Door Panels: The door panels are mostly made of rigid panels filled with polyurethane foam in the middle. For example, the products of Beijing Xuri Huanzhao New Building Materials Co., Ltd. The common panel width is 220mm, the effective width is 200mm, and the overall panel thickness is 40mm.
Tracks: They adopt aluminum alloy combined tracks and double spiral turbo guide rails. They operate quietly, smoothly, and have strong load-bearing capacity, which can reduce the contact, friction, and wear between the door panels and connecting parts.
Door Curtains: They have a split assembly structure design, including thickened color steel door panels, stainless steel door panels, and aluminum alloy door panels and other materials. They are equipped with multi-layer sealing strips, sound-absorbing load-bearing hinges, polyurethane guide wheels and other components.
Fast Opening and Closing: The opening speed is usually between 0.6 - 2.0 meters per second or even higher. For example, the products of Shenzhen Jie De Automatic Door Co., Ltd. can reach an opening speed of 1.2m/s - 5.88m/s, enabling quick opening and closing so that vehicles don't need to wait for a long time when entering or exiting.
Thermal Insulation and Energy Saving: The polyurethane foam filling material in the middle of the door panels has good thermal insulation performance. For example, the aluminum alloy rolling shutter doors for three-dimensional garages can effectively isolate the temperature difference between the garage and the outside world, reduce the risk of ice formation in the vehicle, and lower energy consumption.
Wind Resistance and Anti-theft: They have strong wind resistance, generally able to withstand level 12 winds. The structure is sturdy and can effectively resist the invasion of strong winds. Meanwhile, the materials are solid and durable, possessing certain anti-theft functions.
Good Sealing Performance: The bottom of the door curtain is equipped with an air barrier cloth made of U-shaped PVC base cloth or a rubber sealing strip. Both sides of the door frame are also equipped with sealing brushes or rubber sealing strips, which can effectively prevent dust, insects, and have sound insulation effects.
Safe and Reliable: They are equipped with multiple safety devices, such as infrared safety protection (light curtain), anti-collision posts, bottom safety protection edges, safety airbags, etc. When obstacles or people are detected, the door body can automatically stop or rebound to prevent clamping or collision accidents.
It can be equipped with a variety of opening methods, such as buttons, radars, geomagnetic loops, wireless remote controls, card swiping, fingerprint recognition, photoelectric sensors, pull ropes, ETC, AB door interlocking and combinations, meeting the usage needs of different users.
In addition to being suitable for underground garages, they are also widely used in logistics, cold chain, food, electronics, textiles, pharmaceuticals, printing, chemical industry, shopping malls and other places where there are high requirements for the frequency of opening and closing and certain requirements for environmental control.
The main components are composed of programmable controllers from Omron, Siemens, Mitsubishi, Holip, Delta and other brands and inverters from Yaskawa, Mitsubishi, Holip, Siemens, Delta and other brands. Or step motor controllers and servo controllers are used, and positioning is achieved through incremental rotary encoders, mechanical travel limits and encoders. It can be connected to a variety of auxiliary equipment and linked with other equipment.
It can choose servo motors, motors from Sino-Japanese joint venture AEW and German brand SEW and other brand motors. The power supply voltage is 220V or 380V, and the power is matched according to the size of the door body. There are balance springs inside both side door posts, which keep balance with the weight of the door panels, reducing the load on the motor operation and making the operation smooth.
Various Colors: The frames and door panels have a variety of colors to choose from, such as the original colors of aluminum alloy and stainless steel, dark gray, Emei gray, and "local tyrant gold" champagne color, etc., which can match the appearance of buildings.
Beautiful Windows: Some door models are equipped with windows made of polycarbonate sheets. The double-layer structure design not only ensures the thermal insulation effect but also maintains good transparency and aesthetics.
