Description

A 6.3mm staggered-pitch aluminium perforated sheet with 49% open area — the most open configuration in the 6.3mm hole group, with nearly half the surface open to perforation. At this level, the holes are the dominant visual feature of the sheet, with the aluminium bridges forming a secondary lattice rather than the primary solid face. The visual effect is quite different from the 40% version at the same hole size, despite sharing the same 6.3mm aperture.

This specification suits applications where maximising airflow or acoustic transmission through the panel is the primary objective: industrial and commercial ventilation grilles, acoustic absorption panels where a high open area is specified to target mid-to-high frequency absorption, machine guards, and exterior screening where wind-loading through the panel is a design consideration.
