Aluminum punching metal alumite for architecture, buildings and furniture

■ Overview -The punching metal is a material made in a metal plate punching (punched) with a mold. ・ It is used for buildings and residential devices, taking advantage of various characteristics such as ventilation, ventilation, shading, light -shielding, sound insulation, sound absorption, and thermal radiation. ・ It has the beauty that can be accented as a design or blend into the city. ・ The diameter of the hole (hole diameter) is φ (pie or pie), and the length of the hole to the circularity of the next hole is represented by P (pitch). P continues in the longitudinal direction on a constant scale. * The angle of the part is made at 60 degrees. It is called 60 degrees Chidori. The main stock is 60 degrees staggered. Standed scale ... H1,000XW2,000, H1,250XW2,500 ・ The mold for producing punching metal differs depending on the plate thickness and the pole diameter pitch. ・ The end of the product changes with the mold used. -The molds used in stock are not symmetrical as shown in the figure. ・ The jumping type will be different in one row. ■ What is alumite? -Alumite refers to a method of coloring punching by electrolysis. ・ By performing anodized processing, the strength is increased and it is difficult to corrode. ・ Our alumite inventory is performed an alumite process after punching the fabric material 1100. Therefore, the cross section of the hole is also colored. ■ 3 types of fabric materials are in stock ・ 1100: Aluminum is 99%or more. It is an alumite guarantee material. ・ 1050: Aluminum with a purity of 99.5%or more. ・ 5052: Aluminum alloy. It is stronger than the above two types. ■ What is the hole rate? -The percentage of plates that are punched through the punching process are represented by the hole rate, which accounts for the overall area of ​​the hole (hole). -The punching metal changes the hole rate depending on the size of the hole and the interval between the pitches. ・ The narrower the pitch between the pitch, the more holes are punched and the hole rate increases. ・ It is also possible to calculate the weight of the board at the hole rate, how much hole is open to the board. ・ Please refer to it for choosing by application and image.
