Large Accordion Glass Door

Thickened cast metal exposed hinges are customized for oversized accordion glass panels with remarkable load-bearing capacity. The externally mounted hinge structure simplifies regular lubrication, overhaul and component replacement for long-term intensive usage in villas, restaurant facades and resort public areas. Each connecting joint adopts anti-loosening bolt configuration to avoid abnormal sway during frequent folding movement of large door leaves.

The integral aluminum frame is thickened as a whole to fit ultra-wide wall openings far beyond conventional household door sizes. Matched with multi-point stress dispersion layout, the frame can resist lateral wind pressure in high-rise buildings and coastal windy environments effectively. The frame outline keeps concise lines while satisfying the mechanical safety standard of large-span enclosure building components.

High-density polyurethane thermal strips are embedded inside the cavity of main profiles to cut off cold and heat conduction paths between inner and outer aluminum walls. The multilayer closed filling structure weakens cold air penetration in winter and heat invasion in summer, lowering the operating load of indoor air conditioning equipment for large open commercial and household spaces steadily all year round.

The whole set of door leaves can be orderly stacked on the side wall to release the whole wall access completely without occupying walking space. The matched silent pulley track buffers the sliding impact when folding and gathering massive glass panels. Standard safety anti-collision strips are equipped on every panel edge to prevent collision damage during manual push-and-pull operation.
