SA588 Grade A is a type of High-Strength Low-Alloy (HSLA) weathering steel (often called Corten), known for enhanced atmospheric corrosion resistance, forming a stable, rust-like protective layer, used in bridges, buildings, and rail cars, offering good strength (min 50 ksi yield) and weldability, making it ideal for exposed outdoor structures.
