Corten A B Grade Corten Steel Planter Box

COR-TEN has served as weathering steel (atmospheric corrosion- resistant steel). Corten steel plate has successfully overcome rust, steel's most weakest. When exposed to the atmosphere without painting, corten steel begins to rust in the same way as ordinary steel. BUT soon the alloying elements in COR-TEN cause a protective surface layer of the fine-textured rust to form, thereby suppressing corrosion rate. Since its development in 1993, the COR-TEN has been used in every field where steel applied, such as bridges, railway vehicle and buildings. At present, COR-TEN are attracting attention as being suited for resources and environmental concerns as well as reducing life-cycle costs.

Benefits of weathering steel

Reduced toxic emissions: No oil-based coating is used, which reduces emissions of volatile organic compounds.
No contaminated blast debris in habitats: Because the steel is not painted, no periodic maintenance blasting is required.
Cost savings of 10 percent or more initially and even more over the life of the structure: No painting and steel's durability mean reduced costs.
Long life and high performance: Weathering Steel has been used on bridges for many decades and performs well in most environments.
