coatings
Maximum corrosion, wear and chemical protection, lower total cost of ownership, and unbeatable reliability.
Unmatched cylinder
piston rod protection.
90% of hydraulic cylinder failure is a result of inferior piston rod coatings. But with Griekspoor, you’re protected. TOPCOAT are the highest quality coatings available — maximizing the lifespan of equipment in the world’s most challenging conditions.
Our coatings are extremely wear-resistant and corrosion-resistant, that is finished to the specified fit and roughness. We coat products up to a length of 23 meters, a diameter of 1100 millimeters and a weight of 20 tonnes.
TOPCOAT delivers:
- Hard chrome and nickel chrome replacement, freeof chromium 6
- Maximum lifetime and reliability in heaviestfields
- Surface rougness finished to customer requirements
- Minimum wear of seals and scrapers
- Upgraded base material upgrade by applyingTOPCOAT

Tough protection for tough conditions — NBD 10300
Every TOPCOAT-system is engineered to meet and surpass the latest NBD 10300 requirements — the Dutch national standard for high-performance (ceramic) hydraulic rod coatings in demanding waterway environments.
Remanufacturing program
Our remanufacturing program restores used or damaged piston rods to as-new condition, backed by the full Griekspoor TOPCOAT warranty.
Every rod entering our facility undergoes a complete rebuild process:
- Removal of the old (chromium) coating
- Inspection and analysis of the base material
- In-house or partner-assisted repair of wear, corrosion or thread damage
- Application of a new TOPCOAT-system, produced under the same strict quality and testing standards as new rods
The result is a component that performs like new: faster, more sustainable and significantly more cost-efficient than replacement. You retain your critical cylinder–rod pairing, reduce global metal consumption, and extend the life of your equipment through a fully circular solution.
