Three-Panel Folding Door Hinge
This three-fold hinge is specifically designed for aluminum alloy folding doors. Featuring a three-section split-pivot structure, it ensures smooth opening and closing with stable load-bearing capacity. Strictly compliant with the QB/T 5338-2018 standard for door & window accessories, it has undergone rigorous testing—including 100,000 opening and closing cycles and 500 hours of salt spray testing—demonstrating exceptional durability. It serves as the core load-bearing hinge component for narrow-frame folding doors and balcony partition folding doors.
Aluminum Alloy One-Piece Construction: Lightweight and High-Strength
The entire unit is die-cast from high-quality aluminum alloy, offering a lightweight design combined with excellent resistance to bending and compression. It maintains its shape and prevents sagging even under long-term load from the door panels. The internal pivot is equipped with a wear-resistant cushioning mechanism, ensuring quiet and smooth operation without jamming or unusual noises.
Surface finishes can be customized to meet customer needs, with options including fluorocarbon coating, anodizing, and sandblasting. These finishes complement various aluminum profile colors—such as black, white, and gold—and suit minimalist and light luxury interior design styles.
Three-section folding structure ensures flexible, jam-free operation
The three-fold segmented design supports coordinated movement of multiple folding door panels. When folded, the panels lie flat to save indoor space; the hinges feature moderate damping, making pushing, pulling, and folding effortless, and preventing the panels from swaying or slamming even in high winds.
The base features multiple sets of standard mounting holes, allowing for direct fastening to aluminum profiles without the need for complex grooving. This enables high-efficiency batch assembly at door and window manufacturers, along with simple installation and commissioning.
Multiple professional tests ensure long-term durability and weather resistance for outdoor use
1. 100,000-cycle fatigue test: Withstands 100,000 repeated folding cycles without loosening, cracking, or hinge play, meeting the demands of long-term, high-frequency use;
2. 500-hour neutral salt spray test: Excellent corrosion and rust resistance ensures long-term use on balconies and in humid outdoor environments without rusting or jamming;
The product complies with the QB/T 5338-2018 industry standard for door and window hardware, ensuring consistent quality and compliance. It is a reliable choice for both commercial projects and residential renovations.
Exclusively Designed for Aluminum Profile Folding Doors
Developed specifically for aluminum alloy folding doors, this product is compatible with interior partition folding doors, balcony sliding-folding doors, and commercial folding partitions. It can be paired with folding door locks and sliding handles to form a complete folding door and window hardware system, and fits a wide range of standard aluminum profile channels, offering high versatility.
