tension screw, allowing users to modify the spring’s resistance based on the door’s weight (lightweight interior doors vs. heavy fire-rated doors).

• This adjustability ensures optimal closing speed, preventing slamming or incomplete closure.

Key Advantages

• Automatic Closure: Eliminates manual effort, reducing wear on door frames and improving energy efficiency (e.g., in climate-controlled rooms).

• Enhanced Safety: Critical for fire doors, which must remain closed to comply with building codes and prevent smoke/flame spread.

• Noise Reduction: Prevents doors from slamming, making it suitable for quiet environments like hospitals, libraries, or hotels.

• Longevity & Low Maintenance: Constructed from durable materials (e.g., stainless steel, zinc alloy), these hinges resist corrosion and require minimal upkeep.

Applications

Spring hinges are widely used in scenarios demanding controlled access and reliability:

• Commercial Buildings: Office entry doors, conference room partitions, and restroom stalls.

• Residential Spaces: Screen doors, pantry/laundry room doors, and garage side doors.

• Public Facilities: Fire doors in schools, theaters, and hospitals; kitchen doors in restaurants.

• High-Moisture Areas: Pool enclosures, marine applications, and industrial facilities.

Technical Specifications (Example)

• Material: 304/316 stainless steel (corrosion-resistant).

• Spring Type: Torsion spring with adjustable tension.

• Adjustment Range: ±3mm vertical/horizontal.

• Door Weight Capacity: Up to 60kg (depending on model).

Why Choose a Spring Hinge?
