Aluminum folding door is a type of door that achieves a “folding and closing” opening method through multiple door leaves connected in series by hinges, combined with tracks and hardware components. Its core advantage lies in the fact that the door leaves can be folded and retracted to one or both sides when opened, significantly saving occupied space. At the same time, it combines the characteristics of transparency and aesthetics, flexible adaptability, as well as durability and practicality. Widely used in homes, commercial premises, offices and public spaces, it is an ideal choice for optimizing large-span door openings and realizing flexible space conversion.
