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.
