What is corten steel plate ? why is it called corten?

Corten is a group of steel alloys which are primarily used for outdoor structures. They develop a protective coating called patina on the surface which prevents them from getting corroded. They do not need additional surface treatments and is cost-effective.

Corten steel plates can be found in railroad coal wagons and other harsh condition applications.The name of Corten plate material is derived from its two main properties- corrosion resistance and tensile strength.

Is corten sheet expensive? why ? what exactly its price in India ?

The corten sheets are generally more expensive than ordinary carbon steel sheets. The main reasons behind the high corten steel sheet prices are:

  • The alloying elements in the chemical composition and the manufacturing procedure.
  • The mechanical properties offered by cor ten steel sheet.
  • The distinct rusty appearance increases its demand as it is aesthetically pleasing for many architectural applications.

The price can vary with corten steel plate suppliers,
due to internal costing, market conditions, quantity ordered, customization needed and delivery location.
