All Griekspoor coatings are marketed under the trade name TOPCOAT®. All TOPCOAT® coatings meet the demands of the latest version of the NBD 10300, the coating specification for (ceramic) coatings developed and used by the Dutch department of waterways.
"Thermal coatings" are 'hard' coatings. These coatings are thermally applied: with the use of an energy source the coating material is applied to the product. GTC uses plasma, HVOF (High Velocity Oxygen Fuel), and laser as an energy source. This results in a hard coating, extremely wear-resistant and corrosion-resistant, that is finished to the specified fit and roughness. Griekspoor Thermal Coatings coats products up to a length of 23 meters, a diameter of 1 meter, and a weight of 20 tonnes.

*Ceramics is Seals have to be checked. Seal Construction as on page is advised.
** Thicker bond coat equals better corrosion resistance.
*** Thicker if necessary (on request)
