Calculation of perforation rate of perforated metal plates

The opening rate refers to the ratio between the punching area and the entire board, commonly expressed as a percentage. Now let's use the following specifications as an example:

Round hole, 2mm aperture, 60 º misalignment, 4mm center to center distance, external dimensions 1M X 2M

Based on the above information and the following formula, we can conclude that the opening rate of this specification of punching net is 23%.

That is to say, the total area of the punched holes is 0.465 square meters (1M X 2M X 23%)

Calculation formula for porosity:

60 º misalignment of circular holes
