What is Hot Dip Galvanizing

What is Hot Dip Galvanizing?

Hot Dip Galvanizing (HDG) is a corrosion protection process in which cleaned steel components are immersed in molten zinc maintained at approximately 440°C to 460°C. During immersion, zinc reacts metallurgically with the steel surface to form multiple protective alloy layers.

Unlike paint or conventional coatings that only cover the surface, Hot Dip Galvanizing forms a strong metallurgical bond that provides complete and long-lasting protection, even in demanding outdoor and industrial environments.

Metallurgically bonded zinc coating for durable protection.
Complete coverage suited to demanding outdoor environments.
Protection against rust, moisture, chemicals and exposure.
Long-lasting corrosion resistance compared with surface-only coatings.

Our Hot Dip Galvanizing Process

Our galvanizing process follows carefully controlled stages to ensure uniform coating quality and dependable corrosion protection.

Degreasing

Steel components are cleaned to remove oil, grease, dirt, and surface contaminants.

Pickling

Rust, mill scale, and surface oxides are removed using acid treatment.

Rinsing

Components are rinsed thoroughly to eliminate residual chemicals.

Fluxing

A flux solution is applied to prevent oxidation before galvanizing.

Drying

Components are dried before entering the molten zinc bath.

Hot Dip Galvanizing

The prepared steel is immersed in molten zinc, creating a durable metallurgical bond between steel and zinc.

Cooling & Quality Inspection

Galvanized components are cooled, inspected, and prepared for dispatch.
