**Abstract**

Currently, modern infrastructures utilize different materials such as metals, alloys, glass, plastic, wood, ceramic, silicate brick, and natural stones. The material's diverse composition, structure, chemical, physical, and mechanical properties with ease in utilization make metal utilization a priority for architects and civil contractors. The principal property that determines the quality and durability of infrastructure is the corrosion resistance and weathering resistance. The corrosion of metals can cause damage to concrete, building stones, wood, and other materials, leading to corrosive destruction. The corrosion protection of the structural steel used in reinforcements, load supports, and frames has become extremely important to meet the demand of modern infrastructure having 100 to 120 years of service life.
