| Drying Time | 4 hours at 25°C (RH < 60%) |
| Salt Spray Resistance | ≥ 500 hours (ASTM B117) |
| Post-Transit Removal | Biodegradable citrus-based solvent (non-toxic) |
Benefits:
– Prevents chloride-induced pitting on high-tensile steel.
– Reduces field warranty claims by up to 68% (based on 2025 SEA LION field data).
– Compatible with all three shipping methods—mandatory for Bulk Cargo, recommended for RO-RO and Flat Rack.
4. Recommended Shipping Strategy
| Factor | Recommended Method | Rationale |
|---|---|---|
| High-Volume Export | Flat Rack Container | Optimal balance of protection, tracking, and scalability. |
| Time-Sensitive Delivery | RO-RO | Faster port turnaround; ideal for JIT construction deployments. |
| Budget-Constrained | Bulk Cargo (with wax + insurance) | Lower base cost, but requires full anti-corrosion treatment and risk mitigation. |
Critical Recommendation: For all methods, integrate wax spraying into final assembly line. Pre-treatment reduces rework and ensures uniform coverage.
5. Conclusion
For fleet managers and construction firms deploying the XE-15E globally, Flat Rack containerization offers the most reliable and scalable solution, particularly when combined with industrial wax protection. RO-RO remains viable for rapid deployment to RO-RO-enabled regions, while Bulk Cargo is discouraged unless cost is the overriding factor and full corrosion protection is implemented.
SEA LION International confirms that adherence to wax spraying protocols reduces post-import maintenance costs by an average of 41% across 12 global markets.
