Atmospheric corrosion poses a significant challenge to steel structures in urban environments, severely impacting their safety and durability. This paper examines effective processes for mitigating atmospheric corrosion risk and suitable strategies for sustainable development. One of the most important and effective methods for combating corrosion, particularly atmospheric corrosion in polluted cities like Tehran, is the use of protective coatings. These coatings, such as epoxy and polyurethane, act as barriers against moisture and harmful agents, preventing damage to structures. Additionally, cathodic protection techniques are explored as an effective means of preventing electrochemical corrosion. By utilizing sacrificial anodes, these techniques significantly reduce the detrimental effects of corrosion. The selection of appropriate materials, considering economic costs and availability, also plays a crucial role in minimizing corrosion risk. For instance, the use of stainless steel and corrosion-resistant alloys can enhance structural performance under harsh conditions. Furthermore, design requirements and the reduction of vulnerabilities in structures must be considered to extend their lifespan. The results indicate that incorporating these strategies into urban planning and design can enhance the durability of metal infrastructure, contributing to a safer and more sustainable urban life. These measures not only help preserve investments but also improve the quality of life for citizens.
