It was conducted with a wide space measurement and a high-load upper rail and a car center-type lower rail that can easily handle the heavy weight of the vehicle as the height is increased.

Due to the height of the raised folding door, there may be a small shaking, so we added one middle bar to make it more durable. Also, it is more safe to make one glass that is longer as it has been raised and divided into two glass sheets.When I added one middle bar, it became the point of the folding door, and it was created as a more luxurious entrance.

Previously, shutter doors, which are the top and bottom modes of operation, used to be installed and used in places where wide entrances were needed. Although the wide entrance is owned, it cannot be closed during work because it had to be continued in an open working space after opening, causing great inconvenience to the operator depending on the weather and temperature changes.

It is also difficult to install and use such a high place. Since you can open and close the folding door anytime after installation, it is a pleasant environment where you can work on cold and hot days without any inconvenience.
