Perforated Aluminum Sheet
Perforated Aluminum Sheet?
Perforated aluminum sheet is a type of sheet metal that has been stamped or punched with a machine to create a pattern of holes. It is can also known as perforated plate, perforated sheet, or perforated screen.
While there are many different choices for perforated metal, perforated aluminum sheet has many benefits. Perforated metal sheets made of aluminum allow for savings in weight and in passage of light, liquid, sound, and air. It can also provide a decorative effect. Another great reason to use perforated aluminum sheets are they are corrosive resistant and, therefore, can be used in indoor and outdoor design.
Aluminum Sheet is Made
The manufacturing process for perforated aluminum sheet begins with the design and need. First, deciding how thin and flat the aluminum should be, in order to be cut and bent into different shapes. The thickness of the aluminum is specified in gauges; the larger the gauge number, the thinner the metal.
The most common method to perforate aluminum involves the use of a rotary pinned perforation roller. This is a large cylinder with a series of sharp, pointed needles on the outside to punch holes into the metal. As the sheet metal is run across the perforation roller, it rotates, continuously punching holes in the passing sheet. The needles on the roller, which can produce a wide variety of hole sizes, are sometimes heated to simultaneously melt the metal to form a reinforced ring around the perforation.
