Frequently Asked Questions

Learn more about A606 steel sheet.
ASTM A606 and ASTM A588 are both weathering steel specifications designed for improved atmospheric corrosion resistance. The main difference is product form: A606 is a corrosion-resistant steel sheet, while A588 is a heavier structural steel plate used for applications such as bridges, buildings and outdoor structures.
ASTM A606 is available in Type II, Type IV and Type V. Type IV is the most common and may contain additional alloying elements beyond carbon, manganese, sulfur and copper to further improve corrosion resistance, depending on the manufacturer.
ASTM A606 is a weathering steel sheet specification, while COR-TEN® is a trademarked steel product with similar atmospheric corrosion-resistant properties. A606 is often compared to COR-TEN because both are designed to develop a protective rust-like patina when properly exposed to the atmosphere, helping improve durability in outdoor applications.
