Imagine a manufacturing process that was nearly 100 percent green. Sound too good to be true? An often overlooked but sustainable way to produce aesthetically pleasing metal pieces for different applications is, in fact, a very green practice. Perforated metals are commonly used in a variety of architectural applications, but exceedingly are seeing growth in areas outside the industry. Examples include applications for sound suppression, microwave and EMI/RFI radiation containment, filtration and purification of air, water and gases, as well as decorative uses.
The holes in perforated metal provide solutions to a number of design problems. Typically, round holes, square holes, rectangles, triangles, slots and decorative patterns are commonly punched. Hole sizes range from a few thousandths of an inch in diameter to more than three inches, while the materials that can be perforated can be as thin as foil or as thick as a one-inch steel plate.
There’s actually no secret at all to the sustainability of this manufacturing process. As holes are punched in the material, the scrap is collected by the specialized perforator performing the work. That material can then be recycled and formed back into new sheets of metal to be perforated later. Additionally, the finished piece of metal can be completely recycled after its architectural life cycle ends.
