Safe and stable | Quick installation | Easy operation |
This aluminum folding door system uses hidden flat handles with semi-automatic locks, replacing traditional flat handle locks. All models include stainless steel rollers with 304/420 housings and bearings treated for better corrosion resistance.
The hidden hinge aluminum folding door system features a new concealed hinge design that improves the overall sealing performance. High water and air tightness are achieved through staggered sealing strips at the top and bottom of the door panels, along with three sealing strips between the panels.
The exposed hinge aluminum folding doors share 80% of profiles and hardware with the hidden hinge system. A new train wheel roller design improves smooth folding and sliding. Special corner brackets replace aluminum edge trims to hide the rollers effectively
Innovative hardware design ensures safe and stable operation
Our designers prioritized safety and stability from the start. After studying many top folding door brands, they focused on simplicity, elegance, and performance. This resulted in the classic hidden flat handle lock combined with stainless steel train rollers, redefining the smooth aesthetic of aluminum folding doors.
Three sealing strips, perfectly tight seams.
Using a three-strip sealing design combined with track sealing, it enhances the thermal performance and airtightness of the aluminum folding doors.

Hinge sealing strips add an extra layer of protection.
All-around, gap-free sealing keeps wind and rain completely out of aluminum folding doors.
Automatic rebound latch design.
Innovative simplified structure replaces complex parts, easily made and installed within the profile cavity. Combined with flat handles, it simplifies locking—just pull the door panel after opening for automatic locking of smart aluminium bifold doors.
Anti-pinch design for enhanced safety.
Car-grade composite foam strips are installed in the gap between the door panel and mullion. Even if fingers enter the gap when the door closes, it effectively prevents accidental pinching on smart aluminium bifold doors.
Hidden roller design
Innovative spring-connected top rollers share the load with bottom rollers, working smoothly together.
This new design replaces traditional screw-mounted rollers with a simpler, safer, and more stable solution for smart aluminium bifold doors.
High-performance load-bearing roller set
Original train wheel structure is applied in the folding door roller set, adding a brush to clean the track and improve smooth folding and sliding. Using stainless steel 420 bearings and 304 stainless steel roller housings with surface passivation, the rollers’ rust and corrosion resistance is increased by over 90%, far surpassing similar products in smart aluminium bifold doors
Innovative water-blocking seal design
Clever water-blocking seal design adds an extra layer of protection to the luxury bifold doors, preventing rainwater from leaking inside through gaps.
Original design of roller set clearance groove
Using special corner brackets, a hidden clearance groove for the roller set is created after the door panel is angled at 45°, achieving higher sealing performance through simplified design in luxury bifold doors
Easy folding, full-width open space.
The CLS-73/65 series collapsible glass doors meet various application needs, breaking traditional folding limits. They create unique spatial designs while providing a comfortable indoor environment
