**7. Summary**

New materials like physical vapor deposition sheets, doped glass, lightweight steel structures, and wood plastic composites bring new challenges to the fasteners and complete infrastructure. The material selection by the architecture and civil engineers by comparing corrosion potential, esthetic appearances, and commercial viability should be encouraged. The structural steel and its maintenance equipment should be designed and fabricated to minimize the electrode potential of the modern infrastructure. Suspension cable fittings of the cable bridges or overhanging eaves/roofs should be electrochemically similar to the cable material. The anchoring of the same should be appropriately grounded to avoid the charge flow in suspension cables. The green building concept further increases the challenge by unifying nature and construction materials. Plant roots, water, soil, and algae may lead to corrosion problems in the structure. Further studies are required to understand corrosion potential and its prevention for the high life of modern infrastructures.
