This aluminum alloy folding door uses an aviation-grade aluminum frame, which is stronger and has a longer service life than ordinary aluminum. The surface of the door frame is sprayed with Dutch Interpon powder, which is evenly applied to the profile, making the surface smooth and enhancing its weather resistance and corrosion resistance. Flexible opening and closing, the door leaf is connected by a hinge and can be folded open, saving space and suitable for wide opening areas. The large glass panel provides sufficient lighting and a wide field of vision. The three-sealed structure design builds a quiet life that is warm in winter and cool in summer. The rib-shaped cavity insulation strip isolates high temperature and severe cold, provides a comfortable living environment, and saves energy and reduces emissions.
