Weathering steel manufacturers bring you to understand the weathering steel product process

weathering steel product process

Weathering steel, also known as COR-TEN® steel, is a type of steel alloy that forms a rust-like appearance on its surface when exposed to the elements. This process, called weathering, provides the steel with a protective layer that prevents further corrosion and deterioration. The following is the process of producing weathering steel products:

1. Raw Material Selection: The key ingredient of weathering steel is a type of steel known as low alloy or high strength steel. This type of steel contains added elements like copper, chromium, nickel, and phosphorus.

2. Manufacturing: Weathering steel products can be produced using various manufacturing techniques such as hot rolling, cold rolling, and forging. These processes involve shaping and forming the steel to the desired size and shape.

3. Surface Treatment: Once the steel has been formed, a rust-like oxidized layer (patina) will begin to form naturally over time. However, to accelerate the process, manufacturers can use various techniques such as acid washing or abrasive blasting to create a roughened surface that promotes the formation of the patina.

4. Quality Control: As with any product, quality control is essential to ensure the product meets the required standards. Weathering steel products undergo a series of tests to ensure they meet the required specifications for strength, durability, and corrosion resistance.

5. Application: Weathering steel products are commonly used in outdoor structures such as bridges, buildings, and sculpture. The unique rust-like appearance of the steel adds to the aesthetic appeal of the structure while providing a protective layer against corrosion.

In summary, the process of producing weathering steel products involves selecting the right type of steel, manufacturing the product, treating the surface to promote patina formation, conducting quality control checks and applying the product to outdoor structures.
