Galvanisation is a chemical process of covering a steel with a layer of zinc. This layer protects the steel from getting corroded easily. This procedure is named after Italian Luigi Galvani, who invented the process.
Hot Dipped Galvanized Steel
Galvanised steel is prepared for the process called the Hot Dipped Galavanisation. The steel passed through a bath of molten zinc. Usually, the zinc is at a temperature of 460°C or 860°F. Then the steel which has already been coated with zinc is exposed to the atmosphere. The zinc will then react with oxygen in the atmosphere and forms zinc oxide. Then it further reacts with carbon dioxide in the atmosphere, forming zinc carbonate. This forms a dull gray layer on the surface of the steel, protecting the it from being rusty. At this stage, the zinc layer has become part of the steel.
Forms and Uses
Galvanised steel is used everywhere. It is available in many forms, such as galvanised wire, galvanised pipes, and galvanised cable drums for industrial use. Galvanised steel frames are used in building homes. Car components like the body of buses and trucks are also made of this type of steel. Several household appliances such as air conditioning housings, washing machines, and hair dyers also use this metal. It is utilised in protective gears, high tension electrical towers, highway signs, wrought iron gates, metal pails, and other items.
