You know how “Kleenex” is used when referring to a “tissue?” Or “Chapstick” is used when referring to “lip balm?” Similarly, the terms “COR-TEN®,” “cor-ten,” “corten” and “weathering steel” are used interchangeably when referring to atmospheric, corrosion-resistant steel, which can be a tad confusing…
Let’s be clear:
COR-TEN® is the U.S. Steel’s trade name for atmospheric, corrosion resistant steel while weathering steel and corrosion-resistant steel are the generic terms.
