Products Description
An ASTM A588 steel plate is a high-strength, low-alloy (HSLA) structural steel plate known for its superior atmospheric corrosion resistance. Often referred to as "weathering steel" or Corten steel, it forms a stable, rust-like patina when exposed to the elements, which eliminates the need for painting and reduces maintenance costs.

Features and properties
- High strength: A588 has a minimum yield strength of 50 ksi (345 MPa) and a minimum tensile strength of 70 ksi (485 MPa) for plates up to 4 inches thick. This makes it suitable for heavy-duty structural applications.
- Corrosion resistance: The key feature of A588 is its unique weathering ability. An alloying of elements like copper, chromium, nickel, and silicon encourages the formation of a dense, self-healing oxide layer (patina) when exposed to weather. This layer acts as a protective barrier against further corrosion, a process that is far more effective than with carbon steels.
- Aesthetic appeal: As the protective patina develops, the steel's surface turns a distinct rustic orange-brown color. This evolving appearance is highly valued by architects and designers for aesthetic purposes in buildings, facades, and public art.
- Durability and cost-effectiveness: By eliminating the need for regular painting and coating, A588steel provides a longer life cycle with significantly lower maintenance costs compared to other steels.
- Grades: ASTM A588 is available in several grades, including A, B, and K, which have slight differences in chemical composition and mechanical properties.
- Processing: It can be hot-rolled and is weldable, rivetable, or can be used in bolted construction. Heat treatment options such as normalizing or quenching and tempering are also available to meet specific project needs.
Common applications
A588 weathering steel is used in unpainted conditions for a wide range of outdoor and structural projects, including:
- Bridges: Especially in coastal or industrial areas, A588 is a popular choice for bridge components and girders due to its durability and corrosion resistance.
- Architecture and facades: It is widely used for building facades, curtain walls, and roofing systems where its unique aesthetic is desired.
- Outdoor structures: This includes stadiums, pavilions, railcars, containers, and fencing.
- Sculptures and art installations: The weathered, rustic appearance of the material is frequently used by artists for outdoor public art.
- Construction equipment: The high strength and corrosion resistance make it suitable for components of heavy machinery, such as loader arms and chassis.
FAQ
What is A588 plate?
Corrosion-resistant, high-strength, low-alloy steel plate. Available in three grades: A, B and K. Often referred to as Weathering steel. Has properties similar to COR-TEN® steel. Ideal for welding, riveting or bolting in construction applications, primarily for bridges and buildings.
Is A588 the same as Corten?
A588 is a type of weathering steel that's renowned for its exceptional corrosion resistance. With its unique ability to form a protective rust-like surface, it eliminates the need for additional coatings, reducing maintenance costs. ASTM A588 is also referred to as Corten® and covers structural shapes, plate, and bar.
What is the grade of Corten steel plate?
What Are types of Corten Steel Plate Grade ? There are mainly two Grades, namely Corten A and B. The Corten steel has a more orangish appearance compared to the mild steel mainly due to its copper content.
What is A588 material equivalent to?
The ASTM A588 grade A plate is equivalent to Corten A steel plate. ASTM A242 plate is equivalent to Corten B. Compared with common low alloy high strength steel such as A572 Grade 50, ASTM A588 and ASTM A242 has advantages of weathering resistant performances.
What is the difference between A36 and A588 steel?
ASTM A588 is a high strength low-alloy structural steel, while A36 is just carbon steel. Due to the difference in chemical content, A588 angle steel has more applications than mild A36 angle bar.
