90% of hydraulic cylinder failure is a result of inferior piston coatings. But with Griekspoor, you’re protected. TOPCOAT are the highest quality coatings available — maximizing the lifespan of your equipment in the world’s most challenging conditions.
We have developed a wide range of coating solutions to help you upgrade your systems and to safeguard your machinery. Wherever you’re dredging, even in the most extreme environments, you’re protected.
Griekspoor coatings (TOPCOAT) are engineered to deliver constant, ongoing protection against sea-fouling, chemical damage, heat and abrasion. Our thermal coatings exceed all industry standards and are engineered to keep you up and running in the most demanding operating environments on earth.
TOPCOAT delivers:
As an industry leader metallic surface finishing, our way of working rests on four pillars: Development, application, finishing and testing.
Over the past 50 years, this way of working has allowed us to become the experts in hydraulic cylinder coatings. When you choose Griekspoor Thermal Coatings, you’re not only safeguarding your machinery, you’re protecting your bottom line.
In our mission to meet the needs of the dredging industry, we use HP-HVOF (High Pressure High Velocity Oxygen Fuel) and Plasma Spraying technology to offer a higher level of protection for the exceptionally demanding conditions of today's dredging industry.
TOPCOAT 107 and 107+, Griekspoor’s economical hexavalent chrome free alternatives to nickel chrome plating, show groundbreaking results when testing on corrosion, wear and deformation resistance. Testing in our Extreme Lab and in the field have shown that a HP-HVOF-coated surface has significantly better properties in the tribological system than the previous standards: starting with the high surface hardness and the dense layer structure, through the high wear resistance and durability to a low porosity of less than one percent.
Griekspoor and Freudenberg, in partnership, have conducted three full years of testing to further improve our coatings, extend lifetime and insure minimum roughness change over time. The laboratory process began with rod coatings, finished to varying roughnesses, and resulted in no detectable wear or damage as a result of worst-case situations. And havingtravelled over 6.000kms, over all kinds of Freudenberg seals the roughness values of rod coating were unaffected throughout the entire duration of the test.
Together, let’s create a plan to guarantee you the best protection possible.
Go to contact formLong before the environmental ban on Chromium-6, Griekspoor was working on a
replacement. That research paid off. Our material scientists developed a Chromium-6-free alloy compound and coating process that not only meets industry standards for protection — it exceeds them. Future proof your fleet with Griekspoor Thermal Coatings. Better protection for your business and the planet.
and get to know how we increase productivity and environmental sustainability of today’s dredging industry.
Go to option for hard chrome replacement, also applicable in marine environment at or above sea level. The coating consists of a plasma-sprayed nickel-chrome adhesive layer with a minimum thickness of 100μm and an aluminium oxide/titanium oxide ceramic top layer.

Added chemical resistance when replacing hard chrome plating with Topcoat Ultra. The coating is tribologically similar to the standard TOPCOAT®. The colour is dark grey/green.
Free of chromium 6
Most used for big and heavy piston rods. TOPCOAT® CCR+ consists of a TOPCOAT® 177 UHCR (nickel based superalloy) HVOF sprayed intermediate coating and a chromium carbide top coating, namely TOPCOAT® CCR.
