ASTM A588 Grade B Corten Steel Plate 0.3-40mm Thickness Weather Resistant Structural Steel
ASTM A588 Grade B Weather Resistant Steel Plate, also known as Corten A Steel, is a high-strength, low-alloy structural steel that develops a protective rust-like appearance when exposed to weather. This self-protecting characteristic eliminates the need for painting and provides long-term durability in outdoor applications.
Forms a protective patina layer within 6 months of exposure, creating a natural barrier against corrosion from rain, snow, fog, ice, and other weather conditions.
