What is the difference between fire doors and rolling shutter doors
There are significant differences in structure and function between fireproof doors and rolling shutter doors (especially fireproof rolling shutter doors). The following is a detailed comparison between the two:
1、 Structure and Material
fire-proof door
Structure: Fire doors are usually fixed building components, with door frames and leaves made of fire-resistant materials that have strong fire resistance. It can be a single or double door, with a similar appearance to a regular door, but filled with fire-resistant materials inside.
Material: Fire doors are made of special materials with good fire resistance, such as wood, steel, stainless steel, etc.
Rolling shutter doors (especially fireproof rolling shutter doors)
Structure: Rolling shutter doors (especially fire-resistant rolling shutter doors) are a type of rolling barrier that can automatically sag, usually made of metal or special fire-resistant materials. The door is designed in a scroll style structure, which can be rolled up and stored during normal times. In the event of a fire, it can quickly slide down to form effective isolation.
Material: Fireproof rolling shutter doors are usually made of special fire-resistant materials, such as fire-resistant cloth, fire-resistant board, etc.
2、 Opening and closing mode

Opening and closing method: Fire doors have a similar opening method to ordinary doors, usually equipped with a fire door closer that remains closed during normal times. In the event of a fire, the door closer can automatically close the door. Most of them are manually opened or can be automatically closed, usually controlled by door closers or electromagnetic door locks in conjunction with fire alarm systems.
Rolling shutter doors (especially fireproof rolling shutter doors)
Opening and closing method: The roller shutter is controlled by an electric or manual device to lift and lower the door body. The fireproof rolling shutter door is rolled up at the top when not in operation, and once a fire occurs, it will automatically descend, forming a sealed fireproof barrier. The rolling shutter usually rises without affecting traffic, but automatically descends through electric or mechanical devices in case of a fire. Fireproof roller blinds usually do not automatically lift in emergency situations.
3、 Application scenarios and functions

Application scenario: Fire doors are mainly installed in evacuation routes, stairwells, computer rooms, and other places where smooth passage is required to prevent fires and smoke from entering specific areas, and to buy time for personnel evacuation. It is suitable for situations that often require opening and closing, such as passages between fire compartments.
Function: The main function of a fire door is to block the spread of flames and smoke, and protect the integrity of the passage. The fire rating is usually 0.5 hours, 1 hour, or 1.5 hours.
Rolling shutter doors (especially fireproof rolling shutter doors)
Application scenario: Fire resistant rolling shutter doors are mainly used in large openings or places where fixed fire doors are not suitable for installation, such as partitions in shopping malls, entrances and exits in underground garages, large warehouses, and other places.
Function: The main function of fireproof rolling shutter doors is to prevent the spread of flames and smoke. The fire rating can reach 2 hours or even longer, suitable for large-scale fire partitions. Due to its large coverage, it can effectively isolate larger fire areas.
4、 Maintenance and upkeep

Maintenance: Due to the frequent opening and closing of fire doors and their frequent use in daily life, it is necessary to regularly check whether the door closer, door lock, and other components are working properly to ensure their fire resistance performance.
Rolling shutter doors (especially fireproof rolling shutter doors)
Maintenance: The fireproof rolling shutter door is not frequently used and only starts in case of a fire. Therefore, the maintenance focus is on regular testing of the electric control system and automatic release device to ensure that they can respond quickly and function effectively in the event of a fire.
