What is Galvalume?
Galvalume is a metal coating comprising three important metals: steel, zinc, and aluminum. Contractors prefer to use Galvalume on certain metals because it eliminates the risk of corrosion. Also, it is lightweight, energy-efficient, and affordable. Metals can easily corrode and wear away in certain environments over time, but Galvalume eliminates the risk of this happening. Galvalume brings out the best characteristics of metal, providing a longer lifespan and durability. Essentially, Galvalume is a metal coating comprising three important metals: steel, zinc, and aluminum. Contractors prefer to use Galvalume on certain metals because it eliminates corrosion risk and is lightweight, energy-efficient, and affordable. For example, a popular application of Galvalume is in metal paneling and steel building roofing, as this provides outstanding corrosion resistance that may be common in outdoor settings. Apart from this, Galvalume also has high resistance to rain and even extreme conditions such as hurricanes, snow, and hail. Galvalume is also quite popular in different commercial and industrial settings, including hospitals, schools, and other steel buildings, as well as agricultural structures and facilities. They are also widely used in industrial applications, such as in factories, warehouses, and so on. All in all, everything that involves steel structure can benefit from Galvalume and its characteristics.
What is Galvanized Steel?
Galvanization is the process of coating steel with a protective zinc oxide coating to prevent oxidation or rusting. Galvanized steel is ordinary steel sheets that are hot-dipped in zinc to eliminate the risk of possible corrosion. Galvanizing steel is crucial because iron can easily rust when exposed to any kind of water or moisture. Therefore, Galvanized steel is one of the most popular types of steel. The reason for this is due to its high durability, strength, and anti-corrosion characteristics. The Galvanization process creates reliable and durable steel products by providing them with superior protection. Galvanizing also helps protect the inner layer of steel. This way, the lifespan of your steel and metal products extends and can stay intact for up to a couple of decades. Apart from Galvanized steel’s construction and industrial applications, manufacturers commonly use the process to make corrosion-resistant objects, including nails, nuts, and bolts. Moreover, Galvanized steel is also quite widely used in piping, which reduces the risk of corrosion and rust in water pipes. You can also easily spot Galvanized steel in public places, such as on benches, staircases, walkways, ladders, and more.
What Are the Differences Between Galvalume and Galvanized Steel?
Although both serve as a coating to a steel core, you might not spot any difference by definition.
They both may sound similar, due to which you might be skeptical between these two. However, these metal finishes are ultimately two different coatings done on a steel panel to enhance their strength and durability.
Components
The components of Galvalume and Galvanized Steel are the factor that makes these metal coatings different from one another. The main components of Galvalume include three important metals- steel, zinc, and silicon, all of which are in exact ratios. Thus, it is basically a carbon-metal base that is hot-dipped into aluminum and zinc alloys. The end result of the repeated coating will guarantee the following ratios: 55% aluminum, 43.4% zinc, and 1.6% silicone. The greater heat and corrosion-resistant properties of this metal coating are mainly due to these components.
Galvanized Steel, on the other hand, is coated by zinc oxide via hot-dipping. Therefore, the only component present in Galvanized Steel coating is zinc. Fabricators do this by submerging the carbon steel into molten zinc, having a temperature of about 680° Fahrenheit.
