EN 10025-5

EN10025-5 is the European standard for high-strength low-alloy weathering structural steel. The core characteristics of steel under this standard include high structural strength, good low-temperature toughness, excellent atmospheric corrosion resistance, good weldability, unique aesthetic value, and low maintenance costs. It is commonly referred to as "weathering steel" or "Corten steel." Weathering steel can form a stable oxide layer on its own in outdoor environments, significantly enhancing its rust resistance and greatly reducing painting and maintenance costs. Therefore, it offers irreplaceable advantages in applications such as construction, bridges, railway vehicles, containers, sculptures, and other scenarios requiring long-term exposure to the atmosphere and where maintenance is challenging.
