The most comprehensive introduction to industrial sectional steel doors knowledge
Compared with garage doors, industrial sectional steel doors have higher requirements for opening speed, thermal insulation, sound insulation, sealing, and wind resistance. It is suitable for industries such as large warehouses, logistics industries, medicine, food, factories and mining enterprises that have high requirements for opening speed, thermal insulation, sound insulation, sealing, wind resistance, etc. Especially in places where the door opening is large and it is inconvenient to install a ground door. It can be opened conveniently and quickly.
Characteristics of industrial sectional steel doors
- Door panel material
The door panel is made of thickened double-layer galvanized color steel plate. And the interior is made of high-density polyurethane foam filling. It has the advantages of heat insulation, sound insulation, heat preservation, etc., and is suitable for large warehouse and factory doors.
According to the building structure design. The sectional door opens vertically upwards and hangs flat on the inside of the wall above the door opening, without occupying any indoor space. Taking full advantage of rising vertically and not occupying both sides of the door opening. The door opening space is released to a large extent.
The double-layer galvanized steel plate combined with the polyurethane layer . The embossed surface design can make the door panel durable, easy to clean, beautiful and elegant, and enhance the corporate image.
- Noise isolation
Low-noise opening, the galvanized pulley base is equipped with adjustable ball bearings and wear-resistant rubber wheels to ensure silent opening and closing of the door.
- Wind resistance
When the door body reaches a certain width, external reinforcement ribs are designed to ensure its strength. Tested by European standards, it can withstand instantaneous wind force of level 10.
- Air tightness
The top, bottom and both sides of the door panels are equipped with high-quality rubber sealing strips. There are also reliable seals between the door panels to ensure that the door body is not corroded. Sealing strips are installed all around, and the air tightness is very good.
- Safety devices
Anti-fall device and airbag (optional) to prevent the door body from falling or the bottom of the door colliding with an obstacle, the door will automatically stop or run in reverse to avoid accidents; anti-wire rope breakage device and torsion spring breakage safety device. Prevent harm to people or things。
- Pass gate
Opening the small door is convenient for daily travel. The small door and the main door cannot be opened at the same time. The small door and the main door are equipped with non-contact safety electric shock. The main door can only be opened when the small door is closed.
How to lift industrial sectional steel doors
The design principle of industrial sectional overhead doors is to install the track as close to the inside of the building as possible, thus saving a large amount of internal space in the building. Depending on the size and shape of your building, sectional doors can be designed to be installed in different ways. The selection of the lifting method of industrial Overhead sectional doors can be based on the following basic conditions. Door opening size, door opening upper space, door opening side space and door opening depth, etc.
According to the actual conditions of the building site and the owner’s space usage requirements. Industrial Overhead sectional doors can achieve the following lifting methods to maximize the rational use of space.
- Standard Lifting
Standard 90° turn, lower bottom space, minimum distance from ceiling to door opening 500mm.
- Improve Lifting
The most widely used, the distance between the ceiling and the door opening must be greater than 500mm.
- Vertical Lifting
The door body can freely slide up and down vertically, and the distance between the ceiling and the door opening must be greater than the door opening height.
What are the control methods for the automatic opening of the sliding door?
- Remote control
It is suitable for access doors where forklifts and other vehicles and people frequently enter and exit. Press the remote control to open the door.
- Radar sensing
It is suitable for access doors that frequently enter and exit forklifts and other vehicles and personnel. It can be opened and closed automatically without human operation.
- Manual button
It is suitable for passage doors where people come in and out frequently. When people come in and out, they can open the door by pressing the button.
- Rope switch
It is suitable for access doors where forklifts and other vehicles and people frequently enter and exit. The door can be opened by stretching out the hand and pulling the rope.
- Geomagnetic induction
When the control box control handle reaches the automatic transmission position. If a metal object passes through the geomagnetic induction coil sensing area, such as a vehicle or other equipment, or a person pushes or pulls a metal car, the door will open automatically. The sensitivity intensity of the geomagnetic ring sensor is adjustable.
- Linkage interlock
It is mostly used for workshop doors and passage doors in factory buildings with high cleanliness requirements. The door can be opened fully automatically by connecting to an automatic trigger sensor device. Such as radar, geomagnetic ring sensor, photoelectric induction, etc.
The industrial sectional overhead door slides upward under the indoor ceiling after being started. It is lifted by a small-power motor and does not occupy indoor space, which can greatly improve the utilization of indoor space. It is widely used in industrial plants, warehousing warehouses, logistics unloading ports, factory entrances, workshops, warehouses and other building entrances.
