Hot dip galvanizing is a protective coating process in which steel or iron is immersed in a bath of molten zinc at around 450°C (840°F). This process creates a strong, corrosion-resistant layer that bonds metallurgically to the base metal, protecting it from rust, moisture, and environmental damage.
Steel is cleaned using an alkaline or acidic solution to eliminate dirt, oil, grease, and industrial residues. This step ensures the surface is perfectly clean for the next chemical treatment
Steel is rinsed with clean water to remove any remaining cleaning agents, preventing interference with the pickling process.
The steel is immersed in acid to remove rust, scale, and oxidation.This exposes clean, bare steel for better zinc adhesion during galvanizing.
A thorough rinse removes all acid traces and contaminants to prevent weakening of the zinc coating.
Steel is dipped into a zinc ammonium chloride flux solution. This removes any last traces of oxides and coats the steel with a protective layer that prevents oxidation before galvanizing.
Steel is heated to remove all moisture and prepare the surface for immersion in molten zinc. This step reduces splashing and improves coating uniformity.
Steel is submerged in a bath of molten zinc (around 450°C). A metallurgical reaction occurs, forming multiple zinc-iron alloy layers for long-term corrosion protection.
Once removed from the zinc bath, steel is cooled by air or water to solidify the zinc coating and make handling safe.
A thin protective chemical layer is applied to prevent white rust and protect the zinc finish during storage and transport.
The galvanized steel is checked for coating thickness, adhesion, surface finish, and defects. Any irregularities are corrected before dispatch.
