Corten B is a weather resistant steel and the chemical composition of Corten b OR Cor-Ten B has been designed to provide a high resistance to atmospheric corrosion, especial in urban environment. Corten b or Cor-Ten b is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels.

corten b steel plate specification:
Standard: ASTM
Thickness: 2-460mm , Width: 1500-3200mm, Length:6000-12000mm

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.

Weathering steel plate Cor-ten B is best known under the trademark COR-TEN steel and sometimes Cor-ten B is written as Corten B without the hyphen.Weathering means that due to their chemical compositions COR-TEN A and COR-TEN B steels, when utilised unprotected, exhibits increased resistance to atmospheric corrosion compared to unalloyed steels. This is because it forms a protective layer on its surface under the influence of the weather.When using the weathering corrosion resistance steel plate Cor-ten B in construction presents several challenges.
