Corten Steel Sheet

Weathering steel is usually referred to by its trademark name COR-TEN (or simply Corten) and is known for its superior corrosion resistance and thickness. This is because the surface of the steel forms a protective oxide layer when exposed to the weather. In other words, the steel is allowed to rust in order to protect itself. This protective surface layer continues to regenerate over years of exposure.

Australian Steel is one of the leading Corten steel sheet suppliers in Melbourne, providing Corten steel sheet to suit a range of applications.

The Benefits

The protective properties of Corten steel sheet offer the following benefits:

  • It creates a unique industrial look that works as an interesting design feature
  • It makes for hard-wearing, cost-effective cladding
