Corten weathering steel is a type of steel that develops a protective layer of rust when exposed to atmospheric conditions.The two main types of Corten steel are: Corten A, which is typically used for architectural purposes and Corten B, which has been impact tested meaning it is often used in structures.
It has properties that are very advantageous for certain projects and we will discuss these below.
1 – Corten weathering steel is anti-corrosive
Corten weathering steel has anti-corrosive properties that gives it an advantage over other structural steels. The naturally occurring rust that it develops helps to lengthen the lifecycle of a weathering steel structure, which in turn keeps costs to a minimum.
2 – Buildings made with Corten require less paint
The protective layer of rust that Corten weathering steel develops when exposed to moisture and oxygen reduces the need for paint. This helps to avoid some of the issues and potential for damage created by volatile organic compounds found in certain paints.
3 – Corten is useful for heavy-duty structures
The strength and durability associated with Corten B makes it ideal for use in heavy and load bearing structures.
4 – Corten Weathering Steel has an attractive appearance
The protective rust that Corten weathering steel develops has a distinctive reddish-brown appearance that is particularly popular among architects and design engineers. It is often used in artistic, outdoor structures and contemporary applications.
5 – Corten Steel requires minimal upkeep
Corten does not only have architectural qualities. Due to its chemical makeup Corten is able to withstand elevated heat without it increasing corrosion meaning that it is ideal to use within chimney linings, log burners and fire pits.
