Perforated aluminum plate (also commonly referred to as punched aluminum plate due to its use of punching technology) refers to a rectangular material with a uniform thickness and a cross-section obtained by mechanical pressure processing (shearing or sawing) of pure aluminum or aluminum alloy materials. Beautiful in appearance, elegant in color, and good in decorative effect, it can be used to improve sound quality conditions in public buildings such as hotels, restaurants, cinemas, and broadcasting rooms, as well as in high-end civil buildings. It can also be used as a noise reduction measure in various workshops, factories, civil defense basements, etc. It has become a popular product in the decoration market in recent years.
Perforated aluminum plate is a new product that reduces noise and has decorative effects. The specific performance characteristics are as follows: 1. Lightweight material, high temperature resistance, corrosion resistance, fire resistance, moisture resistance, shock resistance, good chemical stability, beautiful appearance, elegant color, strong three-dimensional sense, and good decorative effect. 2. The application of lightweight, stable, and perforated lightweight aluminum plates reduces the weight of the material, which is very beneficial for the lightweight design of structural load-bearing and members. 3. The facade is simple and vivid, with patterns formed through regular perforations, making the simple facade shape rich, lively and vivid. 4. Perforated aluminum plates greatly reduce the shading coefficient of glass, playing a good role in shading, thereby reducing the impact of solar radiation on indoor areas, blocking direct sunlight, preventing glare, and making indoor illumination distribution uniform, which is conducive to normal visual work. 5. The process is simple, and installation and maintenance are convenient.
Here are various types of perforated aluminum plates. Meet the needs of different construction engineering fields and consumer decoration needs. At present, perforated aluminum plates are classified according to their alloy composition and thickness. According to the alloy composition, it can be divided into high-purity aluminum plate, pure aluminum plate, alloy aluminum plate, composite aluminum plate, welded plate, and aluminum clad aluminum plate. Divided by thickness: thin plate (0.15mm-2.0mm), conventional plate (2.0mm-6.0mm), medium plate (6.0mm-25.0mm), thick plate (25mm-200mm), five ribbed aluminum plate, and ultra thick plate (>200mm). According to the type of punching technology, it can be divided into: patterned punching mesh, formed punching mesh, heavy-duty punching mesh, ultra-thin punching mesh, microporous punching mesh, wire cut punching mesh, laser punching mesh, etc. Punching holes according to hole specifications mainly include rectangular holes, square holes, diamond holes, circular holes, elongated holes, hexagonal holes, cross holes, triangular holes, long waist holes, plum blossom holes, fish scale holes, patterned holes, octagonal mesh, herringbone holes, pentagonal star holes, irregular holes, bulging holes, irregular holes, louver holes, etc. Perforation rate refers to the percentage of the total area of perforated holes within the perforation area range. (1) The most common aperture is 6mm with a spacing of 15mm. (2) According to current mechanical equipment, the highest perforation rate can reach around 65%, and the perforation plate size is required to be within the range of 1500 * 3000. If it exceeds this range, perforation requires secondary positioning. (3) The higher the perforation rate of perforated aluminum plates, the greater the impact on the flatness of the formed aluminum plates, and the inspection standards should be lower than the corresponding regulations for normal aluminum plates. The price of perforated panels is mainly determined by their alloy composition, aluminum plate thickness, and hole pattern. Generally speaking, the higher the content of precious metals in alloys, the higher the price; The thicker the thickness, the higher the price; The more complex the hole, the higher the price.
