Description

A 6.3mm square-pitch aluminium perforated sheet at 15% open area — the most opaque specification in the 6.3mm hole group, and the only square-pitch product at this hole diameter in the round-hole range. The square pitch organises holes into precise horizontal and vertical rows, creating a formal grid across the face that contrasts with the offset texture of the three staggered-pitch options in the same hole size. At just 15% open area, the aluminium surface is predominantly solid, with the holes providing measured ventilation or acoustic porosity rather than a notably open visual character.

This combination suits applications where a formal geometric pattern is preferred over the organic look of staggered perforation, and where low porosity is a structural or functional requirement: acoustic barrier and semi-opaque screen panels, secure ventilation covers for sensitive equipment, and architectural cladding panels where the grid alignment is specified to match adjacent building grid elements.
