| Application Method | High-pressure spray (12–15 bar) |
| Coverage Areas | Frame rails, suspension components, fuel tanks, wheel hubs, radiator supports, electrical conduits |
| Film Thickness | 30–50 µm (uniform coat) |
| Curing Time | 24 hours at 20°C prior to loading |
| Protection Duration | Up to 12 months (seawater immersion tested) |
| Removal | Biodegradable citrus-based solvent (post-delivery) |
Compliance: Meets ASTM B117 Salt Spray Test standards (1,000-hour resistance).
3. Method-Specific Risk Mitigation
RO-RO
- Advantages: Fast loading, reduced mechanical stress, optimal for drivable units.
- Mitigation: Mandatory wax spray + desiccant packs in cab and engine bay.
- Limitation: Restricted to ports with RO-RO infrastructure (e.g., Lagos, Dubai, Santos).
Bulk Cargo
- Advantages: Lower cost, flexible port access.
- Mitigation: Full wax spray + shrink-wrapping of cab and mirrors. Use of timber dunnage to prevent hull contact.
- Limitation: High handling risk; not recommended for premium-condition delivery.
Flat Rack
- Advantages: Accommodates non-standard dimensions.
- Mitigation: Wax spray + full tarpaulin covering (UV-resistant, 600g/m²) + corner protectors.
- Limitation: Extended exposure increases corrosion and cosmetic damage risk.
4. Recommendations
| Scenario | Recommended Method | Rationale |
|---|---|---|
| Exporting 20+ units to RO-RO-capable port | RO-RO | Optimal cost-to-safety ratio, fast turnaround |
| Single or dual units to remote site | Flat Rack | Flexibility outweighs exposure risk |
| Budget-constrained project, moderate volume | Bulk Cargo | Cost-effective with proper protection |
| High-value fleet with OEM finish requirements | RO-RO + Full Wax Spray | Maximum protection and presentation |
5. Conclusion
For fleet managers and construction firms sourcing HOWO dump trucks from China, RO-RO shipping combined with industrial-grade wax spraying delivers the highest reliability and lowest lifecycle maintenance cost post-import. While Bulk Cargo and Flat Rack options offer logistical flexibility, they require enhanced protective measures to prevent saltwater-induced degradation. SEA LION International advises integrating wax corrosion protection as a non-negotiable step in all export workflows, regardless of transport mode.
