Weather / Atmospheric Corrosion Resistant Steel
(Corten A/B)

Corten steel is up to eight times resistant to atmospheric corrosion compared to unalloyed steels and is characterized by its special alloy elements including copper, nickel, chrome and phosphor.
Enhanced corrosion resistance is based on the oxide layer called “patina” which forms naturally on the steel surface.
Corten is widely preferred in architectural applications for its elegantly brown-orange surface.

Typical Applications:

Corten A: Chimneys, tanks, boilers, oven parts, ship hulls, locomotives, wagons, trailers, trains and metros, containers, building facias, landscaping and architectural applications (sculptures, dust-bins,planters, streetlights, fences)
Corten B: This grade is more suitable for heavy load bearing applications or applications where high
