ASTM A606 Corten Steel Sheets & Plates


The ASTM A606 When exposed to the weather, which is a weather-resistant steel, develops a protective rust layer known as patina. The steel beneath is protected from additional corrosion by this natural defense, which lowers the need for maintenance. Because of its great strength and availability in a variety of sizes and shapes, corten steel is a popular material for roofing, bridges, buildings, and other construction projects.

Type of ASTM A606 Corten Steel

ASTM A606 is a standard that covers several types of high-strength, low-alloy (HSLA) steels with improved atmospheric corrosion resistance. While commonly referred to as Corten steel, ASTM A606 itself isn't a specific type of Corten steel. There are actually multiple grades within the standard, such as Type 2 and Type 4, each with slightly different properties to suit various applications.

Power of ASTM A606 Corten Steel Sheets

Corten steel isn't just steel; it's a revolution in weather resistance. At Conquest Steel & Alloys, we're proud to be leading manufacturers of ASTM A606 Corten steel plates – the perfect choice for projects that demand both strength and enduring beauty.

The Corten Difference:

Here's what sets our ASTM A606 Corten steel plates apart:

  • Natural Protection: Forget constant repainting! Exposure to the elements forms a protective patina on the surface, a natural shield against further corrosion. This unique characteristic not only extends the lifespan of your project but also creates a distinctive aesthetic that weathers beautifully.
  • Unmatched Strength: Don't compromise on durability. Our Corten steel boasts exceptional tensile and yield strength, making it ideal for even the most demanding structural applications.
  • Low-Maintenance Marvel: Corten steel's self-protecting nature translates to minimal maintenance needs. Say goodbye to constant upkeep and hello to long-lasting performance.

ASTM A606 is a specification for high-strength, weather-resistant steel sheets. It provides guidelines for producing durable steel, ideal for structural and aesthetic applications in environments where resistance to weathering is crucial.

A606 can be used to produce COR-TEN steel, a branded type of weather-resistant steel. However, not all A606 steel is COR-TEN, as COR-TEN is a specific trademarked product with unique properties.

There is no single ASTM number for Corten steel. ASTM A606 is a common standard for producing Corten steel, but other ASTM standards may also apply, depending on the specific requirements and properties needed.

COR-TEN is a brand name, not a steel grade. It refers to a type of weather-resistant steel, which can be made from various grades of steel, chosen based on desired strength and other characteristics.
