How Perforated Steel is made

The manufacturing process of perforated steel begins with a sheet of steel metal. The most common method of steel perforation uses a rotary pinned perforation roller. A perforation roller is a large cylinder covered in sharp-pointed needles to punch holes into the metal.

The sheet metal is run across the perforation roller. It is rotated continuously while punching holes in the passing sheet. The roller contains needles that are capable of producing different hole sizes. These needles are sometimes heated so the metal can be melted simultaneously, forming a reinforced ring around the perforation.

Perforated Steel Patterns

Another common method of producing perforated steel is called die and punch perforating. A sheet containing needles is repeatedly pressed onto the passing metal during this process. The sheet with needles then punches holes into the sheet. The pieces that remain from the punching will then be sheared off, and the machine will smooth the surface. This method is very efficient and can quickly perforate a sheet with a large surface area.


Another method that is the most advanced is called laser perforation. This method is precise and sophisticated but also the most expensive. The results of laser perforation are similar to those of rotary pinned perforation with hot needles. The only difference is that laser perforation maintains a higher level of consistency as well as control over the pattern and size of the holes.

Types of Perforated Steel

The different types of perforated steel include:

Round Hole Perforated Steel

Round perforated steel is cost-effective, requires little maintenance, and is easy to use. Round-hole perforated steel is suited for HVAC system components. It is also ideal for interior design applications.

Round Hole Perforated Steel

Square Hole Perforated Steel

This type of perforated steel is aesthetically pleasing with a high strength-to-weight ratio. In addition, square-punched holes are larger than other types of holes. As a result, square perforated steel is perfect for a variety of enclosures.

Square Hole Perforated Steel

Rectangle Slot Perforated Steel

This perforated steel type is often used in screens and other filtering applications. It also provides strength and is affordable.

Hexagonal Hole Perforated Steel

This type of perforated steel is popular in industrial and architectural applications. It is a popular option for partitions, interior space dividers, or any other type of unique application.

Applications of Perforated Steel

The applications of perforated steel include:

Climate Control and Sun Protection

Perforated steel sheets are an excellent way of providing rooms with airflow and shade. They are often used as sun protection screens where ventilation is required. The porous nature of perforated steel allows the free movement of air. This results in substantial energy savings on ventilation, heating, and air conditioning.

Noise Reduction

Perforated steel sheets are often used for noise reduction in roof systems and walls. Perforated steel sheets can reduce the adverse effects of noise on workers’ health in noisy environments.

Balustrade Screening Panels

Perforated steel sheets are utilized in panels for stairways, balconies, and balustrade screens. They bring weather-resistant protection coupled with an attractive design.

Food and Beverage

Perforated steel is used for wine vats, drain dryers, sorting machines, fish farms, baking trays, and fruit and vegetable presses.

Chemical and Energy

Perforated steel is used for mine cages, battery separator plates, coal washing, centrifuges, gas purifiers, and filters.


Perforated steel is used for radiator grilles, engine ventilation, running boards, motorcycle silencers, and oil filters.

Material Development

Perforated steel is used for textile printers, felt mills, glass reinforcement, cement slurry screens, and furnace screens.
