What to Know About Weathering Steel
First and foremost, "weathering steel" is often used interchangeably with "COR-TEN® steel," which is the U.S. Steel's trade name for atmospheric, corrosion resistant steel. As COR-TEN® steel became increasingly popular, other producing mills began to develop their own weathering steels. This is when ASTM International stepped in to establish what are now considered equivalent specifications to Cor-Ten® in most applications:
ASTM A588
A242
A606-4
A847
A709-50W


The fundamental benefit of weathering steel is its ability to resist corrosion by naturally developing an aesthetically-pleasing and protective patina. The atmospheric corrosion resistance of weathering steel enables it to be used unpainted in many structural and architectural applications for structures, including bridges, open-frame buildings, transmission towers, sculptures and more.
