As the name implies, perforated metal panel is based on a variety of metal panel as the base material, through mechanical punching, CNC cutting and other modern processing technology, the panel according to a certain rule of various holes, forming a special texture texture or pattern. The perforated metal panel can also be treated in different ways according to the needs, such as electroplating, spraying, wire drawing, etc. Early perforated panel to mechanical stamping processing, can only produce a relatively regular hole, with the development of NUMERICAL control technology and plasma, laser, water knife cutting technology, now the perforated panel can be as digital engraving to present an arbitrary pattern. Aluminum alloy panel, copper (alloy) panel, stainless steel panel, weather-resistant steel panel and other panels with a certain thickness and stiffness are generally used as the original panel, and aluminum alloy panel is most used in building skin. When the perforation size and perforation rate is high, the stiffness of the panel is reduced, it is necessary to strengthen the ribs behind the panel, and the shadow of the rib is likely to be seen outside. Therefore, when designing, the panel partition of the perforated panel is controlled as far as possible, such as the width of the aluminum panel is about 1 meters, or the width of the panel thickness is relaxed appropriately. Perforated metal panel can more fully express the texture of architectural modeling, through the density of the holes, the size of the aperture, the concave and convex of the board surface to form different architectural skin effects. The use of perforated boards in the reconstruction of old buildings or new buildings with irregular facades can cover the buildings, simplify and unify the irregular facades originally including Windows, solid walls and structural beams and columns, so as to make the overall sense of the building stronger. For the perforated metal panel with large aperture and large perforation rate, the corrugating section can be rolled to improve its stiffness, and the appearance effect can also form a concave and convex shape. For some metal panels with high cost, such as copper panel, corrugated section can be used to reduce the thickness of the panel, so as to save cost.
