With more than 90% of the openings and closures, you can use a wide space that feels like an expansion by opening the folding door, and on the other hand, you can separate the space and use it as a veranda and two living rooms. The most significant part of the folding door construction process is frame fixing.

It should be more precise, it is a meticulous and detailed process, so construction should be carried out safely without distortion or damage to many folding door drives over a long period of time.
