Who We Are

Metallization | TSA

TSA (Thermal Sprayed Aluminum) is by far the most sustainable method for preservation/anti-corrosion, wear or anti-slip treatment of all (base) metals. 

Using compressed air, gas and oxygen, aluminum or zinc wire (or a combination) is sprayed in molten state with a metallizing gun onto a (pre-blasted) metal surface.

The sprayed aluminum layer – of at least 250 microns – solidifies immediately and thus forms a corrosion-resistant protective layer. This layer provides protection from corrosion for at least 30 years.

It is also possible to apply a TSA layer directly under the insulation, so that the risk of CUI (Corrosion Under Insulation) is significantly reduced.

The importance of


Metallization provides steel structures of any size with significantly longer protection against all forms of corrosion.

This protection benefits process safety and minimizes maintenance costs: Objects last longer and require much less maintenance.

Where with usual (paint) coatings the protective layer needs to be redone after 4 to 5 years, metallizing provides your steel with protection for at least 30 years.


The benefits for your project:

● Optimal protection against corrosion

● Protection period of at least 30 years (also under tough conditions)

● No drying or curing time

● Significant cost savings on maintenance

● Objects last longer.

● Better quality and a more durable choice compared to only paint coatings

● No downtime during work process

● Fire safe result

● Time saving compared to other coating processes.
