Steel Acoustic Door Steel Doors Steel Swing Door Insulation

Steel acoustic door is a popular category of all acoustic doors. As we can see from the name, steel acoustic door is made of steel. There is no wood.

1. Made of steel with paint.
2. With threshold by default.
3. Painted finish with simple colors.
4. Higher acoustic performance than acoustic wooden door.
5. Higher cost than acoustic wooden door.

Most of the energy radiated from the indoor noise to the door leaf is reflected by the door leaf, part of the energy is transmitted to the door through the internal structure of the acoustic door leaf, and some energy is directly transmitted to the outside of the door through the gap between the door leaf and the door frame. Therefore, the design of the door leaf structure and the gap of the steel acoustical door directly affect the sound insulation of the door. It can be known by the mass rule that the material density increases by 1 time and the sound insulation increases by 6dB. The disadvantage is that the weight of the door leaf is greatly increased, and the door hinge load is increased.

Acoustic Steel Door Specifications

Door frame specifications: 910x2100mm, or customize
Door thickness: 60mm
Acoustic performance: Rw/STC steel acoustic door 40 dB
Hardware accessories: self-drop seal for bottom of the door, the strip for door side, door locks, door closers (optional)

Application

Industry: generator room, refrigeration room, steel swing door insulation, pump room and so on.
Business: recording studio, piano practicing room, KTV room, conference room and so on.
Family: home theater, HIFI audio-visual room, study room, piano room and so on.

Although steel acoustic door can be used in the all the above projects, due to its simple color and threshold, it’s more often used in industry applications.

HuiAcoustics Steel Acoustic Door Advantages

1. Seamless processing: There is no visible light transmission gaps after installation.
2. 3D hinge: The bearing hinge is used and seamlessly processed for acoustic steel doors.
3. High quality door handle: It is made of high quality stainless steel handle and the sound is difficult to pass through.
4. High precision: After closing the soundproofing door, the gap between the door leaf and the door frame is 3mm, which is much smaller than the 8mm of ordinary door.
