ASTM A242 Corten B Weather Resistant Steel Plate 345-355 MPa Yield Strength for Outdoor Structures
ASTM Corten B steel plate is a hot-rolled structural steel product with enhanced atmospheric corrosion resistance, designed for outdoor applications and decorative uses. This weather-resistant steel forms a protective oxide layer when exposed to the elements, providing long-term durability without requiring painting or maintenance.
- Superior atmospheric corrosion resistance
- Self-protecting oxide layer formation
- Minimal maintenance requirements
- Yield strength of 345-355 MPa depending on thickness
- Ideal for heavy load-bearing structures
- Cost-effective alternative to painted structural steels
