For perforated metal, typical thickness ranges are:
Ceilings/acoustic boards: 0.5 – 1.0mm
Internal partitions/feature walls: 1.0 – 3.0mm
Facades/sunscreens: 1.5 – 3.0 mm (depending on wind load and support)
Staircases/walkways: 5.0mm and above
For large panels or outdoor use, thicker materials offer better rigidity.
