A perforated sheet’s open area is expressed as a percentage, which indicates how much of the sheet is punched holes, and how much is metal. Perforated metal sheets have 30% open areas. This means that 30% of a sheet are holes and 70% are metal, such as aluminium or steel.

How to calculate tthe open area of perforated metal？
Calculating the open area of perforated metal is essential for determining its functionality in various applications. The open area refers to the percentage of the total surface area that consists of holes or openings. To calculate the open area, you’ll need to know the following parameters:
- Čuovgga diamehter (D): Metálla perforašuvdnačuozáhagaid diamehter, mii dábálaččat mihtiduvvo tuššain dahje millimehteriin.
- Guovddáš-guovddáža gaskka (S): Gaska guovtti lagaš čuolmma guovddážiid gaskkas, mii mihtiduvvo ovtta čuolmma gaskkas nuppi čuolmma guovddážii.
Here’s the formula to calculate the open area of perforated metal:
Rabas areála (%) = [(π * D^2) / (4 * S^2)] * 100
Gos:
- π (pi) lea sullii ovttalágan 3,14159:in.
- D is the hole diameter.
- S is the center-to-center hole spacing.
Dá leat lávkkit mo rehkenastit rabas areála:
- Mihtit čuohppan metálla čuolmma diameahtara (D). Dát mihtideapmi galgá váldojuvvot ovtta čuolmma gaskkas gitta nuppi čuolmma guovddážii.
- Mihtit gaskka-guovddáš čuolmma gaskka (S) guovtti lagaš čuolmma gaskkas. Mihtit fas ovtta čuolmma gaskkas gitta nuppi čuolmma gaskii.
- Plug these values into the formula mentioned above.
- Calculate the open area as a percentage.
Let’s illustrate this with an example:
Oaivvildat ahte dus lea čuohppan metálla mas lea 0,25 čuođi (6,35 mm) čuolmma diamehter (D) ja 0,5 čuođi (12,7 mm) čuollan gaskka (S).
Rabas areála (%) = [(π * 0,25^2) / (4 * 0,5^2)] * 100
Rabas areála (%) = [(3,14159 * 0,0625) / (4 * 0,25)] * 100
Rabas areála (%) = [(0,19635) / (1,0)] * 100
Rabas areála (%) ≈ 19,64%
Rabas areála (%) = [(3,14159 * 0,0625) / (4 * 0,25)] * 100
Rabas areála (%) = [(0,19635) / (1,0)] * 100
Rabas areála (%) ≈ 19,64%
Nu ahte dán ovdamearkkas lea čuohpaduvvon metálla rabas areála sullii 19,64%. Dát mearkkaša ahte sullii 19,64% olles areálas leat čuolmmat dahje rahpasat, ja fas proseanta lea čavga materiála.

At huijinmaterials mii fállat buot dárbbašlaš formlaid movt rehkenastit proseantta rabas areálas, vai beasat veahkehit du válljet rivttes rabas areála perforerejuvvon metállapanelaide du prošektii.
Open area of perforated metal for specific applications
The open area of perforated metal panels holds significant importance as it serves as a critical factor in assessing the suitability of a specific profile for your intended application. Whether you’re considering it for purposes like ventilation, acoustic control, or lighting, understanding the open area is pivotal.
However, it’s essential to recognize that the open area alone isn’t the sole determinant in achieving the desired outcome with a perforated metal product. Achieving the desired open area involves considering hole size and pitch—the distance between the centers of holes in adjacent rows—both of which hold equal significance.
It’s worth noting that each combination of hole size and pitch contributes to distinct performance characteristics, even when the open area remains consistent. Therefore, a thoughtful selection of hole size and pitch is crucial to tailor the perforated metal product to meet your specific requirements.
