I built a one-way construction with six pairs of doors.
One way is more efficient than two way in a less spacious space.​

If you install folding doors in an apartment, they don't carry a lot of weight like Cassenta, but even if there's no problem at first, the door may droop over time.​

Constructed from aluminum (AL-6N01) high alloy materials, which are primarily used in airplanes or ships, it is harder and more durable, with less damage and wear.
