Due to the influence of covid 19, many self-employed people are still suffering financially. A growing number of self-employed people are taking advantage of this period when the number of visitors has decreased to proceed with interior construction or construction that has been delayed before. Therefore, there are more and more inquiries and construction of the folding door of the mall.​

This construction site is the folding door and the hinge door construction site outside the store on the first floor of the shopping mall located in Seodaemun-gu, Seoul. If a regular glass fix window is built, it is a fixed fix window that needs to be passed through one door, so if many people come in, go out, and employees move at the same time, it can cause difficulties.​

In that case, all folding doors are opened and closed to provide smooth access and free access in addition to the entrance.Also, the hinge installed with the folding door can be easily accessed using a separate door, the hinge, without having to go through the folding door.

A hinge door is a door that rotates 180 degrees that serves as a door for people to enter and exit. It is compatible with the folding door, so it is possible to open and close the folding door and the door as a whole, so safety is also improved.
