Corten Steel Sheet

What is CORTEN steel plate?

Corten steel, also known as weathering steel or atmospheric corrosion resistant steel, often referred to by the trademark COR-TEN® steel (sometimes written as Corten steel). The name COR-TEN® refers to the two distinguishing properties of this type of steel: CORrosion resistance and TENsile strength.
Corten steel plate or sheet, is a type of alloy steel plate. When uncoated exposed to the weather, Corten steel plates would rust and the rust forms a protective coating on the external surface which slows the rate of future corrosion, thus to prevent the steel material from acidic environments. The oxidation process of corten steel sheets is accelerating through subsequent exposure to dry and wet periods and also through sandblasting. As a result, corten steel plate has increased resistance to atmospheric corrosion when compared to other steels.
so, it is commonly used in outdoor applications or environments where normal steel would be inclined to rust.

Advantages of ANHUILONG Corten Steel Sheet

  • Weather Resistance

AHL Corten steel has 4~8 times atmospheric corrosion resistance ability higher than ordinary steel.

  • Weldability

AHL Corten steel plate can be welded using either manual, gas-shield or submerged arc welding method.

  • Initial and Whole-life Cost Benefits

Cost savings from the elimination of any protective painting may much higher than the additional material costs. Meanwhile the minimal maintenance requirements of corten steel structures greatly reduce not only the direct costs of maintenance operations but also other indirect costs. The cost of weathering steel has been shown to be at least 5% lower than conventional painted steel alternatives in bridges using a HA Type 2 paint system.

  • Attractive Appearance

The appearance of corten steel would always change with time, and create unique surface according to the surrounding environment, which makes the corten steel building attractive and charming.

  • Speed up the Construction

The overall construction time would be reduced as both shop and painting operations are eliminated.

  • Environmental Benefits

Corten steel avoid the volatile organic compounds from painting and the disposal of blast-cleaning debris from maintenance work in the future.
