Perforated Metal Mesh with Aluminium Sheet for Construction Fields
What Is Perforated Metal Mesh?
Perforated metal is a form of sheet metal which has been punched or
stamped with a machine to create a pattern of holes. It is also
known as perforated sheet, perforated plate, or perforated screen
and is commonly made from stainless steel, cold rolled steel,
aluminum and more.
Perforated metal was first developed around 150 years ago for the
mining industry as a means of filtering coal. Initially, the
perforation process was inefficient; involving laborers manually
punching individual holes into a metal sheet. Over time, the
process has improved through the use of machinery utilizing
punching needles arranged in specific patterns.
How Is Perforated Metal Mesh 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 North America, the thickness of the sheet
metal is specified in gauges; the larger the gauge number, the
thinner the metal. In the rest of the world, sheet metal thickness
is simply 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.
The most advanced method available is laser perforation. This
process is very sophisticated and precise, but also the most
expensive. Laser perforation produces results similar to rotary
pinned perforation with hot needles, but maintains a higher level
of consistency and control over the hole sizes and pattern.
Perforated metals mesh are very popular in contemporary
architecture as they lend themselves to creative and unique
designs. They also have a number of practical benefits:
Sun protection and climate control: Perforated metal mesh 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.
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.
Balustrade screening panels: Perforated metal sheets are used in
panels for balconies, stairways, and balustrades screens. They
offer weather resistant protection coupled with an attractive
Other industries that utilize perforated metals are:
Food and beverage: Used for drain dryers, wine vats, fish farms,
sorting machines, fruit & vegetable presses and baking trays.
Chemical and energy: Used for filters, gas purifiers, mine cages,
coal washing, battery separator plates and centrifuges.
Automotive: Used for oil filters, radiator grilles, running boards,
engine ventilation and motorcycle silencers.
Material development: Used for blast furnace screens, textile
printers and felt mills, cement slurry screens and glass
