You likely already know a lot about galvanizing, whether it is normal galvanizing or the hot-dip galvanizing. However, if you do not, galvanizing is a special process taken with steel or iron where it coats these metals with molten zinc. Have you ever noticed that steel or iron often has a special silver look? This has been done through the process of galvanization. This special process has been around for over 150 years and it has been able to protect steel and iron from corrosion. Now, you may simply be looking for some additional information regarding the galvanization process or you may be a professional working in one of the many galvanizing plants who is looking for some tips to improve the quality of the galvanization in your plant. Whatever your case may be, here are some ways to ensure quality galvanization.
Inspect the Coating
Dipping metals into incredibly hot molten zinc will eventually come out with a few flaws, especially when talking about galvanization. While it is impossible to avoid having a few flaws in your galvanization process, it is important for the galvanizing plants to inspect all materials before shipping them out to suppliers. Be sure that your plant is checking for spots on the coating, roughness or unevenness on the allow, or even lumpiness and runs that may have occurred from the metals being dipped improperly into the zinc pool. Giving all of your product a quality inspection will not only lead to happier customers but also a more satisfying experience with your employees.
Protrusions and Inclusions
It is all too often that galvanizing plants may have an issue where the allows end up settling down in the bottom or the top of a kettle of zinc. If you were to encounter the type of allow that settles at the bottom of the kettle, also known as dross protrusions, you may end up causing a negative effect on the surface of the submerged metal and cause mechanical malfunctions if not addressed properly. If you were to encounter the allow that floats on the top of the zinc, also known as flux and ash inclusions, then you may end up reducing the effectiveness of the coating on the metal.
Just like any other business that supplies a specific type of product to clients, it is important for places that specialize in galvanization offer quality inspections to ensure that their product is being shipped with the least amount of flaws as possible.
