It was none other than Ludwig Mies van der Rohe, the creator of the Barcelona Pavillion, (which is often described as one of the most beautiful 20th century buildings), who coined the phrase ‘less is more’. Van der Rohe could have been talking about perforated sheet!
What other material simultaneously provides so many design opportunities to combine its inherent strength to weight ratio and corrosion resistant qualities with a widely appreciated aesthetic appeal? By virtue of these outstanding attributes, perforated aluminium sheet is often incorporated into many architectural components as the primary element. These products would include balustrade infils, bar/counter fascias, ceiling panels, column casings, radiator/vent covers, wall cladding and so on.
It is often desirable to custom make perforated aluminium panels rather than fabricate from stock size sheets. This way the specifier retains much greater design flexibility by being able to incorporate plain borders and other unpunched areas, as well as, cut outs for lighting, vent ducts, etc. With the majority of round hole patterns being arranged on a 60 degree triangular pitch the plain borders are normally lost once pre-punched sheets are cut to size. Unless covered with a safety edge or hidden by some other component the resulting raw edge is a health and safety no no.
