Aluminum Round Hole Perforated Metal Mesh (Dustproof & Sound-Absorbing Type) is a functional metal mesh sheet made of high-quality aluminum plate or aluminum alloy plate, with uniformly distributed round holes processed by precision CNC stamping technology. Relying on the advantages of aluminum material such as light weight, corrosion resistance and easy processing, combined with the reasonable arrangement of round holes and open area ratio design, the product achieves a perfect balance of three core functions: dustproof, sound absorption and ventilation, and is the preferred product for dustproof and noise reduction in industrial, civil and commercial scenarios.
In terms of dustproof performance, by precisely controlling the aperture size and open area ratio, the product can effectively block dust and particles of different particle sizes from entering the interior of equipment or spaces, and at the same time, it will not hinder air circulation, avoiding equipment failures and stuffy environments caused by dust accumulation and blockage, which is suitable for use in scenarios with different dust concentrations.
In terms of sound absorption and noise reduction, the uniformly distributed round holes form a porous structure. When sound waves pass through the mesh sheet, they will reflect, scatter and lose energy in the holes, thereby effectively weakening medium and high-frequency noise. The noise reduction effect can be further improved when used with sound-absorbing cotton. It is widely used for sound insulation treatment around noise sources such as fans, air conditioning units, machine rooms, workshops, office buildings and residential areas.
The product is made of pure aluminum or aluminum alloy. Compared with other metal perforated mesh, it is lighter in weight, easy to carry, cut and install. It can be bent, welded and equipped with borders according to actual needs, adapting to various installation forms such as equipment enclosures, ventilation hoods, sound insulation covers, wall sound-absorbing panels and ceilings. After surface treatment such as anodizing and painting, it not only improves corrosion resistance and oxidation resistance, prolongs service life, but also can match the decorative style of different scenarios, achieving the unity of practicality and aesthetics.
