Aluminum Bifold Doors Built for Wide Openings
Aluminum bifold doors replace a wall with a row of panels that fold to one side. WANJIA Hiseng manufactures these doors in four series: 68, 75, 80 and 88. Each series is made from extruded aluminum and can be configured for residential or commercial openings.
The 88 series is ENERGY STAR certified and uses 2.0 mm profiles with 2.2 mm local reinforcement. Sash widths range from 500 to 900 mm and heights from 1900 to 3000 mm. Standard glass is 5+27A+5 tempered insulated units.
The bottom sliding system can bear up to 400 KG. Hardware options include Kinlong, Hoppe, Cmech, VBH and G-U. We ship worldwide, with a focus on the North American market.
