4. Corrosion Protection: Wax Spraying System
4.1. Seawater Corrosion Risk
Extended marine transit exposes metal surfaces (chassis, suspension, undercarriage) to salt-laden air and condensation. Unprotected steel components may develop surface oxidation within 7–10 days at sea.
4.2. Recommended Protection: Industrial Wax Spray Coating
SEA LION International mandates the application of synthetic hydrophobic wax emulsion prior to shipment for all HOWO units.
Application Protocol:
- Surface Prep: Degrease and dry undercarriage, wheel arches, frame rails.
- Spray Method: High-pressure airless spray (3–5 mil thickness).
- Coverage Areas:
- Chassis frame (full length)
- Suspension components (U-bolts, shackles)
- Fuel/water tanks (underside)
- Axle housings and brake chambers
- Drying Time: 4–6 hours at 25°C ambient.
- Duration of Protection: Up to 120 days at sea under ISO 9223 corrosivity class C5-M.
Performance Metrics:
| Property | Value |
|---|---|
| Salt Spray Resistance (ASTM B117) | >1,000 hours no red rust |
| Adhesion (Cross-hatch, ISO 2409) | Class 0 (no flaking) |
| Temperature Range | -30°C to +80°C |
| Removability | Biodegradable solvent or hot wash |
Note: Wax must be removed upon delivery before commissioning.
5. Method Recommendation by Use Case
| Scenario | Recommended Method | Rationale |
|---|---|---|
| Fleet Delivery (>50 units), Stable Ports | RO-RO | Lowest damage risk, fastest turnaround, best cost/unit at scale. Requires RO-RO-capable destination. |
| Remote Sites, No RO-RO Facilities | Bulk Cargo | Balanced cost and accessibility. Requires robust lashing and wax protection. |
| Oversized or Modified Trucks | Flat Rack | Only viable option for non-standard configurations. Highest exposure risk—wax spray mandatory. |
6. Operational Best Practices
- Pre-shipment Inspection: Confirm fuel tanks <1/4 full, batteries disconnected, tire pressure adjusted.
- Lashing (Bulk & Flat Rack): Use ISO-compliant lashing chains (min. 2,500 kg SWL) at 4–6 anchor points per unit.
- Documentation: Provide CMR, Packing List, and Corrosion Protection Certificate with each shipment.
- Port Coordination: Pre-book RO-RO berths 14 days in advance; bulk loads require 7-day crane scheduling.
7. Conclusion
For large-scale export of HOWO 6×4 dump trucks from China, RO-RO shipping offers optimal efficiency and protection, provided destination ports support vehicle roll-off operations. Where infrastructure is limited, Bulk Cargo with full wax spraying presents a cost-effective alternative. Flat Rack remains a niche solution for modified units but demands stringent corrosion control.
All shipments must include industrial wax-based anti-corrosion treatment to ensure operational readiness upon arrival, minimizing post-delivery rework and warranty claims.
