Product Advantages
Automatic Locking Door Panels
The door panels feature an automatic locking system that locks automatically when closed, without any extra operation. They can be easily opened with a simple press and push, offering greater convenience while improving safety and reducing potential risks.

Fully Concealed Profile Structure
The system adopts a fully concealed design. When the door is closed, all hardware components, including hinges and rollers, are hidden inside the profiles. This creates a cleaner appearance and gives the building a modern and elegant look.

Flexible Folding Configurations
A variety of folding configurations are available, including 220, 321, 330, 440, 422, 431, 550, 541, and 532. The door system can be customized according to different opening sizes and building layouts, making it suitable for a wide range of project requirements.

Column-Free 90° Corner Design
The innovative column-free 90° corner design allows the corner area to open completely, creating a wider view and a more open feeling. It also maximizes the available opening space and improves space utilization when the doors are folded away.
