Port and offshore equipment combines atmospheric corrosion with constant mechanical damage. Impact from containers, abrasive bulk cargo, wire rope and handling equipment removes coating faster than corrosion ever would, so the specification has to balance corrosion protection with wear resistance — and accept that some areas will need planned touch-up.

Abrasion-resistant coating systems for cranes, spreaders, grabs and deck equipment exposed to impact and salt.
Port machinery and offshore equipment — Abrasion-resistant coating systems for cranes, spreaders, grabs and deck equipment exposed to impact and salt. Service environment: C5-M plus mechanical abrasion; typical design life: 8–15 years. The table below lists the recommended coating build-up and links to the matching product categories and selectable products.

Recommended coating system
| Layer | Type & DFT | Product examples |
|---|---|---|
| Primer | Zinc-rich epoxy, 60–80 µm | Zinc-rich primer |
| Build coat | High-build MIO or glass-flake epoxy, 120–200 µm | MIO / glass-flake epoxy |
| Topcoat | Polyurethane, 60–80 µm; abrasion-resistant on contact zones | PU / abrasion-resistant topcoat |
| High-wear zones | Glass-flake or ceramic-filled coating, thicker build | Abrasion-resistant coating |
Application critical points
- Identify the actual wear zones first — spreader contact points, grab lips, cable runs — and specify them differently from the general structure.
- Abrasion-resistant coatings are not corrosion-resistant coatings. Confirm that the wear layer sits on a properly specified anticorrosive system rather than replacing it.
- Accept planned maintenance on consumable areas and make it easy: keep the same primer across the machine so local repairs match the surrounding system.
