Applicability: According to the architectural structure design, the lifting door opens vertically upwards and is hung horizontally on the inner side of the wall above the door opening, without occupying any indoor space; Fully utilize the advantage of vertical ascent without occupying both sides of the door opening, and maximize the release of door opening space; 2. Appearance: Double layer galvanized steel plate with polyurethane layer, surface embossed design can make the door panel durable, easy to clean, beautiful and elegant, and enhance the corporate image; 3. Thermal insulation performance: Double layer steel plate reduces heat loss, with a high-density polyurethane insulation layer of 42kg/m3 sandwiched inside, providing thermal insulation effect; 4. Noise isolation: Low noise opening, galvanized pulley seat equipped with adjustable ball bearings and wear-resistant rubber wheels to ensure silent opening and closing of the door. 5. Wind resistance: When the door body reaches a certain width, external reinforcement ribs are designed to ensure its strength. Tested according to European standards, it can withstand instantaneous wind force of level 10. 6. Airtightness: The top, bottom, and both sides of the door panel are equipped with rubber sealing strips, and there is also a reliable seal between the door panels to ensure that the door body is not corroded. Sealing strips are installed around the perimeter to ensure airtightness; 7.
