Used in interior and exterior design manufacturing applications, perforated metals are metals that have been punched, or perforated, with various shaped holes in a series or a pattern.

Examples of these hole patterns include: centers and squares, staggered rounds, round and line squares, straight square slots, round slot end, side staggered, diamond, cross, chain link and hexagon as well as decorative cutouts like flowers and celestial bodies.

Industries that make use of perforated metals include filtration, insulation, construction, food service and waste management. Perforated metal products in these industries include panels, filters, strainers, tubes, piping inserts, trash cans, vents, speaker covers and countless others. The number one industry for perforated metals is architectural design. Architectural perforated metals are used decoratively, as patio furniture, light fixtures and the like, and as access restriction utilities, like screens.

Perforated metals may be made from a number of metals; the decision of which is mainly determined by application requirements, like heat resistance, erosion resistance, hardness, etcetera. Metals and alloys that are commonly perforated include copper, zinc, steel, stainless steel, galvanized steel, cold-rolled carbon steel, aluminum, brass, titanium and others. Read More…

Sheet metals perforation is performed using two likely methods, depending on the repetitiveness, complexity and general design of the hole patterns. Simple perforations may be fabricated using a standard punching press, which is a large press containing whatever hole pattern the manufacturer requires. To achieve the desired perforation, sheet metal is simply fed through the press, which punches it.

For more complex perforation designs, like decorative panels that use many non-repetitive shapes, manufacturers use a sectional XY axis punching press. This press is usually CNC controlled, thus ensuring precision and accuracy.

To perforate using the XY press, sheet metal is secured to the machine and slowly moved around underneath one to several stationary single-shaped punching rams, which create a detailed pattern on the metal as it moves in the direction of the hole design. This process is long, but patience rewards the metal worker with complex, precise, decorative perforated sheets and panels. Though both manual and CNC punching methods have their merits, CNC punching tends to be preferred due to lower labor costs, higher production speeds and greater process repeatability. Each perforation creates a piece of scrap metal, which can be recycled into more sheet metal. This practice increases the savings associated with the already cost-effective metal perforation process. Perforated metals also tend to be very lightweight and therefore easy to transport and handle. Any way that you look at it, perforated metals are a great investment.
