Our company is one of the successful steel door manufacturers and suppliers of soundproof metal doors. The metal sound doors we offer are made of steel, single or double leaves, sliding horizontally or vertically. These provide excellent noise suppression in new or refurbished projects.
Acoustic Doors: – acoustic solid steel doors of the required size is filled with soundproofing material and a sound barrier. A neoprene gasket is placed between the frame and the door leaf to fill the gap between the door leaf and the frame. Contact us for soundproof door price.
STC Rating: 40 to 45
Hardware: Door handle, locked to close the door.

Custom size: door width: single leaf < 1000mm, double leaf < 2000mm; door height < 3000mm.
Combine professional manufacturing methods with rigorous processing procedures. The sound transmission level of the laboratory test is 45 dB.
Sound insulation design class:
The single solid steel door has a single steel door of 40-45dB.
The single acoustic door panel without a threshold is 35-40dB.
Double door steel sound door with a threshold of 35-40dB.
The double steel door without a threshold is 30-35dB.
1. Acoustic steel door adopts deep processing plate opening technology and automatic opening technology, CAD editing technology completes the whole door structure design, after deep processing plate opening technology, CNC bending forming, re-welding, high temperature baking paint and wood grain thermal transfer technology.
2. The door leaf and door frame are made of 1.5 mm thick galvanized steel.
3. The door frame is 103 mm wide by steel door manufacturer. The door frame is 45 mm thick. The casing has a width of 60 mm.
4. The door frame structure uses a double-layer magnetic sealing strip to slowly close the soundproof door.
5. When there is no threshold, use the automatic lifting seal to keep in close contact with the ground, soundproof, smokeproof, and mosquitoes cannot enter.
6. The soundproof interior door frame adopts a weighing hinge, and the angle and clearance range are controlled between 3 and 4 mm.
7. The door leaf adopts a T-shaped structure. Acoustic door cores: damped soundproof board, keel layer, sound absorbing and soundproof cotton. The thickness of the door leaf is 70mm.
8. If the sound insulation requirements are high, the steel door will be equipped with a threshold (threshold height of 45 mm).
