Perforated metal sheet
Perforated metal sheet is a product that is made from sheet steel that has been fed through a machine that punches out round holes (or other designs). These holes can be straight rows or staggered to increase the amount of the openings. Typically the perimeter of the sheet has a boundary where holes are not punched; this adds stability to the sheet. The removed metal from the holes can be recycled but it also increases the cost of the product. The larger the hole size (or increased amount of holes), the greater scrap volume, and therefore costs can be increased.
Perforated metal sheet comes in a virtually endless variety of sizes, gauges, hole shapes and material types. Hole diameters range from a few thousandths of an inch to more than 3 inches, punched in material as thin as foil or as thick as 1-inch steel plate. From lightweight decorative elements to load-bearing structural components, perforated metal offers unique opportunities to combine strength, functionality and beauty.
