Coating systems and corrosion category selection for wind turbine fasteners and clamps — from hot-dip galvanizing for onshore tower bolts to Geomet and duplex stainless for offshore C5-M environments.
HDG vs Geomet/Dacromet Zn-Al flake coatings for wind turbine fasteners — corrosion protection, thread fit, grade compatibility, and when offshore projects require flake coatings.
What Geomet and Dacromet zinc-flake coatings are, how they differ, why they are specified for high-strength and offshore wind bolts, and how they compare with hot-dip galvanizing.
Galvanic corrosion in wind turbine fasteners: galvanic series, material pairing rules, insulating solutions, and coating strategies for onshore and offshore applications.
How the ISO 12944 / ISO 9223 corrosion categories C1 to CX work, which category onshore and offshore wind sites fall into, and how to match fastener coating and material to each.
