Round perforation
Ø8mm
22.3% open area
The most open patterns. Used where absorption is the priority and the perforation is meant to be seen.
The standard hole. Thirteen patterns from 1.8mm up to 10mm, in straight and staggered grids.
Specifying this pattern
Name it as Ø8mm at 22.3% open. The size alone is not enough to identify a pattern: this range holds two patterns at 1.8mm, two at 2.3mm, two at 2.5mm, two at 3mm and two at 5mm, and within each pair only the open area differs.
Perforation is available plain or perforated on our panel systems. Whether this pattern can be run on a particular panel depends on the panel size and its edge detail, so confirm it with us before it goes in a specification.
Data are approximated into in/ft/gauge. See the SI unit catalog for exact measurement.
