PRODUCT DETAILS
Product Details
There are many different types of galvanizing processes depending on the desired results or performance of the finished product. The most popular methods include hot-dip galvanizing, electroplating, mechanical plating, and plastic coating.
Galvanizing Type Description
Hot-dip galvanizing is currently considered to be one of the best ways to galvanize steel pipes due to its durability and corrosion resistance. The method involves immersing the metal into a bath of molten zinc in 450 degrees Fahrenheit. This process is completed when the steel tube (or EN (Euro Norm) or ASTM (American Society for Testing and Materials)) standard material is coated with approximately 30 to 40 microns of pure zinc.
Electroplating is another popular way to galvanize steel tubes due to its high-quality finish and relatively cheap cost compared to other methods such as hot-dip galvanization. Electroplating uses electrical currents in order to deposit a thin layer of chromium, nickel or zinc on top of an already existing metal surface.
Mechanical plating, also called mechanical polishing, is a low-cost alternative that involves adding a thin layer of zinc using an abrasive blasting (shot peening) method. This type of galvanizing process is not as popular due to its lower quality finish and tendency to flake or peel off.
Plastic coating is the least-used method for galvanizing steel tubes since it has limited functionality and poor corrosion resistance.
