This process has numerous advantages to the people using it as it produces a form of metal that is way stronger than a metal which has been fortified by a cast or a machine part. With regards to metals like steel and iron that are the most often used materials in the construction industry‚ this durability and strength is the main factor to their appeal and their functionality. Forgings involve great capital expenditure for tooling‚ machinery‚ personnel and facilities

Chemistry Report – How does Galvanizing prevent Rusting? Galvanization is the process of applying a protective zinc layer of coating to steel or iron to prevent rusting. The most common form of galvanization is hot-dip galvanization. Hot-dip galvanization is the process of coating iron or steel‚ which are less reactive‚ by passing the metal via a molten bath of zinc at high temperatures. Hence‚ when the solution gets exposed to the atmosphere‚ pure zinc reacts with oxygen to form zinc oxide
