What is Spray Galvanizing?

Spray galvanizing is a cold process in which zinc wire or zinc powder is melted using a flame or electric arc and sprayed onto the surface of a metal object using compressed air. This forms a strong, corrosion-resistant zinc coating that bonds tightly to the surface, acting as a barrier against rust and moisture.

Unlike hot-dip galvanizing, spray galvanizing doesn’t require dipping the entire component into molten zinc. This makes it ideal for large, fixed, or heat-sensitive structures, such as bridges, tanks, pipelines, towers, and industrial equipment.

Benefits of Spray Galvanizing

 Excellent Corrosion Resistance

Spray galvanizing offers superior protection against rust, saltwater, chemicals, and weather exposure. It is especially useful in marine, coastal, and industrial environments.

 Cold Application Process

Since it’s a cold spray method, there’s no risk of heat distortion to the metal. This makes it perfect for thin steel sections, structural components, or assembled items that cannot be hot-dipped.

On-Site Application

One major advantage of spray galvanizing is that it can be done directly on-site. You don’t need to dismantle or transport large structures, reducing downtime and labor costs.

 Adhesion to Complex Shapes

Spray galvanizing can coat irregular shapes and hard-to-reach areas effectively, ensuring full coverage and protection across the entire surface.

Paintable Surface

Zinc-coated surfaces can be painted or powder coated after application, allowing for both functional and decorative finishes. This combination, often called a duplex system, further improves corrosion resistance.

Common Applications of Spray Galvanizing

Spray galvanizing is widely used across multiple industries, including:

Oil and Gas – For protecting offshore rigs, pipelines, and refineries from harsh weather and salt exposure.

Infrastructure – Applied on bridges, guardrails, towers, and structural steel for long-term durability.

Marine Industry – Used on ships, docks, and metal parts exposed to seawater.

Manufacturing – Applied to industrial machinery, parts, and fabricated steel.

Utilities – For poles, transformers, and power infrastructure needing corrosion resistance.

Conclusion

Spray galvanizing is a smart, flexible, and reliable method for extending the lifespan of metal structures and components. It offers excellent corrosion resistance, easy on-site application, and versatility across a range of industries. Whether you're protecting new construction or maintaining aging infrastructure, spray galvanizing is a cost-effective solution for long-term performance.

If you're looking to protect your metal assets with high-quality zinc coating, consider spray galvanizing as your go-to method for durability and peace of mind.

Mythri Metallizing India 

Mythri Metallizing India, headquartered in Bangalore, is a thermal spray coating service provider that specializes in anti-corrosion solutions for steel structures. They have over 20 years of experience in the industry. https://mythrimetallizing.com/

Services: Mythri Metallizing India offers a range of surface finishing and anti-corrosion services, including:

Sandblasting and grit blasting

Spray galvanizing

Stress relieving

Spray painting

Thermal spray aluminum coating

Surface Preparation: Mythri Metallizing uses abrasive blasting techniques, employing materials like grit, sand, quartz, and aluminum oxide, to clean and prepare metal surfaces for coating. This process removes mill scale, oil, grease, dirt, rust, oxides, and paint to ensure proper adhesion of protective coatings.

Thermal Spraying: Mythri Metallizing applies finely divided metallic or nonmetallic materials in a molten or semi-molten state to form a coating, using methods such as electric arc spray, wire flame spray, powder flame spray, HVOF, and plasma spray.  https://mythrimetallizing.com/

 Zinc coatings are used to protect steel, even at cut edges or breaks, through sacrificial action.

Stress Relieving: Mythri Metallizing uses heat treatment to improve machining, formability, and ductility, enhancing product performance by increasing strength and other desirable characteristics. https://mythrimetallizing.com/

The spray galvanizing techniques at Mythri adhere to national and international standards applied as a corrosion protection restoration to damaged sections of any steel component. Once we complete the sandblasting services in Bangalore, we can go either for spray painting or for the spray galvanizing with zinc, or Alluminium, or copper coating. Mythri metallizing provides the Spray galvanizing service in Bangalore.
