Comparison Between Industrial Lift Door And Roller Shutter

1、 Structure
(1) Industrial liftgate can be installed along the ceiling and wall rails to make reasonable use of space when the door body is running, which overcomes the shortcoming that Roller shutter can only use fixed installation space, and improves the space utilization rate in the workshop.
(2) The door body of the industrial lift door adopts a horizontal split foldable connection, making the door easier to repair and replace. At the same time, small doors and windows can be opened, and the use of interlocking devices to open small doors facilitates personnel passage and ensures the safety of the gate operation, fully reflecting the convenience of the passage and saving energy.
(3) The bearing type operation is adopted for the door body of industrial lift gate, which not only overcomes the disadvantage of loud operation noise of Roller shutter, but also makes the gate run more smoothly.
2、 Features:
Characteristics of Industrial Liftgate:
1. It is composed of two layers of galvanized sheet, with surface spray treatment (ordinary panel), oxidation resistance, and high-density expanded polyurethane foam filled between the two steel plates, which is heat and sound insulation, and has strong mechanical resistance.
2. The spring polyurethane seal ensures a compact and durable appearance of the entire door body.
3. Surface treatment: classic powder spraying process, which is characterized by strong durability, anti-aging, corrosion resistance, fade resistance, easy maintenance, and lasting as new.
Features of Roller shutter:
1. Anti push device to prevent forced prying of the door body and prevent theft.
2. (Optional) The humanized design of automatic rebound when encountering obstacles prevents the door body from falling and colliding with vehicles, allowing people or vehicles to pass smoothly. The door body is sturdy and can be equipped with (optional automatic alarm device) and anti push device to prevent forced prying of the door body, continuous alarm, and security theft prevention.
3. According to the different characteristics of the building, three different installation methods can be selected: interior, exterior, and interior. After opening, the rolling shutter is rolled up on the upper part of the door, saving internal space in the garage and not bringing debris such as mud, rain, and snow into the garage. The appearance is beautiful and fashionable.
3、 Material
(1) The door body of industrial liftgate is filled with double layer hot cut galvanized steel plate with polyurethane foam, which improves the flame retardancy compared with ordinary Roller shutter, and greatly reduces the cost compared with fireproof Roller shutter.
(2) . Compared with the Roller shutter motor, the industrial liftgate motor has many functions, which can be connected to remote control, radar, geomagnetic ring and other electrical switches; It can be connected to protective devices such as infrared and airbag safety edges.
4、 Opening method
The opening method of industrial lift doors can be achieved according to the requirements of the site:
1. Electric opening: It can be controlled by a button and has a manual emergency unlocking device, which is the most commonly used.
2. Manual opening: Use a manual hoist to open (commonly used)
3. Geomagnetic ring: Especially suitable for places where the entry and exit of hairpin trucks and forklifts need to be closed in a timely manner.
The opening mode of Roller shutter is:
1. Manual roller shutter. By utilizing the torsion spring on the central axis of the roller shutter to balance the force, the purpose of manually pulling the roller shutter is achieved.
2. Electric roller shutter. Use a dedicated motor to drive the central axis of the roller shutter to rotate, reaching the roller shutter switch. When it reaches the upper and lower limits set by the motor, it automatically stops. Special motors for Roller shutter include: external rolling door machine, Australian rolling door machine, tubular rolling door machine, fireproof rolling door machine, inorganic double curtain rolling door machine, fast door machine, etc.
