Perforated sheet metal: the material of choice for modern construction and decoration Perforated metal plate, as a kind of metal material products after special processing, has been widely used in the field of modern architecture and decoration because of its unique hole design and various material choices. This paper will introduce the perforated metal plate in detail from the aspects of material, mesh specification, size, characteristics and application. First, material selection Perforated metal plate is mainly based on various metal plates, such as stainless steel plate, aluminum plate, iron plate, copper plate, etc. Among them, aluminum alloy plate has become the most used material in building skin because of its light material, good chemical stability, beautiful shape and other characteristics. Stainless steel plates, because of their high strength and corrosion resistance, perform well in situations where large loads or harsh environments are required. Second, mesh specifications and dimensions Perforated metal plate mesh specifications are diverse, the aperture size can range from 0.2mm to 100mm, the common aperture is 2mm, 4mm, 6mm, 8mm, 10mm and so on. These specifications of perforated panels are suitable for both interior decoration and outdoor construction. At the same time, the size of the perforated metal plate can also be customized according to actual needs, common plate sizes are 1000*2000mm, 1200*1200mm, 1500*1500mm, etc., special sizes can also be customized. Iii. Characteristics Excellent process: perforated metal plates are made of advanced CNC machinery for precise drilling or laser cutting technology, with high surface finish and a variety of pass shapes. High strength and durability: Due to the use of high-quality metal materials, it has good strength and corrosion resistance performance. Optimized air flow: The porous structure facilitates air flow and is suitable for components such as filters or air deflectors in various ventilation systems. Good sound absorption and sound insulation: the porous structure helps to absorb sound wave energy, thereby reducing the efficiency of noise transmission. High degree of customization: Different specifications and patterns can be customized according to different needs to meet individual requirements. Iv. Application Perforated metal plates are widely used in the field of construction. It can be used as a building skin, through the density of holes, the size of the aperture, the concave and convex of the board to form different building skin effects, enhance the overall sense and beauty of the building. At the same time, it can also be used as a sunshade, curtain wall insulation filler. In addition, in garden landscape design, perforated metal plates are also often used as decorative parts such as walls and gallery frames, creating a stylish and modern aesthetic feeling. In summary, perforated metal plate with its unique material, diverse mesh specifications and sizes, excellent characteristics and a wide range of applications, has become the preferred material in the field of modern architecture and decoration.
