Metallizing TSA

A painted coating is not the only way to protect steel. A thin layer of pure aluminium, zinc or a metal alloy could also be used. Metallizing offers protection for a period of up to 50 years.


By applying a passive fire protection coating, a steel construction can withstand high temperatures for a longer period of time, allowing for a safe evacuation.

Pre-treatment and protection

Before a corrosion resistant coating can be applied to an object, the surface first has to undergo pre-treatment to improve bonding. Various techniques are available for both the pre-treatment process and the application of a protective coating:

Each method affords specific possibilities and advantages. We will gladly assist you in making the right choice.


Spraying is the most commonly used method for the application of protective coatings.


Blasting involves forcible propelling or spraying a stream of abrasive material, such as sand, grit or soda, against a surface under high pressure, thus removing rust, contaminants, mill scale and old layers of paint.

If this isn’t a truly Dutch assignment, we don’t know what is! We’ve been assigned to coat this Y-Pylon by Van der Zalm Metaalindustrie BV. It will be used to support a bicycle bridge at the Bleiswijkseweg. We’ve also applied a special anti-graffiti layer, to protect it from ‘art’ by the locals.
