This process derives its name from the use of zinc galvanizing, which has been used since 1742.
The primary purpose of galvanizing is to protect metal surfaces from corrosion. Corrosion typically occurs when the surface of certain metals, including steel and iron, is exposed to the elements over a long period of time. By adding a coat of zinc through galvanization, these metals are adequately shielded against such degradation. The result is a piece of material that’s not only more durable but also more resistant to wear-and-tear.
So, how does this process work? The most common method today is known as hot-dip galvanizing. This involves submerging the steel or iron product into a bath of molten zinc. The temperature of this bath usually sits at around 860 degrees Fahrenheit (460 degrees Celsius). As the steel or iron product is submerged, it reacts with the molten zinc, causing it to form layers of zinc-iron alloy on its surface.
Once this reaction has taken place and the alloy layers have formed, the galvanized metal is then cooled and inspected for quality assurance purposes. After passing inspection, what’s left is a piece of steel or iron that’s not only stronger than before but also significantly more resistant to corrosive elements.
Apart from hot-dip galvanizing, there are other forms of this process like electro-galvanizing and sherardizing. But regardless of method, one thing remains consistent: The goal is to protect the underlying metal from corrosion, hence extending its service life. In essence, ‘What in galvanized steel’ speaks to the endurance and longevity that the galvanization process imparts unto steel and iron products.
In conclusion, the galvanization process acts as a lifeguard for your steel, fortifying it against the relentless onslaught of rust and corrosion. Whether you’re a homeowner looking for a reliable material for your project or an industry professional seeking long-lasting materials for manufacturing, galvanized steel is an option worth considering due to its protective properties resulting from the galvanization process.
