Comparison Of Industrial Lifting Doors And Rolling Shutter Doors

I. Structure
(1) The industrial lifting door can install the track along the ceiling and wall to make reasonable use of space when the door body is running, overcoming the shortcomings of the rolling shutter door that can only use a fixed installation space and improving the space utilization rate inside the workshop.
(2) The door body of the industrial lifting door adopts a horizontal split folding type connection, making the door easier to repair and replace. At the same time, small doors and small Windows can be opened, and the use of interlocking devices to open small doors facilitates the passage of personnel and ensures the safety of the operation of the gate, fully reflects the convenience of the channel and saves energy.
(3) The door body of the industrial lifting door adopts the bearing operation, which not only overcomes the shortcomings of the rolling shutter door running loud, but also makes the door run more smoothly.
Ii. Features:
Industrial lifting door features:
1, there are two layers of galvanized sheet, surface spray treatment (ordinary panel), anti-oxidation, between the two steel plate filled with high-density expanded polyurethane foam, heat insulation, sound insulation, strong mechanical resistance.
2, spring polyurethane seal makes the whole door body appearance compact structure, strong and durable.
3, surface treatment: classic powder spraying process, which is characterized by strong durability, anti-aging, anti-corrosion, do not fade, easy maintenance, long as new.
Rolling shutter door product features:
1, anti-push device, to prevent forced means to lever the door body, security and anti-theft.
2. (Optional) The humanized design of automatic rebound in the event of obstacles prevents the collision of the car when the door body falls, so that people or vehicles can pass smoothly. The door body is strong, and can be equipped with (optional automatic alarm device) and anti-push device to prevent forced means to pry the door body, continuous alarm, security and anti-theft.
3. According to the different characteristics of the building, you can choose three different installation methods: inside, outside and inside. After opening, the curtain is rolled in the upper part of the door body, saving the interior space of the garage, and will not bring dirt, rain, snow and other debris into the garage.
Third, material
(1) The door body of the industrial lifting door is filled with double-layer hot 锓 galvanized steel plate with polyurethane foam inside, which improves the flame retardant compared with the ordinary rolling shutter door and greatly reduces the cost compared with the fireproof rolling shutter door.
(2) Compared with the rolling shutter door motor, the industrial lifting door motor has added a lot of functions, and can be connected to external remote control, radar, geomagnetic ring and other electrical switches; Can be connected to infrared, air bag safety edge and other protective devices.
4. Opening method
Industrial lifting door opening mode Industrial lifting door can be opened in the following ways according to the requirements of the site:
1, electric open: can be opened by press and button control, with manual emergency unlock device, the most common use.
2, manual opening: the use of manual hoist open (commonly used)
3, geomagnetic ring: for the hairpin and forklift in and out of the need for timely closure of the place is especially suitable.
The opening mode of the rolling shutter door is:
1. Roll the curtain manually. The torsion spring on the central axis of the roller curtain balances the force to achieve the purpose of pulling the roller curtain manually.
2. Electric roller blinds. The special motor is used to drive the central shaft of the rolling shutter to rotate, and the rolling shutter switch is reached. When it is rotated to the upper and lower limit set by the motor, it automatically stops. Special motors for rolling shutter doors are: external rolling door machine, Australian rolling door machine, tubular rolling door machine, fire rolling door machine, inorganic double curtain rolling door machine, fast door machine.
