As a high-performance steel, weathering steel has broad application prospects. However, its shortcomings cannot be ignored. By optimizing production processes, developing new welding materials, improving processing equipment and technology, and strengthening environmental supervision, the shortcomings of weathering steel can be effectively solved and its application in more fields can be promoted. In future development, the steel industry should further increase the research and development of weathering steel and contribute to the transformation and upgrading of my country's steel industry.
