What Is Perforated Metal
Perforated metal, also known as perforated sheet, perforated plate, or perforated screen, is sheet metal that has been manually or mechanically stamped or punched to create a pattern of holes, slots, or decorative shapes. Materials used to manufacture perforated metal sheets include stainless steel, cold rolled steel, galvanized steel, brass, aluminum, tinplate, copper, Monel, Inconel, titanium, plastic, and more.
The process of perforated metal sheets has been practiced for over 150 years. In the late 19th century, metal screens were use as an efficient means of separating coal.
Modern day perforation methods involve the use of technology and machines. Common equipment used for the perforation of metal include rotary pinned perforation rollers, die and punch presses, and laser perforations.
How is perforated metal made?
The manufacturing process for perforating metal starts with sheet metal. Sheet metal is thin and flat, and can be cut and bent into different shapes. In many area of the world, sheet metal thickness is measured in millimeters.
The most common method of perforating metal uses a rotary pinned perforation roller. This is a large cylinder with 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 which forms a reinforced ring around the perforation.
Another common method is "die and punch" perforating. During this process, a sheet with needles is repeatedly pressed onto the passing metal which punches holes into the sheet. The pieces remaining from the punching are then sheared off and the surface is smoothed. The die and punch method is very efficient and can perforate a large surface of sheet very quickly.

1. Perforated metals are very popular in contemporary architecture as they lend themselves to creative and unique designs.
2. Sun protection and climate control: Perforated metal sheets are excellent at providing rooms with air flow and shade, often used as sun protection screens in rooms that require ventilation. Although they appear to be a design element, their permeable nature allows the free movement of air, resulting in substantial energy savings on heating, ventilation and air conditioning.
3. Noise reduction: Perforated metal sheets are often used for noise reduction walls and roof systems. In noisy environments, they can limit the adverse effects of noise on workers' health.
4. Balustrade screening panels: Perforated metal sheets are used in panels for balconies, staircase, and balustrades screens. They offer weather resistant protection coupled with an attractive design.
5. Food and beverage:Used for drain dryers, wine vats, fish farms, sorting machines, fruit & vegetable presses and baking trays.
6. Chemical and energy: Used for filters, gas purifiers, mine cages, coal washing, battery separator plates and centrifuges.
7. Automotive: Used for oil filters, radiator grilles, running boards, engine ventilation and motorcycle silencers.
