Perforated sheet metal, also known as perforated plate or screen, have been used for over a century or more to make a pattern of holes, shapes, or slots. Perforating is the process of pressing or stamping manually on the sheet to form the given pattern of holes and slots. These metals were used across industries including construction, architecture, chemicals, food, and automotive in various areas, which are later elaborated upon in the post. The metals used for this process include stainless steel, brass, aluminum, copper, galvanized steel, and others. These ready-to-use sheets are available in various geometric shapes, sizes, and materials in the market. This post highlights on all important areas of perforated sheet metal.

  • Architecture: Perforated metal sheets are widely used as fencing screens, column covers, in gardens as sunshades, for cladding, and more.
  • Construction: They are used as ventilation grills, acoustic panels to reduce the noise levels as signboards, pipe guards, and more.
  • Automotive: Perforated sheets are used for engine ventilation in tractors, air filters, radiator grills, in bike silencers, oil filters, and more.
  • Chemical: Perforated sheets are used as filters, mine cages, battery separator plates, water screens, and gas purifiers among others.
