Aluminum Bifold Doors
Folding door systems that open entire walls to the outside.
Aluminum Bifold Doors Built for Wide Openings
Aluminum bifold doors from WANJIA Hiseng give builders and architects a practical way to connect indoor rooms with patios, decks, and backyards. The panels fold to one or both sides, so the full opening stays clear for foot traffic, furniture, and fresh air.
We manufacture four aluminum folding door series: 68, 75, 80, and 88. Each series can be configured with different panel counts, sizes, and opening directions. The 88 series is ENERGY STAR certified and uses 2.0 mm aluminum profiles with 2.2 mm local reinforcement.
For North American projects, we ship from our factory in Foshan, China. Lead time is usually 25-30 business days, and we provide installation videos and remote guidance after delivery.
