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.
ASTM A588 Grade A (A588GRA) is a low-alloy high-strength weathering steel plate according to the American standard, known for its strong resistance to atmospheric corrosion. It can be used outdoors for extended periods without the need for painting.
ASTM A588 Grade B (A588GRB) is a high-performance structural material that perfectly combines high strength, excellent atmospheric corrosion resistance, and unique aesthetic value. When applied in suitable environments and appropriately designed, it provides a robust and aesthetically plea...
ASTM A588 Grade C (A588GRC) is an exceptional structural material that combines high strength, excellent atmospheric corrosion resistance, and unique aesthetic appeal. It embodies the design philosophy of "form follows function" by utilizing the natural corrosion process to create structur...
ASTM A588 Grade K (A588GRK) is a high-strength, low-alloy structural steel plate with excellent atmospheric corrosion resistance and unique aesthetic value. It offers a long service life in outdoor environments, low maintenance costs, and strong visual impact, making it particularly suitab...
