We made a parking lot available on the first floor. The folding door was installed there, separating the space from the indoor parking lot and the outer parking lot.
Like the car center, parking lots also have a lot of traffic, so we built folding doors for the car center.​

Folding doors for car centers are a little different from conventional folding doors. The weight of the vehicle is unbearable with a regular folding door lower rail.
It's highly damaged. The lower rails exposed to the surface are larger than normal (wing type) to distribute the heavy weight, allowing any vehicle to pass smoothly and without jams.
​
It has the same purpose as a regular folding door, but it has different materials, increasing durability and reducing breakage rates.
