Perforated sheet metal is produced by means of stamping or punching sheet metal. The metal produced is quite versatile – it can serve as a lightweight decorative material or a solid structural piece that bears a heavy load. It is also quite long lasting, often not needing any replacement for many years. Maintenance requirements are minimal, making this type of metal quite cost-effective.

There are plenty of reasons why an architect may choose to use a perforated material to allow air and sound to pass through. This type of industrial metal is also used in the food and beverage industry, in which case its purpose is to allow liquids and sometimes solids to pass through its holes. Other industries in which it plays a major role include agriculture (for bee hives, grain dryers, fish culture, hammer mill screens, sorting machines, silo ventilation and more), brewing (for hop screens and malting floors), construction (for acoustic panels, perforated pipe guards, ventilation grills and other applications), chemicals (for centrifuges, filters, pulverizers and drying machine baskets), electricity (for radiator covers, cable trays, water screens and battery separator plates), quarries and brick making (for oven trays, drying trays, elevator buckets and rotary and vibrating screens), cryogenics (for beat transfer screens), railways (for embossed floors, plates and running boards as well as radiator covers, filters, ventilation grills, luggage racks and acoustic panels), textiles (for dyeing and drying machines, textile printers and felt mills) and the sugar and distilling industry (for centrifuges, filters, pulp presses, diffuser linings and sugar beet washers). No matter what context it is being used in, the benefits of perforated sheet are numerous and a few are listed below.

Wide Range of Available Thicknesses

The metal is easy to produce in a wide range of thicknesses. This makes it useful for all sorts of industries. If it is to be used in the food and beverage industry, it can be produced as a thin but sturdy sheet that will allow food and beverage products to move through the pores. It can also serve as a weight-bearing component of a building that allows a room to breathe.

Excellent Durability

Perforated metal is quite strong and durable, making it an excellent way to give an attractive appearance to a structural component that needs to bear heavy weight.

Application to Acoustics

The metal can be manufactured in such a way that it absorbs specific frequencies of sound. This makes it very useful in controlling the acoustics of a building. It can also be used in systems for canceling out certain sound frequencies such as jet engine nacelles and structures that enclose noisy compressor or air conditioning units. By limiting noise, workers in various industries can be protected from the damaging effects of high sound levels.In the characteristics and functions listed above, perforated sheet is superior to other types of industrial metal such as expanded metal and wire cloth, and it is the only type of metal that can perform certain functions. When considering which type of metal you are going to use for a project, it’s important to consider more than cost alone. Matching the ideal type of metal to each specific function will enhance the quality of your work and save you money in the long run.
