In the past, stores/stores that needed a wide entrance installed a shutter door that opened and closed up to make a wide entrance. However, due to the nature of the shutter door, it is made of opaque steel, so visitors often recognize that when the shutter door is closed, it is not open outside. So once it's open, it's open until the end of business hours.

To compensate for these shortcomings, the folding door, which is a left-right opening/closing method, can be easily opened and closed when necessary, can block changes in outside temperature and weather, and can reduce costs by preventing loss of cooling/heating energy.

Folzen Korea's folding door, which passed the nation's first "International Accredited Testing Agency" test structure, watertightness, and airtightness, has high insulation, soundproofing, and windproof effects, so it does not cause damage to other buildings or companies.
