GB/T Q415NH Corten Steel
Designed for demanding structural applications, GB/T Q415NH Corten Steel forms a protective rust barrier when exposed to weather, dramatically reducing maintenance needs compared to ordinary steel.
What sets Q415NH apart? It's stronger than Q355NH but keeps the same weather-resistant properties, making it ideal for projects where load capacity and longevity are equally important. The steel develops a rich, stable patina over time, combining engineering performance with architectural appeal.
