A242 Weldable Weather Resistant Steel Plate Corten Steel Outdoor Products
Product Description
ASTM Corten B steel grade is a hot rolled product of structural
steel in technical delivery conditions with improved atmospheric
corrosion resistance. The steel grade Corten B is according to ASTM
standard which with the yield strength of 355MPa and 345MPa which
is based on the different thicknesses.
Corten B – weather-resistant steel which is better suited for heavy
and load-bearing structures.
The material forms its own protective layer when exposed to
atmospheric elements. Essentially, the top layer corrodes which
then protects the steel beneath it. The natural finish does not
normally require any form of maintenance such as painting, which
makes the material a highly cost-effective alternative to other
structural steels.
Painting and maintenance will be required if the structure is
continually wet as a protective layer will not form. A good example
is where the base of the structure meets with the ground or is
partially submerged.
