Products Description
Corten steel, also known as weathering steel, is a group of steel alloys, including copper, chromium, and phosphorus, that develops a stable, protective layer of rust when exposed to the elements, eliminating the need for painting and providing excellent corrosion resistance and high tensile strength. The "Cor-Ten" name itself stands for CORrosion resistance and TENsile strength, highlighting these key properties. It is used in various applications, such as sculptures, architectural cladding, bridges, and other outdoor structures.

FAQ
What is special about Corten steel?
Corten Steel is also known as a 'weathering steel', as the steel forms a protective layer on its surface under the influence of the weather; and it is this protective layer that gives Corten far superior resistance to atmospheric corrosion, compared to other steels.
Is Corten steel A588?
ASTM A588 is also referred to as Corten® and covers structural shapes, plate, and bar. This alloy is made up of copper, chromium, nickel, and other elements that give it its weathering resistance properties.
What is A588 steel equivalent to?
The ASTM A588 grade A plate is equivalent to Corten A steel plate. ASTM A242 plate is equivalent to Corten B. Compared with common low alloy high strength steel such as A572 Grade 50, ASTM A588 and ASTM A242 has advantages of weathering resistant performances.
Why is Corten steel so expensive?
One of the most practical considerations when choosing between Corten and mild steel is cost. Corten steel is more expensive than mild steel due to its unique composition and the additional processing required to create its weather-resistant properties.
How long will Corten steel last?
Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.
