Perforated Sheet Metal

Perforated Metal Sheet Malaysia

The perforated metal sheet was first introduced 150 years ago for the purpose of filtering coal in the mining industry. To understand the manufacturing and application of the perforated sheet metal, we will need to know ‘What is perforation’?. Perforation is the process of stamping or punching manually or mechanically on a material sheet to create certain patterns or shapes of holes. Perforated metal is made under this process by using a rotary pinned perforation roller with pointed needles to create regular holes on the sheet. Another manufacturing process is called ‘die and punch’ perforating which has a sheet with needles that punches holes into the sheet by repeatedly pressing on the passing metal sheet. Perforated sheet metal is ranging from light to heavy gauge thickness and available in several material types such as galvanized metal sheet, stainless steel, aluminum, cold-rolled steel, copper, brass, titanium, and plastic. It can be designed in either small or large openings depends on the requirements.

Perforated sheet metal is widely used in different industries for multiple purposes. For example, we will use it in the construction industry for certain functional and decorative purposes, such as it can be designed as a sunshade, sun protection slates, cladding, or facades for the building to achieve a better sun-blocking and heat dissipation functions. The perforated sheet installed in front of the building can reduce a load of air conditions to a large extent and result in an estimated energy saving of up to 45 percent per year. In addition, by installing it as ventilation grilles and sun protection screens of the ventilation and air conditioning system in the building, it can lead to a better airflow and shading purpose. We also can use it as the acoustic panels to improve the sound insulation in the room. A study has shown that perforated sheet metal can effectively reduce the sound level and limit the health effects caused by noise. It helps to control the noises while still providing us a comfortable environment. We also use it as a speaker’s cover which provides a high open area that allow sounds pass through and at the same time protects the speaker from any damage.

Perforated sheet metal also widely used in the automotive industry as oil filters, tractor engine ventilation, air filters or running boards. Besides, it can be made as machine baskets, gas purifiers, battery separator plates, coal washing or mine cages to be used in the chemical and energy industry. As we can see many examples mentioned above, there are many application functions available for the perforated sheet metal in our daily life & working environment.

Perforated sheet is available in the following designs and patterns:

It is also available in a wide range of hole sizes, materials, sheet sizes, and gauges for different application purposes. Round Hole Perforated sheet is widely used as sunscreen, decorative banister, balcony panel, air conditioning grilles, or ceiling panel. To use as perforated fencing and banister can keep secure of people and protect the properties from damage. The way of arrangement of the hole pattern can be classified into three types which are straight type, 45° staggered, and 60° staggered type. The 60° staggered type is considered to have the highest cost-effectiveness, the most durable and versatile one.
