Description

The only square-pitch product in the 3mm hole size group, and the most opaque specification across the entire round-hole category at just 12% open area. The square pitch aligns holes in straight rows horizontally and vertically, producing a regular grid pattern that is visually distinct from the offset texture of the three staggered-pitch versions at the same 3mm hole diameter. With only 12% of the sheet area open, this aluminium perforated sheet delivers strong structural integrity and significant acoustic barrier performance.

The very low open area means this sheet can function effectively as a partial acoustic barrier, allowing minimal sound transmission while still presenting as a perforated aluminium surface rather than a solid panel. It is also used where precise grid alignment is required in the visible face — architectural screening, protective covers, and decorative panels where the regularity of a square layout is a design requirement. The straight-row alignment also simplifies folding or cutting along a consistent line.
