Perforated metal panels are ideal for use as ventilation, acoustical panels, passive sun shading, sunscreens, covers, enclosures, dividers, and more. They can also be used to control the passage of air, light, and sound.
ATAS offers numerous hole size and placement combinations for perforated metal panels. While standard rounds holes are the most economical, custom shapes and variations are available at an additional cost and with design limitations.
An aluminum substrate is recommended for all exterior perforated applications due to its inherent corrosion-resistant properties.
Hole Size x Center to Center Distance x Orientation and the Open Area Produced
Example: ATAS Standard Pattern “A23” is: .25” x .5” OC Staggered, 23% OA
Translation: The holes are ¼” in diameter, spaced ½” apart center-center diagonally at a 60 degree angle, which produces 23% open area, or metal loss – 23% of the me
