1. According to the opening method
(1) Manual shutter. With the help of the balancing force of the torsion spring on the central shaft of the roller blind, the purpose of manually pulling the roller blind is achieved.
(2) Motorized roller shutters. Use a special motor to drive the central shaft of the roller blind to rotate to reach the roller blind switch, and stop automatically when the rotation reaches the upper and lower limits set by the motor. Special motors for rolling shutter doors include external rolling door machines, Australian-style rolling door machines, tubular rolling door machines, fireproof rolling door machines, inorganic double curtain rolling door machines, fast rolling door machines, etc.
2. According to the door material
Inorganic cloth rolling doors, mesh rolling doors, aluminum alloy rolling doors, crystal rolling doors, stainless steel rolling doors, color steel rolling doors, and wind-resistant rolling doors.
3. According to the installation form
There are two kinds in the wall and on the side of the wall (or called inside the hole and outside the hole).
4. According to the opening direction
There are two types of scrolling and side-scrolling.
5. According to the purpose
Ordinary rolling door, windproof rolling door, fireproof rolling door, fast rolling door, electric Australian style (silent) rolling door
6. According to the fire rating
According to GB14102 "General Technical Conditions for Steel Roller Blinds", ordinary steel roller blinds are divided into:
F1 grade, fire resistance time
F2 grade, fire resistance time
Composite steel roller shutters are divided into:
F3 grade, fire resistance time
F4 grade, fire resistance time
However, the national standard GB14102 does not require the fire resistance test to measure the temperature rise of the backfire surface for the fire resistance performance classification of steel rolling shutter doors and does not use the temperature rise of the backfire surface as a condition for judging the fire resistance time. Roller shutters, evaporative steam-mist steel roller shutters, etc., according to the requirements of the "high standard", when used as components for partition separation, the temperature rise of the back-fired surface must be used as the judgment condition for fire resistance. In order to distinguish the classification of roller shutters with fire resistance limits of the above two different judgment conditions, before the introduction of the national standard for the classification of roller shutters, the experts in the management of "High Regulations" suggested that: according to the national standard "Fire Resistance Test Methods for Doors and Roller Shutters" GB7633 conducts the fire resistance test and meets the requirements of various judgment conditions including the temperature rise of the backfire surface. The fire resistance limit ≥ 3.0h is called a super-grade roller shutter. It is a general term for those who do not take the temperature rise of the backfire surface as the judgment condition in the fire resistance test. Ordinary shutter door.
7. Specific classification introduction:
1). Traditional star plate rolling shutter door
It is also called the starboard gate. It is still the most common gate on the street. It makes the loudest opening noise. The manual one is laborious to open after a long time, and the electric one still makes a noise.
2). Aluminum alloy rolling shutter door
Compared with ordinary rolling doors, it has considerable advantages in terms of appearance, environmental protection, and safety. The aluminum alloy rolling door can be sprayed with various colors and patterns on its surface, and it can also be coated with uneven wood grain, sand grain, etc., which shows the noble temperament, obviously improves the grade of your berth, and makes you stand out among many berths.
The unique material and structural design of the aluminum alloy shutter door can effectively prevent strong light and ultraviolet radiation, and completely solve the greenhouse effect caused by sunlight in the room. It is suitable for various climate and weather changes and has long-term effects on the indoor environment. The protective effect, after testing, shows that the blocking rate of rolling shutter doors and windows to sunlight can reach 100%, and the blocking rate of temperature can reach more than 95%.
The aluminum alloy rolling shutter door has changed the inherent shortcomings of the traditional rolling shutter door, which is noisy. When opening or closing, there is only a sound like the wind blowing and falling leaves, giving you a comfortable feeling of opening the door. my country's rolling door suppliers can provide you with a complete set of high-quality rolling doors. (The aluminum alloy rolling shutter door was not designed for sealing at the beginning, but the sound-absorbing rubber strip was added to the curtain to improve the sealing performance, but it is still not sealed.) There are two kinds of aluminum alloy hollow extrusion profiles for the existing aluminum alloy rolling shutter door curtain. And aluminum alloy-filled polyurethane foam profiles, extruded curtains are superior to filled profiles in strength, hardness, production width, and protection performance, and the profiles of door body curtains can be freely selected according to different needs of customers.
3). Color steel rolling shutter door
● The door panels are made of color steel plates, aluminum alloy panels, or composite panels, and door panels of different thicknesses are selected according to the width of the door opening. Daylighting windows and door-in-doors (small doors) can be added as needed.
● A variety of panels and colors are available.
● The door panel can be equipped with various lighting windows, ventilation windows, and door-in-door (small door).
4). Grid rolling door
Even if the grid shutter door is closed, it will not give people the feeling of being stuffy in the box, and it is still breathable and light-emitting. And it can be used in conjunction with aluminum alloy rolling shutter doors to achieve ventilation and prevent peeping. {Note: If there is space in the middle of the door piece, it is called a grid rolling door, and some are called light-transmitting and ventilating rolling doors, light-transmitting and non-ventilating rolling doors (the name is too long), and mesh rolling doors (not all grid rolling doors have meshed as a whole. Yes, some have holes in the upper or middle).
5). Crystal rolling door
It is a representative of fashion in rolling shutter doors. Polycarbonate (pc bulletproof glue) is used to make engineering plastics to make curtains. Crystal rolling doors provide a fashionable look and feel for trendy shops such as fashion clothing, brand monopoly, and trendy mobile phones. It also has a certain waterproof and windproof effect, and the aluminum alloy connecting the rib strengthens the protective effect, and there are frosted, transparent, colored, and other specifications for the selection.
6). Stainless steel rolling door
It has beautiful color and luster, smooth, horizontal grain relief design, full of layers and three-dimensional sense; the surface of the door body is treated with baking varnish to make the door panel more durable; a variety of installation methods are available, and easy to install, fast construction speed and save construction period, if there is any damage, Can carry out single curtain replacement to save cost.
7). PVC rolling door
Also called fast rolling door, it is made of PV material. The running speed is very fast, reaching 0.6 m/s. It can be quickly isolated to ensure dust-free air quality in the workshop. It has many functions such as heat preservation, cold preservation, insect resistance, wind resistance, dust resistance, sound insulation, fire prevention, odor prevention, and lighting. It is widely used in food, chemical, textile, electronics, supermarkets, freezing, logistics, warehousing, and other places, can meet high-performance logistics and clean places, save energy, high-speed automatic shutdown, improve operating efficiency, create a better operating environment, and other advantages.
8). Fire shutter door
It is composed of curtain panels, roller bodies, guide rails, electric transmissions, and other parts. The curtain plate is made of 1.5-thickness cold-rolled strip steel rolled into a "C"-shaped plate overlapping and interlocking, which has the characteristics of good rigidity and excellent sealing performance. It can also adopt a steel "r-type series combination structure. It is also equipped with a temperature sensor, smoke sensor, light sensor alarm system, water curtain spray system, automatic alarm in case of fire, automatic spraying, automatic control of the door body, and fixed-point delay. It can be closed at any time so that people in the disaster-stricken area can be evacuated. The comprehensive fire protection performance of the whole system is remarkable.
