Form assembling to tungsten inert gas welding, sheet metal fabrication techniques can be hard to keep track of. To understand how these methods work, we will break down the fundamentals of a newer skill, perforating. What is involved in perforated plates?

This is a procedure of manually or mechanically punching to create a pattern of holes or decorative shapes on a metal sheet. Most sheet metal fabricators utilize stainless steel, cold-rolled steel, galvanized sheet metal, brass, aluminium, tinplate, copper, titanium, and plastic for this fabrication technique.

Several industries use perforated plates in their varied applications such as architecture, automotive, chemical and energy, construction, food and beverage and material development. In architecture, this applies in infill panels, sunshade, cladding, column covers, metal signage, site amenities and fencing screens. Air filters, oil filters, silencer tubes, radiator grilles, ventilation grids; in automotive industry.

While perforated plates may strictly seem like an aesthetic element, there are significant benefits to this method, including the following:

  • A study in 2007 by William Steward depicted that perforated plates help reduce sound levels, its acoustic performance limits health effects from noise, which is ideal for employees who work in buildings near highways and facilities with heavy machinery.
  • Building structures that require ventilation use sun protection screens made of perforated metal, leading to excellent airflow and shade.
  • Perforated plates’ permeable nature allows the free movement of air, resulting in substantial energy savings on heating, ventilation and air conditioning.
    Also, depending on the building’s location, solar irradiation can be decreased by approximately 77.9% percent.
