Perforated Corten sheets are strong, durable and are used in many architectural applications, however, weight is an important consideration as Corten is substantially heavier then Aluminium.Graepels supply and manufacture perforated corten sheets. Corten is also known as a ‘weathering steel.’When using COR-TEN steel for Architectural purposes, the ‘stabilising’ process is an important consideration. In order to minimise rust stain due to the ‘runoff’ of rust in the initial weathering stages the panels must be some way stabilised before being installed on site.
The weathering process can be quickened through various process including pickling. Graepels recommend ordering perforated corten in advance of installment as ‘stabilisation’ of the panels can take between 2-6 months when leaving it weather ‘naturally’.
