Galva Coat Industries Hot Dip Galvanizing Process

Hot Dip Galvanizing is a reliable and long-lasting method that enhances the durability and protection of steel products. This time-tested process follows carefully controlled steps to ensure consistent quality and strong corrosion resistance. Its reliability makes it ideal for many industrial and construction applications.

1. Cleaning Cycle:
   The galvanizing process begins with a multi-step cleaning cycle. This process includes degreasing to remove oil and grease, followed by rinsing to clear residues. Pickling eliminates rust and scale, and a second rinse completes the cleaning cycle. These steps thoroughly prepare the steel surface by removing contaminants that could affect the zinc-to-steel bond. Proper cleaning plays a critical role in the overall success and effectiveness of the galvanizing process.
2. Fluxing:
   After cleaning, the steel enters the fluxing phase. This key step in the Hot Dip Galvanizing process adds a protective layer that removes residual oxides. It also prevents new oxidation from forming. The flux ensures the steel is properly conditioned before immersion in molten zinc. This preparation supports efficient coating formation and reduces material waste.
3. Galvanizing:
   At the heart of the Hot Dip Galvanizing process is the zinc bath. We immerse the steel into molten zinc maintained at approximately 840°F (449°C). The zinc chemically reacts with the steel’s surface to form a strong zinc/iron alloy. This metallurgical bond creates a protective layer that shields the steel from moisture, oxidation, and other corrosive elements. The result is a highly durable and maintenance-free coating ideal for demanding environments.
4. Post-Treatment:
   After galvanizing, we perform post-treatment steps such as quenching and passivation. These treatments help improve the surface appearance, reduce the risk of white rust, and add another layer of protection. The final product offers a uniform, attractive finish ready for immediate use or storage.
