Corten A Corrosion Resistant Steel Plate

 

Corten A is a weather resistant steel created by alloying copper, chromium and nickel. In addition to this, Corten A has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facias. 

 

The material is not recommended for heavy load bearing applications – in this case, Corten B or S355J2W should be considered. The top layer of the material reacts with atmospheric elements to form a rust colored protective layer which not only makes the steel virtually maintenance free but also provides a pleasing and consistent finish.
