Q295NH Corten Steel Plate

Q295NH is a low-alloy structural weathering steel developed under GB/T 4171, similar in function to ASTM A242 Type 1 or Corten A. It is specially formulated to provide excellent atmospheric corrosion resistance, especially in environments with moisture, rain, or periodic wet-dry cycles.

Compared with Q295GNH, Q295NH typically has a slightly lower alloy content and is more often used in lightweight outdoor structures, steel curtain walls, and landscape steel projects.
