Core Features
· Space-Saving Folding Mechanism
The multi-panel design folds neatly to one side, creating an unobstructed, wide opening that connects indoor and outdoor spaces seamlessly. Precision hardware ensures the panels move smoothly without friction.

· Robust Aluminum Frame
Crafted from premium, corrosion-resistant aluminum alloy, the slim matte dark grey frame delivers exceptional durability and structural stability. It passed a 400-hour salt spray test, making it ideal for coastal or high-humidity environments. The flawless surface and uniform coating resist weathering and maintain a sleek appearance.

· Low-Iron Tempered Glass
High-clarity, impact-resistant low-iron tempered glass preserves your panoramic view while providing excellent thermal insulation and UV protection. It keeps interiors comfortable and shields furniture from sun damage.

· Precision Hardware with Long-Term Reliability
Heavy-duty hinges and ergonomic handles enable smooth, silent folding and locking. Rigorous testing confirms:
After 50,000 cycles of repeated use, the handle shows only minimal loosening (1.3mm lateral / 0.3mm vertical movement) and maintains full functionality.
Operating torque stays well under 4.0 N·m, ensuring effortless daily use.
The hardware withstands 600N tension and 25N·m torsion without damage or excessive deformation.

· Sleek Modern Aesthetic
The slim, matte dark grey profile complements contemporary architectural styles, enhancing both residential and commercial interiors. The frame’s uniform, corrosion-resistant finish remains free of defects, ensuring lasting visual appeal.

Important Usage Note
The handle features static color blocks to clearly indicate its operational status:

Red block: The door is in a locked/closed state. Do not attempt to move the door.

Green block: The door is in an unlocked/open-ready state and can be folded or maneuvered freely.

Always check the color block on the handle before operating the door to avoid damage to the hardware or frame.
