Where Buildings Blossom With Confidence
Maximum Aperture Clearance
Traditional sliding doors are constrained by overlapping track limitations, with even multi-track systems only opening up to 67% of the opening area. This folding door system adopts a multi-sash linked articulated structure, where all sashes can be fully folded and stacked against one or both side walls when opened, achieving seamless indoor-outdoor floor continuity and unprecedented spatial openness.
90° Post-Free Corner Panoramic Breakthrough
Breaking the conventional limitation that building corners must have physical load-bearing columns, the system is specially equipped with a 90° post-free corner folding solution. Bi-directional folding sashes meet and close seamlessly at the 90° corner, leaving the building corner completely open when pushed - designed for modern coastal villas and luxury restaurants to create panoramic vistas.
150kg Per Sash & 3.5m Height Load Capacity
Maximum sash production height supports up to 3500mm (3.5 meters), maximum single sash width reaches 1500mm, with 150KG load capacity per sash. Relying on heavy-duty top load-bearing rails and bottom high-load pulley dual engagement, eliminating sagging deformation and sliding jamming of multiple large-sized glass doors under long-term suspended load.
700Pa Rainstorm Watertight Defense
Targeting the common weakness of water leakage through multiple vertical joints in traditional folding doors, the system adopts continuous premium sealing gaskets for tight wrapping and embedded buckle locking mechanism. Tested whole-window watertight performance reaches 700Pa (National Standard Class 6), wind pressure resistance reaches 5.0kPa (National Standard Class 9), completely blocking coastal typhoon rainwater intrusion.
ES 82 / System anatomy
Deconstructing the ES 82 platform: 82mm frame depths, 74mm sash profiles, and INVISO concealed hinges secure operational longevity across heavy glass spans.
82mm frame depth and 74mm sash thickness construct a high bending-resistance foundation: Outer frame structural depth 82mm, sash profile depth reaches 74mm, with ultra-high moment of inertia in cross-section. Main load-bearing profile wall thickness reaches 2.0mm - 2.5mm, ensuring sashes do not bend or tremble under strong gust wind at 3.5m extreme height conditions.

Main load-bearing profile wall thickness reaches 2.0mm - 2.5mm, ensuring sashes do not bend or tremble under strong gust wind at 3.5m extreme height conditions.
55mm visible sash face width, configured with external heavy-duty hinges, extremely high mechanical load-bearing shear resistance, specifically designed for high-frequency commercial public passages.
Specially designed edition, adopting fully concealed invisible hinge mechanism, sash facade visible face compressed to an ultra-narrow 36mm, no exposed hinges visible on the exterior when closed, with pure and minimalist lines.
Meeting accessibility passage and ultra-high watertightness requirements:
Extremely low threshold height, balancing indoor smooth passage convenience with basic water blocking, specifically for indoor partitions or covered eave areas without rain exposure risk.
Meeting accessibility passage and ultra-high watertightness requirements:
Standard stepped threshold construction, with reliable continuous sealing gasket contact and stepped drainage performance, suitable for most terrace and garden access ways.
Meeting accessibility passage and ultra-high watertightness requirements:
Bottom track fully embedded within the floor finishing layer, achieving zero height difference between indoor and outdoor floors for completely accessible passage, while constructing a 700Pa stringent watertight defense line through built-in deep drainage channels.
Configured with dedicated top pulley guidance and bottom pulley load-bearing modules, paired with profile-embedded buckle lock. When closed, the buckle mechanism engages for flush locking, with light and flexible opening/closing and no operation noise.
