In addition, the surface of the sound-absorbing panels is covered with the sound-absorbing paint surface layer to form a finish, thereby ensuring the integrity and neatness of the ceiling surface after the ceiling is installed.

[0016] 2. The inspection door at the inspection port can be removed as needed. After removal, the safety rope always remains connected. During maintenance, the inspection door is suspended by the safety rope. The inspection door will not fall and can also bear weight, which is convenient for maintenance personnel to install and disassemble the inspection door.

[0017] 3. General sound-absorbing panels are not suitable for frequent opening and closing as inspection doors. The inspection door of this application installs the sound-absorbing panel on the back panel and clamps it through the pressure strip to ensure the structural strength of the sound-absorbing panel, while ensuring the sound-absorbing effect at the inspection door and the integrity of the sound-absorbing effect of the entire ceiling system.
