Galvanized steel is perhaps one of the most important innovations in the modern world. It's safe to say that the modern world wouldn't even exist without galvanized steel, and we'd still be living in thatched-roofed buildings no more than 10 stories high, riding horse-drawn carriages down cobblestone roads. Galvanized steel is in almost every modern convenience today, from buildings and public works to almost every aspect of the automotive industry.
Over time, scientists invented the galvanizing process, which involves applying a protective layer of zinc to a piece of metal (usually steel or iron) to prevent rusting. This is usually applied to sheet metal. Steel sheets can be coated in a number of ways so they are protected from corrosive agents and their appearance can be improved. Galvanized steel sheets are formed into flat sheets and are galvanized in two ways. One is through an electro-galvanized coating, applied at ambient temperature. This ensures that the tensile properties of the base steel remain unchanged. The other is hot-dip galvanizing at high temperatures. This changes the properties of the base steel.
It is no exaggeration to say that galvanized steel is the best choice for a variety of manufacturing purposes, whether it is the construction of high-rise buildings or the mass production of automobiles. It is strong, sustainable, reliable, flexible and the most cost-effective metal available to all mass producers.
Galvanized steel is much stronger than ungalvanized steel, mainly because the former has a protective layer that also acts as a reinforcement, giving it better compressive and tensile strength. This is true of most galvanized steel, but electro-galvanized steel is especially strong. But perhaps the strongest type of galvanizing is a process called hot-dip galvanizing, in which the entire steel sheet is dipped in molten zinc, which tempers the steel and bonds the zinc at the molecular level, making it the strongest known one of the materials.
The galvanizing process not only makes the steel sheet stronger, but also makes it very durable. Essentially, zinc cladding protects steel from almost every possible external factor, be it extreme weather conditions, rapid and constant temperature changes, shock, compression or even tension. Galvanized rolled steel doesn't actually rust either: the zinc doesn't react with oxygen, protecting the stronger (albeit brittle) steel underneath. Regardless of the state of galvanised steel sheet, it will last longer. Life expectancy is greatly extended even in the harshest environmental conditions, in enduring areas or in places with a lot of sun, rain and snow. In fact, you don't need to keep changing materials.
