Aluminum alloy plates are replacing steel as the preferred material for trailer manufacturing due to their lightweight and high strength. The density of 6061-T6 aluminum alloy plate is only 1/3 of that of steel, and its tensile strength is ≥290MPa. It can reduce the weight of the trailer by 30%, increase the single load by 15%, and reduce fuel consumption by 12%.
Comparison of aluminum plate VS steel performance
Dimensions Aluminum alloy plate (6061-T6) Hot-rolled steel plate (Q345)
Weight 2.7g/cm³ 7.85g/cm³
Corrosion resistance Salt spray resistance for 2000h after anodizing↑ Regular rust prevention is required after the galvanized layer is damaged
Processing efficiency Cutting energy consumption is reduced by 40% Plasma/laser cutting is required
GNEE aluminum plate solution
GNEE mass-produces 6 series aluminum alloy trailer special plates, which have passed ASTM B209 certification, with a thickness of 1.5-8mm, and customized surface treatment (PE/PVDF coating) to extend the service life to 20 years.
Four major advantages of light aluminum trailers
Weight reduction and efficiency improvement: 15-meter cargo compartment uses 3mm aluminum plate instead of steel, reducing weight by 1.2 tons and saving more than 50,000 yuan in fuel costs annually;
Corrosion resistance: The service life is extended by 3 times in marine transportation scenarios, and the maintenance cost is reduced by 60%;
Recyclable: The scrap recycling residual value rate reaches 75%, which complies with the EU ELV Directive;
Flexible design: Supports roll-forming of complex curved surfaces and is compatible with special trailers such as refrigerated/hazardous chemicals.
GNEE customized service
GNEE provides a full range of aluminum plates with hardness of H22-H32, supports laser engraving of anti-counterfeiting logos, delivers samples within 72 hours, and has a monthly production capacity of over 8,000 tons.
Breakthrough in trailer aluminum plate technology
Continuous extrusion technology: grain size reaches level 7 (ASTM E112), plate surface flatness error <0.1mm/m; Nano coating: Cerakote ceramic coating is used, wear resistance is increased by 50%, and it can adapt to extreme environments from -40℃ to 120℃; Intelligent detection: online X-ray flaw detection, defect detection rate 99.99%. GNEE intelligent manufacturing strength
GNEE has built a fully automatic heat treatment line with a temperature control accuracy of ±1.5℃ and obtained IATF 16949 automotive-grade certification.
