Product Description

Corrosion resistant plate 

COR-TEN® is a weathering steel and was developed to avoid having to paint steel for protection. This means that it has increased resistance to atmospheric corrosion when compared to unalloyed steels. It achieves this by forming a protective rust-coloured oxide layer on its surface. Its alloying with copper and chromium ensure the formation of a firmly adhering protective layer of ‘rust’ which delivers a particular aesthetic appearance and weathering performance. COR-TEN® is not rustproof in itself. COR-TEN® is a registered trademark of the United States Steel.


It is vital to take expert suggest when using COR-TEN® as an architectural element.
It is main to understand the climate where it will be used, and it presents several construction challenges – design, detailing, fabrication and erection.

  • Welds have to be designed and executed to weather at the same rate as material being joined.

  • Areas where water can stay may experience higher corrosion rates.

  • In salt-laden air environments the protective patina may not stabilize but continue to corrode.

  • Moisture should not be trapped within and adequate ventilation to ensure wet-dry cycles.

Its normal surface weathering can lead to rust stains on nearby surfaces. Basic guidelines for the use of this steel are described in EN 10025-5, and the mechanical properties of weathering steels depend on which alloy and how thick the material is.
