Ultraplate Coating

The Ultraplate coating was especially developed for the offshore industry to withstand the extremely corrosive saltwater environment . This coating is suitable to protect carbon steel, working in submerged saltwater conditions or in the splash zone. Additional advantages of Ultraplate are an extremely high adhesion to the rod material, excellent wear properties as well as the possibility to repair partial damage of the coating locally.
