Griekspoor TOPCOAT,
the number 1 to
minimize corrosion
on hydraulic systems.

Corrosion is eating into productivity, and your profits.

As a long-term offshore partner, we know the energy industry is where uptime and reliability are really key. Corrosion is one of the biggest challenges in today’s industry. Corrosion damage costs the global economy up to 2.5 trillion annually (NACE International).

The problem is not even the loss of the material or failing hydraulic cylinders itself. The major effect comes from the impact on delayed schedules and energy system downtime.

corrosion resistance.
Mainly down
to two factors.

Corrosion is the single biggest reason why hydraulic cylinders fail in today’s offshore energy industry. To minimize corrosion damage, and thus downtime, the problem can be divided into two parts. The coating material matrix and the quality of the flame spraying application.

TOPCOAT 107+: corrosion resistance to a whole new level

Scientifically superior hydraulic cylinder protection by Griekspoor Thermal Coatings. TOPCOAT coatings are warranted to resist corrosion, abrasion, and thermal deterioration — reducing unscheduled maintenance and costly downtime.

TOPCOAT 107+, the flagship coating for our offshore clients worldwide, specially developed for the most severe conditions on earth. Standardized electrochemical porosity tests and polarization curve testing, both performed in-house, ensure the highest quality of coating and the best corrosion resistance.

Quality of the process - ROI on the long-term

The quality of the coating process is the final touch in remarkable achievements, which pay off easily in the long-term. Our coating process goes from careful preparation, over the coating process itself, up to tuned finishing and testing.

To prevent every single mistake we meticulously monitor the coating process and continuously test every single production step before taking the next step. This results in far better coatings than the industry standard.

Civil
engineering
since 1968.

90% of hydraulic cylinder failure is a result of inferior rod coatings. But with Griekspoor, you’re protected.

Griekspoor Thermal Coatings, a Dutch family business since 1968, maximizes the reliability and lifespan of your fleet in the world’s most challenging conditions. TOPCOAT coatings are engineered to deliver constant, long lasting protection against sea-fouling, chemical damage, heat and abrasion to keep you up and running in the most demanding operating environments on earth. Ensuring tight offshore platforms schedules are kept, and our clients investment in offshore (renewable) energy is secure.

Proud strategic partnership

Griekspoor and main seal supplier Freudenberg, in partnership, have conducted three full years of testing to further improve TOPCOAT coatings, extend lifetime of both seals and coating and ensure minimum roughness change over time under worst-case conditions.

“All kinds of coating/seal combinations have been tested over more than 10.000kms. The results are really groundbreaking for both parties and we are convinced that they are also very valuable for the offshore industry. It helps us give valuable information to our clients in realizing the industry’s ambitions.”
