Spray Aluminising: High-Performance Coating for Corrosion Resistance

Spray aluminising is a protective metal coating process that applies a layer of pure aluminium onto steel surfaces using thermal spray technology. This method creates a strong, long-lasting shield against rust, oxidation, and extreme temperatures—making it ideal for industries exposed to harsh environments.

During the process, aluminium is melted through a controlled flame or electric arc, then sprayed onto a cleaned metal surface. As it cools, it forms a uniform metallic layer that offers excellent corrosion resistance and thermal protection, even in marine or chemical zones.

🔧 Why Industries Choose Spray Aluminising

Exceptional protection against saltwater, humidity, and industrial gases

Withstands high temperatures without degrading

Acts as a sacrificial layer, prolonging the life of metal structures

Can be easily overcoated with paint for added durability and finish

Suitable for complex shapes and large structures

🏭 Common Applications

Offshore platforms and marine equipment

Refineries, boilers, and power plant structures

Steel bridges, towers, and pipelines

Industrial chimneys and storage tanks

📈 Boost Your Asset Lifespan with Spray Aluminising

For sectors where corrosion is a constant challenge, spray aluminising delivers a reliable solution that reduces maintenance costs and extends structural life. It’s an environmentally responsible and efficient alternative to hot-dip galvanizing or traditional painting.

Conclusion

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.
