Calculate the open area of a perforate sheet based on the diameter of the spacing.
Note: the material thickness should not exceed the margin width and the diameter.
Choosing the right perforated metal sheet is crucial for airflow, stability and design. Whether for ventilation systems, façade cladding or industrial applications, the open area percentage has a significant impact on overall performance.
Our recommendation: First define the specific application. This will help you make informed decisions regarding materials, perforation patterns and sheet thicknesses.
