high quality rusted prime weathering corten b steel factory supplier

Corten B steel is a corrosion resistant steel, also can be called weathering resistant steel or atmosphere corrosion resistant steel. Exposing the weather condition, the surface of Corten B steel can develops a layer patina, which can protects the steel from deeper corrosion. Corten B steel also is a high strength low alloy steel, so it can used in higher strength and longer period cycle material conditions.

COR-TEN B steel is becoming more popular by roll formed product end-users. Its unique look and naturally oxidizing finish make it especially desirable for many architectural projects. COR-TEN B has increased resistance to atmospheric corrosion when compared to other steels. COR-TEN B resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and save the cost for painting or rust-prevention maintenance.

3. How Corten B steel stop continue rusting and its application

Corten B Steel never completely stops rusting. The weathering process occurs after the panel come out. It eventually decreases and from that point on the finish acts as a protective coating on the base metal. 

This protective coating essentially stops the corrosion. Laboratory analysis of the rust shown that the alloying elements in the steel, such as copper, chromium, and nickel produced insoluble compounds that clogged the pores at the rust and steel interface, ending the regeneration. 

ASTM COR-TEN B is better suited for heavy and load bearing structures
