Since the appearance of the punching process, the metal sheet no
longer sticks to the airtight and heavy traditional form, but opens
a new page for architecture with a light, ethereal and translucent
image. The characteristics of light transmission, sun shading and
ventilation make this translucent perforated aluminum plate popular
among architects, and it quickly demonstrates its unique charm on
the stage of various new building skins. The perforated aluminum
plate commonly used as building skin is made of aluminum and
aluminum alloy and other plates with good weather resistance as raw
materials. The regular or irregular hole effect on the surface of
the plate is formed by mechanical punching, forming a special
hollow texture and texture. The early perforated aluminum plates
were mostly made of holes with relatively simple and regular shapes
(square, rectangle, circle, cross, etc.) arranged neatly or
dislocated according to certain rules. Holes of different shapes,
sizes, densities, and arrangements bring rich and varied surface
forms to metal sheets, thus laying the foundation for personalized
architectural skin creation. Along with people's pursuit of
artistic beauty, perforated aluminum panels have also begun to jump
out of regular and conventional hole forms, and irregularly
arranged hole textures and patterned plates with various hollow
patterns have appeared, which have more and more artistic material
forms.
The perforated aluminum plate is a material made by stamping and
punching the metal aluminum plate with advanced numerical control
equipment and punching equipment. The metal plate treated by this
process can show translucency with a specific texture. According to
the different input parameters of the CNC equipment, the punching
equipment can be punched into holes of various shapes, such as long
holes, round holes, square holes, pentagonal holes, scale holes,
rhombus holes, plum blossom holes, herringbone holes, Character
holes and other special-shaped holes, etc., can also be obtained by
setting the perforation rate of the material to obtain perforated
aluminum plates with different densities and patterns. The
perforated aluminum plate can be divided into the following forms
according to the decoration form: punched flat plate decoration,
hollow plate decoration, punching profiled plate, punching pattern
decoration, concave-convex hole plate decoration, grille
decoration, local dot decorative body.
