Thermal Spray Aluminium (TSA) Coating: A Simple Guide
What is Thermal Spray Aluminium (TSA) Coating?
Thermal Spray Aluminium (TSA) is a protective coating technique used to prevent corrosion on metal surfaces. It involves spraying molten or semi-molten aluminium onto a surface to create a protective layer. This process extends the lifespan of metal structures, especially those exposed to harsh environments like marine, offshore, and industrial settings.
Why is TSA Coating Important?
Metal structures, especially steel, are prone to corrosion when exposed to moisture, salt, and chemicals. TSA coating provides a strong and long-lasting protective barrier that prevents rust and degradation. It is widely used in industries such as oil and gas, marine, power plants, and infrastructure development.

How Does TSA Coating Work?
TSA coating is applied using a thermal spray process, which includes the following steps:
Surface Preparation – The metal surface is cleaned and roughened using abrasive blasting to ensure good adhesion of the coating.
Aluminium Spraying – Molten aluminium is sprayed onto the surface using a thermal spray gun, which melts the aluminium wire or powder and propels it onto the surface.
Coating Formation – The sprayed aluminium particles cool and bond to form a dense and uniform protective layer.
Sealing and Finishing – A sealant may be applied to enhance protection and durability.
Benefits of TSA Coating
Excellent Corrosion Protection – TSA coatings provide long-term resistance against corrosion, even in extreme environments.
Durability – With proper application, TSA coatings can last for decades with minimal maintenance.
Heat Resistance – TSA-coated surfaces withstand high temperatures, making them ideal for industrial applications.
Eco-Friendly – TSA coatings reduce the need for frequent repainting and chemical treatments, lowering environmental impact.
Cost-Effective – Although the initial application cost may be high, TSA coating significantly reduces maintenance and repair expenses over time.
Where is TSA Coating Used?
TSA coatings are widely used in:
Oil and Gas Industry – Protection of pipelines, storage tanks, and offshore structures.
Marine Industry – Coating of ship hulls, decks, and port equipment.
Bridges and Infrastructure – Protection against weathering and pollution.
Power Plants – Coating of turbines, boilers, and heat exchangers.
Conclusion
Thermal Spray Aluminium (TSA) coating is a highly effective method to protect metal surfaces from corrosion, ensuring durability and cost savings. Its applications span various industries, making it a preferred choice for long-term asset protection. If you need a reliable, long-lasting solution for metal preservation, TSA coating is an excellent option.
