Is Weathering Steel The Same As Corten Steel?

                                                                     一：Is weathering steel the same as corten steel?

Weathering steel, best-known under the trademark COR-TEN® steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years.

                                                                            二：How long will weathering steel last?

120 years

Under ideal circumstances, weathering steel can last for decades. In fact, properly designed weathering steel bridges have achieved lifespans up to 120 years with minimal maintenance.Although weathering steel is slightly more expensive than ordinary structural steel, savings from elimination of the paint system offsets the additional material cost. Hence, the initial cost of a weathering steel bridge is very similar to that of a conventional painted steel alternative.

                                                                                       三：Is weathering steel strong?

Weathering steel is corrosion-resistant and extremely strong. Compared to other steels, weathering steel has a higher resistance against atmospheric corrosion as its protective coating inhibits further corrosion. Weathering steel has a longer life-span than bare cold rolled steel.
