Batch Spraying Of Exported West African Trailers Completed, With Three-layer Anti Corrosion Process Photographed

Recently, a batch of heavy-duty trailers specially designed for the West African market in our factory have completed centralized spraying operations. The full set of three-layer anti-corrosion technology has been synchronously applied, and the entire anti rust process has been photographed in the workshop. This is also the core guarantee for vehicles to adapt to ocean shipping and local humid and hot working conditions.
The climate and environment in the West African market are complex, with high salt spray concentrations in coastal ports such as Lagos, and wet and muddy inland mining areas during the rainy season. Ordinary trailers are prone to rusting of welds and peeling of paint surfaces after six months of sea transportation, and rusting of beams can directly shorten the service life of the entire vehicle. To solve the problem of frequent maintenance for overseas customers in the later stage, all trailers sent to Nigeria, Ghana, and Angola undergo a standardized three-layer anti-corrosion coating process before leaving the factory.
The first step is to perform shot blasting and rust removal on the entire vehicle, deeply polishing all steel structures such as beams, bottom plates, and brackets to remove rust and oxide layers on the steel plate surface, enhance coating adhesion, and prevent primer hollowing and peeling off; The second step is to fully cover and spray epoxy zinc rich primer, with a focus on reinforcing weld seams, chassis gaps, and other corrosion prone blind spots, forming a dense anti rust isolation layer to isolate seawater and rainwater erosion; The third step is to thicken the wear-resistant topcoat and spray it, which has the ability to resist UV rays and gravel scratches. It is not easy to crack or fade even after prolonged exposure to sunlight and bumpy driving.
In the on-site workshop, low flatbed trucks and dump trucks are neatly arranged, and workers meticulously handle every hidden point without any missed or thin spraying. Three layers of anti-corrosion and layer by layer protection greatly enhance the overall corrosion resistance of the vehicle. Even after long-term roll on/roll off shipping and long-distance transportation in high salt spray cabins, there will be no large areas of rust after landing.
Many long-term cooperative logistics customers in West Africa have provided feedback that trailers with three-layer anti-corrosion technology, which have been put into operation in mining areas and construction sites for more than two years, still have intact frames. Compared to simple spray painted models, this significantly reduces the implicit costs of rust removal, paint repair, and beam replacement.
At present, all the spraying processes of this batch of trailers have passed the acceptance inspection. The next step is to complete the assembly of suspension, axle, and hydraulic ladder. After the quality inspection is completed, they will be uniformly arranged to be shipped to West Africa. Our factory will continue to adjust anti-corrosion facilities according to different regional climates, and create durable and low-cost transport trailers for overseas fleets.
