We are not just pioneers in galvanizing chemicals—we also offer state-of-the-art hot-dip galvanizing services to ensure superior corrosion protection for steel structures and components. With a commitment to quality, we deliver durable, long-lasting coatings that meet industry standards.
Degreasing is the first step in the hot dip galvanizing process. The steel is dipped in an acidic bath, any oil, grease, dirt, or other contaminants on the steel’s surface are removed.
Pickling removes rust, scale, and oxidation from the steel’s surface. The steel is dipped in a diluted acid bath, which cleans off any remaining impurities, preparing it for the zinc coating.
Fluxing is the final cleaning step before galvanizing. The steel is dipped in a flux solution that prevents oxidation and helps the zinc bond better with the steel. Without this step, the zinc coating can be uneven or weak.
Zinc Bath: This is the core step of the hot dip galvanizing process. In this stage, the cleaned and fluxed steel is dipped into a bath of molten zinc heated to around 450°C (840°F). This creates a tough, corrosion-resistant coating that protects the steel from rust and damage.
The passivation step in hot dip galvanizing is the final treatment that protects the freshly galvanized steel from white rust (zinc oxidation) during storage and transport. After the zinc coating cools, the steel is dipped in a passivation solution
