Key Points For Rust Prevention Treatment Of Truck Export By Sea Freight To Avoid Rust And Loss Upon Arrival At The Port

The long sea voyage and large temperature difference in the cabin of African shipping can easily cause extensive rusting of the frame, chassis, and hydraulic components due to salt spray and high humidity. This not only affects the appearance of the vehicle, but also exacerbates brake and suspension failures, increasing the cost of on-site maintenance for customers. This article outlines the complete set of standardized anti rust treatment processes for exporting African trucks, helping foreign trade practitioners avoid the risk of maritime corrosion.
Cleaning the entire vehicle before loading is the foundation of rust prevention, which requires high-pressure flushing of the chassis, wheels, and suspension gaps for sediment and impurities. After complete drying, the anti-corrosion process can be carried out to avoid moisture sealing and the formation of hidden rust inside the components. Exposed metal parts are treated with layered anti-corrosion, and the frame, steel plate springs, axle, and screws are all coated with thick anti rust butter; Spray special marine anti rust wax on hydraulic piston rods of dump trucks and pump trucks to isolate salt spray erosion; Apply rust proof grease to small metal points such as exhaust and brake pipe joints, wheel hub bolts, etc. one by one, leaving no blind spots for protection.
The whole vehicle is sprayed with thickened marine anti rust wax, and the chassis, beams, wheel arches, and other easily corroded areas are sprayed with 2 to 3 layers to form a waterproof and salt spray protective film. The electrical system is individually protected by disconnecting the vehicle's main power supply, wrapping the battery electrodes with VCI vapor phase rust proof film, and sealing the wiring harness joints to prevent moisture short circuits and metal terminal oxidation. The rearview mirror, headlights, and driver's cabin glass are fully covered with thick waterproof protective film to prevent salt spray corrosion of the paint surface and whitening of the lighting fixtures.
Simultaneously strengthen moisture-proof protection during the packing process, evenly place sufficient desiccants inside the container, and monitor the humidity inside the cabin with a humidity indicator card; The overall exterior of the vehicle is covered with a waterproof and wear-resistant protective film, and a soft cushion is installed at the position where the fixed rope contacts the vehicle body to prevent the anti rust coating from being worn out. When transporting large items on a roll on/roll off ship, an additional layer of anti rust wax is added to the chassis for reinforcement. The salt spray erosion in the open cargo hold is stronger, and the protection standard needs to be higher than that of container transport vehicles.
After shipment, there are two details that are easily overlooked: draining the accumulated water in the gas storage cylinder to prevent rusting of the internal pipe wall; Seal the gaps between the tires and chassis to reduce the accumulation of condensation water in the cabin. After the vehicle arrives at an African port, the customer needs to rinse the entire chassis with clean water within 48 hours to remove salt deposits, and then perform a simple waxing maintenance to extend the service life of the vehicle chassis for a long time.
A comprehensive maritime rust prevention process can significantly reduce the probability of truck rusting upon arrival at the port. Manufacturers can provide standardized anti-corrosion packaging services based on transportation routes, and deliver rust prevention and maintenance instructions to overseas customers simultaneously, protecting vehicles from factory to landing and reducing after-sales disputes.
