1. Good airtightness. When the hinged door was first designed, it was the original shape of the door. At that time, it was required to effectively prevent wind, sand, dust, or other impurities from entering the house, so the sealing performance was absolutely high. Swing doors are protected by a layer of glue on the periphery than other doors, which can effectively isolate them when in use. 2. High security. The safety performance of swing doors is higher than that of other categories. The swing door can be installed with a lock when in use, and for ordinary families, the swing door is made of relatively hard materials, which is very convenient and safe to use. 3. Easy to use. Whether it is temperature insulation or daily maintenance, it is more convenient and durable.
