EN 10025-5

EN 10025-5 European standard structural steels with improved atmospheric corrosion resistance is a low-alloy, high-strength, weather-resistant structural steel, commonly referred to as "weathering steel" or "Corten steel". Its core features include high structural strength, good low-temperature toughness, excellent atmospheric corrosion resistance, good weldability, unique aesthetic appeal, and low maintenance costs. It can autonomously form a stable oxide layer in outdoor environments, thereby significantly enhancing its rust resistance and notably reducing painting and maintenance expenses. Consequently, it offers unique advantages in applications such as construction, bridges, railway vehicles, containers, sculptures, and other scenarios requiring long-term exposure to atmospheric conditions with high maintenance challenges.
