ASTM Weather Resistant Steel
ASTM Weather Resistant Steel, often known as Corten steel, is a type of steel designed to withstand tough weather conditions while maintaining its strength and appearance. Unlike regular steel, which can rust and degrade quickly when exposed to the elements, ASTM Weather Resistant Steel develops a protective layer of rust called patina. This patina forms naturally when the steel is exposed to air and moisture, creating a barrier that shields the underlying steel from further corrosion.
The unique property of this steel is its ability to protect itself from rust without needing additional coatings or frequent maintenance. This makes it a popular choice for outdoor structures like bridges, building facades, and sculptures. Even if the surface gets scratched, the patina layer regenerates and continues to offer protection.
ASTM Weather Resistant Steel is made from a blend of materials, including carbon, silicon, manganese, phosphorus, sulfur, chromium, copper, and nickel. These elements are combined in different proportions to create various grades of steel with specific strength and durability characteristics.Â
Overall, this type of steel provides a long-lasting and low-maintenance solution for many outdoor and structural applications.
ASTM Weather Resistant Steel Supplier
Corten Steel Tube is a top manufacturer and supplier of ASTM Weather Resistant Steel. This specialized steel is designed to withstand harsh weather conditions and resist corrosion over time. Its unique feature is the formation of a protective oxide layer, known as patina, which forms when the steel is exposed to the elements. This layer acts as a natural shield, preventing further corrosion and extending the lifespan of the steel.
Our Weather Resistant Steel Plates come in various types and grades, including Corten A and ASTM A242. These steels are commonly used in outdoor structures like bridges, containers, tanks, and building facades. Their self-healing property means that if the steel gets scratched, the oxide layer regenerates, maintaining its protective qualities without the need for additional coatings or frequent maintenance.
The composition of Corten steel includes carbon, silicon, manganese, phosphorus, sulfur, chromium, copper, and nickel. Different grades offer varying strength levels, such as a minimum yield strength of 355 MPa and a tensile strength ranging from 470 to 630 MPa. For example, the A558 Corten A Plates, which are 3mm thick, have a minimum yield strength of 275 MPa and a tensile strength of 410 MPa.
Whether you need steel for construction, outdoor applications, or other long-lasting projects, our Weather Resistant Steel Plates provide durability and reduced maintenance needs.
