ANSTEEL(SZ:000898) Xin Hua She·2025-11-14 05:06Core Viewpoint - Weathering steel, a low-alloy steel with added alloy elements, is essential for construction and infrastructure due to its corrosion resistance properties [2][6]. Group 1: Weathering Steel Characteristics - Weathering steel forms a protective oxide layer in natural environments, providing rust resistance similar to traditional coatings without the need for paint [6]. - The formation of the oxide layer takes several years and can lead to issues such as rust liquid dispersion and streaking during the process [6]. Group 2: Technological Advancements - A new technology called "weathering steel rust layer stabilization treatment" has been developed to quickly form the protective oxide layer on weathering steel surfaces [6]. - This technology has been applied in significant engineering projects, including the Yanqing-Chongli Expressway and the largest weathering steel bridge in China, contributing to local ecological protection [8].
