Corten steel is becoming more popular by roll formed product end-users.Its unique look and naturally oxidizing finish make it especially desirable for many architectural projects.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.The most commonly used is corten A steel plate and corten B steel plate. corten Weathering steel has increased resistance to atmospheric corrosion when compared to other steels.COR-TEN resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and negates the need for painting and costly rust-prevention maintenance over the years.

— Hot forming:
This operation may be normally carried out in a temperature range of 800 °C to 1050 °C. If it is required to use a different temperature, it is advisable to carry out a normalizing treatment at the end.
— Flame cutting:
This operation can be normally carried out with the usual methods. In general no preheat is required, but operation on plates with a temperature of less than 10 °C should be avoided.
— Welding:
COR-TEN A/B plates can be easily welded using all common procedures used for mild steel plates (spot, GTAW, GMAW, SMAW). Considering the chemical analysis, it can be stated that COR-TEN A/B steel is not subject to cold cracking. Welded structures fabricated with COR-TEN A steel does not normally need thermal stress relief treatment. Please contact A/B braservice for the choice of welding products.
— Drawing:
In spite of its excellent mechanical characteristics, COR-TEN A/B can be moderately drawn.
— Cold bending:
COR-TEN A/B is suitable for very strict bending operations.
