Description

A 40mm staggered-pitch aluminium perforated sheet at 40% open area — the most open staggered-pitch configuration at the 40mm hole diameter. At 40% open area, 40% of the aluminium surface has been removed by perforation. The visual effect is dramatic: very large circular holes in a closely-spaced offset pattern, producing a surface that is unmistakably open and substantially transparent at close range, with relatively narrow bridges for the scale of aperture.

At 40mm and 40% open area, this specification offers the highest open area of any staggered-pitch product at the 40mm hole diameter, and the largest individual aperture in the Gooding Aluminium round-hole range. Architectural facade screens, open parking structure cladding, large-scale external screening, and industrial ventilation facades are the key applications. Adequate framing and fixing support should be specified given the large hole size and high open area.
