1.0 EXECUTIVE OVERVIEW

SEA LION International Trade Co., Ltd. presents a targeted solution for fleet managers and construction enterprises operating in high-stress environments: professionally refurbished heavy-duty truck platforms (market-referenced as “Lafayette” inventory). This report details the operational and economic rationale for integrating these platforms into mining haulage, bulk logistics, and large-scale construction fleets across Africa, Russia, and Southeast Asia.

The core challenge for operators in these regions is sustaining equipment availability under extreme conditions (dust, humidity, sub-zero temperatures, poor infrastructure) while managing total cost of ownership (TCO). New OEM trucks often present prohibitive capital expenditure and complex supply chain dependencies. SEA LION’s curated inventory of SINOTRUK, SHACMAN, and XCMG-derived platforms—subjected to rigorous 180-point industrial refurbishment—delivers a validated alternative. These units achieve >92% operational readiness within 72 hours of deployment, directly addressing downtime costs averaging $1,200–$2,500/hour in mining/construction stoppages (Source: ICMM 2025 Benchmark).

Key Value Propositions:

• TCO Reduction: 35–50% lower acquisition cost vs. new equivalents, with maintenance costs aligned to new-unit schedules due to full-system refurbishment.
• Environmental Resilience: Engineered for regional extremes (e.g., -40°C cold-start certification for Russian operations; IP67-rated electrical systems for African dust).
• Supply Chain Integrity: Direct OEM parts access eliminates 3rd-party reliability risks; global logistics network ensures <14-day parts delivery to 95% of target regions.

3. Corrosion Protection: Wax Spraying Treatment

Seawater exposure during maritime transport poses a significant risk of corrosion to undercarriages, chassis frames, and engine compartments—especially in tropical and high-humidity routes.

Recommended Protection Protocol:

• Application: Full underbody and chassis wax spraying using industrial-grade, salt-resistant polymer wax.
• Thickness: Minimum 25–30 microns dry film thickness.
• Coverage Areas: Frame rails, suspension components, fuel tanks, brake lines, and exhaust systems.
• Durability: Effective for up to 6 months in marine environments.
• Removal: Non-toxic, biodegradable formula; easily removed with industrial degreasers post-delivery.

Benefits:

• Reduces saltwater-induced pitting by up to 85%.
• Preserves resale value and structural integrity.
• Complies with ISO 9223 corrosion protection standards.

Note: Wax treatment is strongly advised for Flat Rack and Bulk Cargo shipments due to prolonged exposure. RO-RO units benefit from partial protection but still require treatment for long-haul routes (>30 days).
