Decorate your space with perforated corten steel sheets

The Perforated Corten sheet supplied by Graepels are strong, durable, and can be used in many architectural applications. However, weight is an important consideration, since Corten is considerably heavier than aluminium. A ‘weathering steel’ is also known as Corten.

There are also different finishes available for the plates, such as ASTM A588 Grade B Perforated Corten Sheet and polished sheets. Corten sheets and plates are graded A and B according to their composition and characteristics. In Corten Steel Sheets, an oxide layer forms on the surface, preventing further oxidation. Patina is another name for this oxide layer.

It is important to consider the ‘stabilising’ process when using COR-TEN steel for architectural purposes. Before the panels are installed on site, they must be stabilised in some way in order to minimise rust stains caused by the ‘runoff’ of rust in the early weathering stages.

Pickling can speed up the weathering process. Graepel recommends ordering Perforated corten Sheet in advance of installation as ‘stabilisation’ can take between 2-6 months.

Advantages Of Perforated Corten

  • Once corroded a concrete type texture forms on the surface giving added grip making it ideal for Perforated Corten steel sheet flooring providing drainage, texture and grip
  • Corten is a structural steel it has a higher tensile strength to other everyday steel perfect for perforated flooring, fencing and public sculptural pieces
  • Easy to form, perforate and weld
