AI Technical Summary
The vibrations generated by existing metal awnings during rain or hail can amplify the sound, causing noise problems and affecting normal work and life.
The design incorporates a combination of noise-reducing ceiling panels, sound-absorbing ceilings, vibration-damping components, and drainage structures, including metal composite ceiling panels, honeycomb structure panels, sound-absorbing pads, and water-blocking baffles. This reduces noise through sound insulation, sound absorption, vibration damping, and rapid drainage.
Significantly reduces rain impact and drainage noise, especially suppressing mid-to-high frequency sounds, improving structural stability and wind resistance, preventing water accumulation and overload, and maintaining long-term performance and aesthetics.
