Description

A 15mm square-pitch aluminium perforated sheet at 20% open area — the only square-pitch product in the 15mm hole size group, and the most opaque specification at this aperture scale. The square layout and restricted open area give this product a notably solid, architectural character: the 15mm holes are large enough to read as bold circular features at a glance, but the wide spacing between them means the majority of the aluminium face is unperforated.

This combination is the right choice when a large, clearly defined hole is required within a predominantly solid surface: perforated panels that must function as a partial security barrier, entrance screening where some visibility through the panel is needed without a high open area, and exterior architectural cladding where wind loading through the panel must be limited. The regular grid pattern is visually distinct from the offset pattern of the 15mm staggered 40% variant.
