Punching Panels Work for Soundproof Walls
At present, perforated panels are widely used as sound insulation walls in airports, railway stations, highways, building construction and other fields. So what is the working principle of perforated panels as sound insulation walls?
The main purpose of perforated board sound absorption is to prevent sound reflection. Sound-absorbing perforated plates and sound-absorbing structures are divided into three categories according to the sound-absorbing mechanism: porous type, resonance type and composite type. According to the appearance and structure of the material, it can be divided into perforated mesh panels such as porous, perforated, thin wax, thin plate, and strong sound-absorbing structure. The sound absorption principle of the punching plate is the Helmholtz resonance sound absorption principle. It uses the special structure of the perforated plate to let the incident sound wave oscillate in the cavity with a small mouth and a large bottom.

Q: Can perforated sheet be plastic coated?
A: We don’t plastic coat perforated sheet, however we can perforate a plastic sheet.
Q: Why is perforated sheet protected with a thin layer of oil?
A: Lubricating oil is used to reduce the friction during the perforating process.
Q: Can perforated sheet be formed after perforating?
A: We can shear and form perforated sheet to any specification needed.
Q: What opening types are most common in perforated sheet?
A: Round, rectangular, and slotted perforated sheet are very popular options. See our decorative perforated sheet for more unique styles.
Q: Which perforated sheet materials are rust resistant?
A: Perforated aluminum, stainless steel, and galvanized perforated steel are the most rust resistant materials that we perforate.
Q: Why is perforated sheet commonly used?
A: Perforated sheet is used for a variety of applications because of the hole size options, percentage of open area, high strength-to-weight ratio, and aesthetic appeal.
Q: Can I choose the material type for my perforated metal sheet?
A: Yes, there are many material options for your perforated sheet order. Perforated steel comes in both stainless perforated steel and carbon perforated steel. You can also choose aluminum perforated sheet. If you need help deciding between perforated steel, perforated aluminum, and other material options, you can learn more in our Perforated Metal Catalog.
