The flooring is designed using a hexagonal pattern. The hexagonal pattern is perforated into the Corten metal sheets (Corten is also known as weathering steel). The design uses a mix of countersunk and flush holes which offer good grip. The panels were then shot peened to provide additional grip for added underfoot safety.

Graepels Cheslea Gold Flooring and Picture Perf


Kinsale, Co Cork

Graepels recently manufactured Chelsea Gold Flooring for this striking architectural project in Kinsale, Co Cork. The project’s brief involved designing a perforated floor which was functional and would blend seamlessly with the scenic surroundings of the harbour.

Manufactured in Corten Steel, the earthy tones of the perforated flooring perfectly contrast with the leafy greenery along the deck. In addition, the perforated flooring offers increased grip, which was essential for this waterside deck area.
