ASTM A588/A588M

Under the ASTM A588/A588M standard, there are four grades of high-strength low-alloy weathering steel: Grade A, Grade B, Grade C, and GradeK. Their most essential feature is excellent atmospheric corrosion resistance, which is why they are commonly referred to as "weathering steel" or "Corten steel." These steels can be exposed to outdoor environments for long-term use without the need for painting, thereby reducing long-term maintenance costs. ASTM A588/A588M series steel plates also offer advantages such as high strength, lightweight, good toughness, excellent weldability and workability, environmental friendliness, and aesthetic appeal. They are highly suitable for components intended for long-term exposure to natural environments.
