42000L Diesel Oil Aluminum Tanker Semi Trailer

HUAYU 42000L Diesel Oil Aluminum Tanker Semi Trailer

This 42000L diesel oil aluminum tanker semi trailer is independently processed by HUAYU with all-aluminum alloy tank body and manhole cover construction. Dimensions are 10,600mm x 2,550mm x 3,750mm, and the six-compartment layout supports multi-product delivery of gasoline, diesel, and jet fuel in a single trip. Discharging valves come in 3 or 4 inch diameter to match the buyer's loading infrastructure. If you are buying a fuel tank trailer for your fleet, understanding the valve and compartment options upfront saves time.

The main beams use a welded design or special I-beam connected by bolts and nuts in Q355 carbon steel. Aluminum for the tank, carbon steel for the frame — that combination gives you light tare weight where it counts (the tank body) and high structural strength where it matters (the load-bearing frame). Q355 is a step above the Q345 commonly used in budget tankers, offering better yield strength under sustained loads.

Welding and Tank Construction

The tank body is manufactured using TIG welding, with weld quality rated over 99% as verified through quality inspections. Internal partitions, wave deflectors, and semi-trailer support structures use metal materials that maintain the overall structural strength of the trailer. Wave deflectors inside the tank control liquid surge during braking and cornering — without them, a 42,000-liter fuel load generates enough momentum to shift the trailer's center of gravity and affect braking stability.

BPW axles (3 axles, 13T each) and BPW braking systems are standard on this aluminum tanker semi trailer. JOST landing gear supports the trailer at rest, and the connection to the tractor uses a JOST 2.0 or 3.5 inch bolt-in king pin. Mechanical suspension is the standard configuration.

HUAYU pairs the high-strength support structure with JOST landing gear across this model. Exterior color and spray coating are customizable, so operators can match fleet branding or comply with local tanker visibility regulations. Contact us to discuss custom specifications.
