ANSTEEL(SZ:000898) Xin Hua She·2025-11-14 03:07Core Insights - Weathering steel, a low-alloy steel made by adding certain alloying elements to carbon steel, is widely used in construction, bridges, and towers due to its corrosion resistance [2] Group 1: Industry Overview - Traditional rust prevention methods for steel primarily involve painting, which requires significant amounts of coating materials [4] - Weathering steel develops a protective oxide layer in natural environments that serves a similar purpose to paint, eliminating the need for organic coatings and reducing maintenance [6] Group 2: Technological Advancements - A new technology called "weathering steel rust layer stabilization treatment" has been developed by Angang's researchers, allowing for the rapid formation of the protective oxide layer on weathering steel [6] - This technology has been applied in major engineering projects, including the Yanqing-Chongli Expressway over the Daqin Railway and the largest weathering steel bridge in China, the Linyi Yellow River Bridge, contributing to local ecological protection [8]
