The secret of new building materials: How beautiful are perforated panels?

Perforated metal sheets have a history of nearly 150 years. With the development of technology, they have been widely used in architecture, landscape, and interior design. As a metal building material, perforated sheets are naturally avant-garde and are widely used in architecture, landscape, and indoor and outdoor decoration.

 

Perforated plate, as the name implies, is a metal plate with holes, also known as punching plate, perforated metal, perforated screen, mostly made of stainless steel and other metal plates. It is processed by a stamping machine or a milling machine and has the characteristics of long service life and no deformation.

Hole type of punching plate:

 

Rectangular holes, square holes, diamond holes, round holes, oblong holes, hexagonal holes, cross holes, triangular holes, long waist holes, plum blossom holes, fish scale holes, pattern holes, figure eight holes, herringbone holes, five-pointed star holes, irregular holes, bulging holes, special-shaped holes, louver holes, etc.

 

Perforated plate material

 

The materials are mostly stainless steel plates, aluminum plates, iron plates, copper plates, etc. Most of the ones seen on the market are perforated stainless steel plates. Perforated stainless steel plates have good chemical stability, beautiful shape, elegant color, strong three-dimensional sense and good decorative effect.

 

 

Performance characteristics

01 Porosity

The advantages of perforated stainless steel plates are as follows. The most direct appearance feature of perforated metal plates is porosity. Porosity means that the two spaces separated by the surface are permeable to each other, breaking the inherent boundaries between inside and outside, and creating a more open public space in form.

 

 

It can provide the city and users with the intuitive feeling they need, and truly achieves the mutual penetration of internal and external spaces. The porosity of the perforated plate allows the indoor and outdoor spaces to penetrate each other.

 

Perforated stainless steel plates will produce rich light and shadow changes under the sunlight or light. This effect will give the building a unique and flexible visual effect, with different light and shadow effects produced by different hole types.

 

 

02 Various combinations

 

Perforated stainless steel plates can be made into different shapes and sizes according to the needs of architects. Different connection combinations are possible, and the combination methods are rich and varied, with different panel combination forms.

 

 

03 Reducing sound levels

 

Studies have shown that perforated metal helps reduce sound levels, and its acoustic properties can help people reduce the impact of noise on health. When the frequency of the incident sound wave is consistent with the resonant frequency of the system, the air in the perforated plate will vibrate and rub violently, enhancing the absorption effect, forming an absorption peak, and significantly attenuating the sound energy.

 

When it is far away from the resonant frequency, the absorption effect is small. If a porous material is placed behind the perforated plate to increase the sound resistance, the absorption band of the structure will be widened. Perforated plates are used in the indoor and outdoor decoration of spaces such as concert halls, theaters, and cinemas.

 

 

How is the perforated plate realized?

 

There are two common piercing methods in modern times:

 

01 CNC punching machine

 

CNC punching is a common perforation method. The punching method of the machine tool is used to punch holes on the surface of stainless steel. The punching process can quickly punch holes on a large surface area of metal screens and panels.

 

02 Laser perforation

 

Laser perforation is the latest development of perforation technology. It is also a relatively expensive and complex technology with high precision and randomness.

Nowadays, perforated stainless steel plates have been used by designers in various fields, from industrial filters and sound insulation boards. To architectural interior decoration and landscape wall sketches, you can see it.

 

Application of perforated plate

 

It can be found in the fields of architecture, landscape, and interior design. Perforated stainless steel plates can unify the facades of buildings and separate spaces. While achieving semi-privacy and security, the space still maintains comfortable breathability and forms wonderful light and shadow effects.

Perforated stainless steel plates can be used as partitions or decorations indoors to create a low-key and simple fashion style. Light passes through different hole shapes. With the changes in light and shadow, it creates an extraordinary artistic effect, which not only ensures the transparency of the building, but also looks beautiful.

 

Chengdu Jianshe Road Primary School Jiangong Campus

 

This school is famous for its beautiful and cool appearance. Except for the bright yellow-green strips on the facade of the teaching building, the other colors are plain gray, creating a coordinated layout with the memory of the eastern suburbs. The campus full of "industrial style" is particularly unique on this street.

 

 

Walking into the campus, you can see "industrial style" perforated stainless steel plates everywhere. The use of perforated stainless steel plates as the walls of the aerial playground has better sound insulation and aesthetics than plastic partitions, and better ventilation.

The biggest highlight is that the aerial playground is surrounded by perforated stainless steel plates. On the plate surface, there are many Chengdu elements such as giant pandas, bamboos, teahouses, etc. "painted" by dense small holes, showing extremely rich urban characteristics and regional styles.

The above is a brief introduction to perforated stainless steel plate buildings. In terms of design, due to the material problem itself, the architectural plasticity of perforated stainless steel plates is actually greater, and they can be designed into different geometric shapes. The metallic color of perforated stainless steel plates will have a very mysterious color in the building, and it has a more stylish feel.
