About the material
Perforated galvanized steel is galvanized sheet punched with a repeating pattern of holes. Hole size, shape and spacing set the open area — the percentage of the sheet that is void — and that figure governs airflow, visibility and how much strength the sheet retains.
Punching exposes bare steel at every hole edge. Galvanized is the sensible substrate for that reason: zinc corrodes in place of the steel at a cut edge, so the pattern does not become the first point of failure.
A perforated sheet is less stiff than a solid one and behaves differently when formed or fastened, so panel spans and fixing centres need to account for the pattern.
The stocked pattern is a Ø3.18 mm round hole on a 60° staggered layout, 5.56 mm centre to centre across the sheet and 4.81 mm between rows, giving roughly 30% open area.
