Galvanizing is the process of adding a zinc coating to the surface of steel or iron. Since the zinc acts as a sacrificial coating, it protects the steel or iron underneath, thus extending the life of the metal component. But galvanizing is a complex process that can be performed in a variety of ways. Different forms of galvanizing exist, including hot-dip galvanizing and thermal diffusion galvanizing, and each of these variations has advantages and disadvantages. Therefore, it is helpful to understand the different forms of galvanizing before incorporating it into your prototyping or manufacturing project. Galvanized metal is more common than you think. Structures such as building frames, metal benches, balconies, ladders, and fire escapes can all be made of galvanized metal to ensure a longer life and adequate protection from corrosion and damage. Other examples can be found in automotive parts and appliances. In addition, galvanized steel and galvanized iron can be used in different manufacturing processes, from sheet metal processing to CNC machining, making it a staple process in the manufacturing industry.
