COR-TEN® Steel is a high strength steel with a high weathering resistance. COR-TEN® has been a trademarked name used to generalize Weathered Steel. This steel alloy has been used in architecture and sculptural works, it eliminates the need to paint and provides a beautifully unique and aesthetically pleasing look while also providing great rust protection. COR-TEN® has a weather resistance greater than 4~8 times that of ordinary steel. Each of our COR-TEN® Steel Products at The Outdoor Plus are aged to look around 1 month of patina. The texture of the COR-TEN® Steel may be irregular, this is what gives our products and even more unique finish.
