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.
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.
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.
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.
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.
