---

4. Corrosion Mitigation: Wax Spraying Protection Protocol

Excavator arms are highly susceptible to saltwater-induced corrosion during marine transport, particularly at weld joints, bearing surfaces, and internal cavities. SEA LION International recommends the following anti-corrosion protocol:

4.1 Wax-Based Protection System

Parameter	Specification
Product Type	Solvent-based, hydrophobic corrosion-inhibiting wax
Application Method	High-pressure spray (2,000–3,500 psi)
Coverage Areas	All external steel surfaces, hinge pins, weld zones, undercarriage contact points
Film Thickness	75–125 µm (dry film)
Salt Spray Resistance (ASTM B117)	>500 hours
Temperature Range	-30°C to +80°C (suitable for global transit)
Removal Method	Biodegradable citrus-based degreaser; high-pressure wash

Implementation: Wax application must occur post-factory cleaning and pre-packaging. Drying time: 2–4 hours in controlled environment (RH <60%).

4.2 Additional Protective Measures

• VCI (Vapor Corrosion Inhibitor) Paper Wrapping: Applied to threaded fittings and bore openings.
• Desiccant Packs: Placed in enclosed cavities (e.g., boom cylinder housing).
• Drainage Plugs: Temporarily sealed to prevent saltwater ingress.

---

5. Recommended Solution

Preferred Method: Flat Rack Container Shipping

Despite higher base cost, Flat Rack offers:
– Maximum structural control and cargo visibility
– Compliance with ISO 1496/2 standards for heavy project cargo
– Compatibility with lashing forces up to 12,000 kgf
– Integration with global intermodal networks (rail, truck, port handling)

Secondary Option: Bulk Cargo (for high-volume, cost-sensitive projects)
Only recommended with:
– Full hull trim optimization
– Dedicated dunnage cradles
– Mandatory wax + VCI treatment

RO-RO: Not Recommended
Unsuitable due to dynamic deck exposure, lack of fixation, and high corrosion/impact risk.

---

6. Operational Workflow (Flat Rack Export)

1. Pre-Treatment: Wax spraying + VCI application at OEM facility (within 24h of final inspection)
2. Loading: Crane lift onto 40’ flat rack with timber dunnage and anti-slip mats
3. Securing: 4-point lashing using 5,000 kg SWL chains with tensioners
4. Documentation: IMDG Class 9 (Miscellaneous Dangerous Goods) if wax is solvent-based
5. Tracking: GPS-enabled container lock with humidity/temperature logging
6. Destination: Direct offload to customer yard or service depot for de-waxing and commissioning

---

7. Conclusion

For reliable, high-integrity export of excavator arms from China, Flat Rack shipping combined with industrial-grade wax corrosion protection represents the optimal logistics solution. This method ensures dimensional stability, minimizes field rework, and extends equipment service life in coastal and humid operating environments.

Bulk Cargo remains a cost-driven alternative under strict packaging and monitoring protocols. RO-RO is unsuitable for non-rolling industrial components and should be excluded from procurement planning.

SEA LION International supports turnkey export packaging and multimodal coordination from Chinese manufacturing zones to global project sites, with full compliance to IACS, CSC, and SOLAS regulations.
