Are you ready to select panel type and colour for your steel building and are having difficulty in differentiating between Galvanized and Galvalume? Youre not alone.
Many contractors are familiar with working with both but consumers sometimes can lack the years of experience to know which is which and when each is best to use. You can refer tohttps://www.bungersteel.comto hire the best steel manufacturer.
Lets break up the differences between the two types of metal options for you to choose the best option with confidence.
What Is Galvanized Steel?
First things first. Galvanized steel was developed in the 19th century for use in commercial applications as an alternative to bare steel. Since then, it has been a staple of construction, manufacturing, and fabrication for its durability and resistance to corrosion. Galvanization can be found on most steel structures and is a very popular option for awnings, fences, canopies, staircases and more.
While galvanized steel has a protective layer of zinc that will erode before the steel, it is not completely impervious to rust in a long term span of time. Generally, galvanized steel will last approximately 15-20 years with minimal maintenance. It arrives ready to use and can be easily applied.
What is Galvalume?
Galvalume is a newer type of production steel sheet developed by Bethlehem Steel in 1972. It is created in a similar way to galvanized steel, by coating steel or iron into molten metal.
However, instead of using pure molten zinc such as in Galvanized steel, Galvalume is created by immersion into a molten mixture of zinc, aluminium, and silicon.
