Galvanized steel is most commonly used as roofs for houses, sheds, etc.. However, one of the major limitations of such roofs is the noise that is created in the monsoon season, during which it rains continuously for several days to months. The noise disturbs the normal working of people and also their lifestyles. Thus there is a need to create roof coatings which reduce this noise.
Application of sound damping coatings will reduce noise and also help improve the durability and effectiveness of these steel roofs. Providing such roofs to people is not only a step towards innovation, but also helps in making lives of people living/working under these roofs better. The aim of this study is to improve the sound damping properties of the galvanized steel used for structural applications. Since a lot of houses in India are made up of steel in roofing applications, the outcome of this work will directly impact the common man living under such roofs.
