Steel Preservation

1. Inspection and advice

Every preservation process starts with a thorough inspection. We assess, among other things:

• The current condition of the steel structure
• The mechanical load (e.g., vibrations or traffic load)
• Environmental factors, such as indoor or outdoor environment, atmospheric load (moisture, UV, air pollution) and contact with chemicals or marine climate

Based on this, we recommend a preservation system that complies with the NEN-EN-ISO 12944 standard and fits the desired lifespan.

2. Surface treatment

Effective preservation begins with proper surface treatment of steel. Depending on the object and location, we apply techniques including steel blasting. This technique removes old layers and contaminants and creates a rough surface for optimal adhesion. Chemical pre-treatments such as zinc phosphating and passivation are also among the possibilities.

3. Application of preservation systems

After pre-treatment, we apply the chosen preservation system. This can consist of one or more layers of coating, ranging from primers to final finishes. We use solvent-free coatings, hot-spray techniques, and where necessary, fire-resistant systems to make steel fire-resistant. Layer thickness and adhesion are continuously monitored. Our quality assurance is guaranteed by NACE-certified inspectors.

On-site

Thanks to our mobile equipment, we can preserve steel at any location in the Netherlands. Our mobile preservation units are equipped with:

• Mobile blasting and spraying equipment
• Metallizing installations (including Thermal Sprayed Aluminium)
• Extraction and filter units (including dust reduction and ventilation)
• Power generators
• Lighting and communication equipment

This makes steel preservation possible in operational environments such as hospitals or factories, without prolonged downtime or disruption of processes.

In our Workshops

For projects that benefit from controlled conditions, we have two fully equipped preservation halls in Bergum and Bergharen. Here we perform surface treatment, metallizing, and coating with maximum control over quality, layer thickness, and adhesion. Our halls are suitable for large steel structures and are equipped with advanced spraying and lifting installations.
