Galvanized steel is generally created by coating steel with zinc. This process is called galvanization which ensures that the steel won't get corroded with rust. Galvanization was developed in 1837 and was subsequently named after its Italian inventor, Luigi Galvani. The hot dipping process was later introduced. Hot dip galvanization involves the process of coating the iron material, aluminum or steel with a layer of zinc by dipping it in hot melted zinc at a scorching temperature of about 860°F or 460°C. The zinc coated steel is then exposed to the atmosphere, allowing the zinc to react with the oxygen in the air to form zinc oxide. The zinc oxide then reacts with carbon dioxide to produce zinc carbonate which forms a faded gray layer all over the steel. This layer protects the steel from direct exposure to corrosive elements and conditions. This is why the zinc layer as it becomes a part of the steel is often called the 'sacrificial anode' layer. Galvanized steel often comes in the form of tubes, rolls and sheets and is available in varying thickness and strengths. It is mainly used in manufacturing products that are often exposed to moisture and extreme weather conditions. Some applications include automobiles, fencing, wrought iron gates, household appliances and building materials. The material is also utilized in high-tension electrical towers, protective gears, highway signs, and more. The construction industry is among the top consumers of galvanized steel. This product is often used for piping, support beams, handrails, barriers, heating as well as air conditioning ducts. Metal roofing is becoming increasingly popular because of its extreme durability, resistance to rust and ability to survive extreme weather conditions. Metal roofs are lightweight, recyclable, fire resistant an almost maintenance free. This material is highly resistant to corrosion. In fact, based on the reports of the American Galvanizers Association, any steel that is subjected to the galvanization process is 100 times more rust resistant than uncoated steel. The zinc layer of galvanized steel can also effectively resist cracking and loss of adhesion at the time it is formed into a new product. The zinc coating does not need any kind of special handling or protection during transport. Its unique metallurgical structure provides superior durability and resilience to mechanical damage during transport, building and service. Galvanized steel is also longer lasting than its alternative materials. It has a life expectancy of 50 years or more in most rural environments and around 25 years or more in severe urban and coastal settings. The stability of zinc in warm dry atmospheres is remarkable. The zinc oxide produced in the initial exposure remains firm and intact, preventing further reaction between the zinc layer and the elements. However, the life of galvanized steel may be reduced in most rural areas due to the adverse effects of aerial spraying of insecticides or fertilizers. These chemicals when in dry form may be harmless to zinc coatings. But when they are wetted with irrigation spray water or rainwater, destructive solutions may be formed which can affect the stability of the galvanized coating until it gets washed off with further wetting.
