Tropical Marine Anti-Corrosion Skeletal Trailer
The Tropical Marine Anti-Corrosion Skeletal Trailer is a specialized, high-durability intermodal transport chassis engineered explicitly to withstand aggressive salt-spray corrosion, high humidity, and tropical coastal wharf environments. Treated with a rigorous multi-layer marine-grade coating system—including zinc-rich epoxy primers, high-build epoxy intermediate layers, and anti-ultraviolet polyurethane topcoats—it offers exceptional cathodic protection and rust prevention. Fabricated using high-tensile Q345B/Q550 structural steel and automated submerged-arc welding, it delivers supreme structural integrity and extended service life in severe marine atmospheres. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Marine-Grade Anti-Corrosion Chassis Architecture
- High-Tensile Steel Construction: Fabricated using Q345B or Q550 high-tensile structural steel plates, designed with sealed box profiles and crevice-free welding to eliminate moisture-trapping pockets.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees absolute structural joint integrity and continuous, pin-hole-free weld seams.
- Surface Preparation (SA2.5 Blast Cleaning): Complete structural steel frame undergoes abrasive blast cleaning to ISO 8501-1 SA2.5 standard, completely removing mill scale, rust, and surface impurities to ensure maximum paint adhesion.
- Multi-Layer Marine Coating System: Coated with a high-performance zinc-rich epoxy primer (providing active cathodic protection), followed by an epoxy high-build intermediate coat, and sealed with an ultra-violet-resistant marine-grade polyurethane topcoat.
- Corrosion-Resistant Hardware: Equipped with stainless steel or hot-dip galvanized fasteners, hinge pins, twist-lock handles, and component fittings to prevent galvanic corrosion in coastal zones.
2. Axle, Suspension & Pneumatic Braking Systems
- Marine-Protected Axles: 2 or 3 heavy-duty axles (FUWA, BPW, or equivalent premium brands; 13T / 16T capacity per axle) featuring marine-sealed waterproof wheel-end bearings and anti-corrosion brake dust shields.
- Suspension Options: Multi-leaf spring suspension or balanced air suspension systems treated with anti-corrosion protective coatings.
- Tire & Rim Setup: 8 to 12 heavy-duty commercial tires paired with corrosion-resistant painted high-load steel rims.
- Pneumatic Braking System: Advanced dual-line pneumatic braking system featuring brass/composite fittings, quick-release valves, and full ABS compliance ensuring reliable stopping performance in humid conditions.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: 28-Ton two-speed heavy landing gear (JOST / FUWA) with anti-corrosion treated outer housings and standard 50# (2") or 90# (3.5") interchangeable kingpins.
- Electrical & Lighting System: 24V 7-pin LED lighting system featuring fully sealed, resin-potted waterproof wiring harnesses and corrosion-resistant plug connectors.
- Standard Utility Add-ons: Hot-dip galvanized spare tire carriers, heavy-duty marine-grade mudguards with anti-spray flaps, and a lockable weather-sealed aluminum/steel tool box.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main beam structure and anti-corrosion paint performance; 1-Year warranty for axles, suspension, and electrical components.
- Delivery Lead Time: 25 – 35 working days upon order confirmation.
- Packaging & Shipping: Nude packing; stacked or shipped via Ro-Ro vessel, Bulk Cargo ship, or Container.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
