Thermal Spray Aluminium Coating

Thermal Spray Aluminium (TSA) applies a dense, sacrificial aluminium layer onto steel — delivering decades of corrosion protection for marine, offshore, and high-temperature assets, even against Corrosion Under Insulation (CUI).

Wear Resistant Coatings Industrial Surface Engineering Component Life Extension Quality Assured execution

Overview

Thermal Spray Aluminium (TSA) coating provides superior, long-lasting corrosion protection for steel structures. A layer of pure or alloyed aluminium is sprayed onto the prepared surface, forming a tough sacrificial barrier that shields the steel both galvanically and physically. With zero curing time and proven resistance to Corrosion Under Insulation (CUI), TSA is widely specified for offshore platforms, pipelines, pressure vessels, and marine and coastal infrastructure operating in the harshest environments.

Frequently Asked Questions

Thermal Spray Aluminium (TSA) — Common Questions

Answers to common questions about our Thermal Spray Aluminium (TSA) corrosion-protection services.

What is Thermal Spray Aluminium (TSA) coating?
TSA coating is a sprayed layer of pure or alloyed aluminium applied to steel to provide long-term corrosion protection in marine, offshore, and high-temperature environments.
How does TSA protect steel from corrosion?
Aluminium acts as both a barrier and a sacrificial anode, protecting the steel galvanically and physically even if the coating is scratched, with zero curing time.
What is Corrosion Under Insulation (CUI) and how does TSA prevent it?
CUI is hidden corrosion that occurs on insulated pipes and vessels where moisture is trapped. TSA is a proven, long-life solution that prevents CUI on insulated steelwork.
Where is TSA coating typically used?
Offshore platforms, oil and gas pipelines, pressure vessels, marine equipment, and coastal infrastructure exposed to aggressive environments.
How long does TSA coating last?
Properly applied and sealed TSA coatings can protect steel for 20-30 years or more, greatly outlasting conventional paint systems.
