GNEE is one of the leading suppliers and exporters of ASTM A588 Corten steel. ASTM A588 Grade A and A588 Grade B offer improved corrosion resistance over standard carbon steel by forming a protective oxide film on the metal surface that retards further corrosion. Both are high-strength, low-alloy weathering steels with a minimum yield strength of 50,000, allowing for cost savings by constructing lighter sections in buildings.
SA588 Gr A Corten steel manufacturers supply SA588 Gr A corten steel plate is an HSLA structural steel with a minimum yield strength of up to 50 ksi, offering resistance to atmospheric corrosion for bridges and buildings where strength and durability are required.
