Hexagonal Holes Perforated Aluminium Sheet

Honeycomb Geometry for Maximum Open Area

The defining advantage of hexagonal perforation is the open area it achieves relative to the material removed. Where round holes leave curved, unused gaps between adjacent apertures, hexagonal holes with their straight six-sided edges pack tightly together in a honeycomb like arrangement, reducing the solid bridges between holes to the minimum needed for structural continuity. The result is a sheet that transmits significantly more air or light, per square metre than a round-hole or square-hole sheet of equivalent thickness and hole pitch.

Across the Gooding Aluminium hexagonal range, open area percentages run from 41% at the tightest configuration up to 59% at the most open. For comparison, round-hole perforated sheets in the same catalogue typically peak at around 50% open area, and square-hole patterns sit lower still. This makes hexagonal perforation the strongest option in the range where the primary requirement is to maximise throughput — whether that is airflow across a ventilation panel, light transmission through a screening surface, or acoustic transparency in a speaker enclosure or ceiling tile.

Five Hole Sizes from Fine to Large-Scale

The hexagonal range spans five distinct hole sizes, each producing a different visual scale and open area percentage. At the smaller end, the 6.0 x 6.9mm hole creates a fine-grained honeycomb texture with 52% open area — close enough in scale to read as a uniform surface from a short distance, while still allowing substantial airflow at close range. This suits applications where the sheet will be viewed up close and a refined finish matters: speaker grille panels, equipment enclosures, or small-format vent covers.

Moving through the mid-range, the 9.0 x 10.4mm size offers the tightest open area in the range at 41%, making it the most visually opaque hexagonal option. The 12 x 14mm and 15 x 17mm sizes both deliver 56% open area but at different physical scales — the smaller of the two producing a more detailed pattern and the larger reading as a bolder, more prominent honeycomb.

At the largest end, the 20 x 23mm hole achieves 59% open area — the highest in the entire hexagonal range. At this scale, the individual hexagons are clearly visible and the sheet reads as an open lattice rather than a solid surface. This is the strongest choice for large-format ventilation panels, external screening, or any application where maximum airflow and a bold graphic presence are both required.

Structural Integrity Despite High Open Area

One of the practical benefits of hexagonal perforation is that the honeycomb bridge network distributes stress more evenly than circular or slotted hole patterns. In a round-hole layout, the solid material forms irregular, curved-edged ligaments between holes. In a hexagonal layout, the bridges between apertures are straighter and more uniform in width, creating a mesh-like structure that resists bending and flexing more predictably across the sheet.

This matters in practice because high open area percentages inevitably reduce the cross-section of solid material carrying loads. A sheet at 59% open area has removed more than half of its parent material, so the geometry of what remains becomes critical. The consistent bridge widths in a hexagonal pattern help the sheet maintain flatness and rigidity over larger unsupported spans, reducing the likelihood of oil-canning, waviness, or localised distortion that can affect sheets with less uniform perforation layouts.

All stock size sheets in this range are manufactured either on 1.2 or 2.0mm thick aluminium in a standard 2000mm x 1000mm or 2500mm x 1250mm format. Where a project requires  bespoke sheet sizes, or a specific alloy grade, Gooding Aluminium can do this — contact sales@goodingalum.com.

Fast Dispatch for Hexagonal Perforated Sheets

Standard orders are dispatched within 2–5 working days and delivered via an overnight nationwide service. For projects requiring sheets cut to non-standard dimensions, supplied with plain border margins, or finished with a polyester powder coat or anodised surface, Gooding Aluminium’s processing and finishing services can accommodate these requirements within a short lead time.

Free material samples are available for all sheets in the hexagonal range. Samples are posted first class and typically arrive within a couple of days, giving specifiers and purchasing teams the opportunity to assess the hole size, open area, and surface finish before placing a full order. The honeycomb pattern is one where the physical sample makes a real difference — the interplay between hole scale, light, and viewing distance is difficult to judge from a screen image alone.
