Industrial lift doors are generally used in factories, and the shutter doors are used in addition to factories, shopping malls, etc. What is the difference between the two? Let's take a look.
First, the structure
(1) The industrial lifting door can be installed along the ceiling and the wall to make reasonable use of the space when the door body is running, which overcomes the shortcomings that the rolling door can only use a fixed installation space, and improves the space utilization inside the workshop.
(2) The door of the industrial lift door is connected by a lateral split folding type, which makes 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 gates, fully embodies the convenience of the passage and saves energy.
(3) The door of the industrial lifting door adopts the bearing type operation, which not only overcomes the shortcomings of the running noise of the rolling door, but also makes the door run more smoothly.
Second, the material
(1) The door of the industrial lifting door adopts double-layer hot-dip galvanized steel plate. The internal polyurethane foam filling improves the flame retardancy compared with the ordinary rolling door, and the cost is greatly reduced compared with the fire shutter door.
(2) Compared with the rolling door motor, the industrial lifting door motor has many functions, such as an external switch, a radar, a geomagnetic ring and other electrical switches; it can be connected with infrared, airbag safety and other protection devices.
