ASTM A588 covers high strength, low-alloy structural steel shapes, plates, and bars with improved atmospheric corrosion resistance that is intended for riveted, bolted, or welded construction. When properly exposed to the atmosphere, this steel is suitable for many applications in the bare/unpainted condition.
