3 Axle Low Flatbed Semi Trailer

Heavy-Duty Carbon Steel Construction

This 3 axle low flatbed semi trailer is independently assembled by HUAYU with the entire body welded from high-strength carbon steel. The main structural steel plate is 15mm thick — that is heavier plate than most standard flatbed trailers use, and the extra thickness gives the deck and frame enough rigidity to carry 80 tons without the deflection and permanent bending that thinner plates develop under repeated heavy loading.

The three axles are FUWA brand, and the landing gear and king pin are both JOST brand. FUWA axles are the most widely used axle brand in Chinese-manufactured trailers for export, with parts and service available across Africa, Southeast Asia, and the Middle East. The 80-ton carrying capacity handles a wide range of heavy products — construction machinery, steel bundles, industrial equipment, and oversized components.

This low flatbed semi trailer adapts to various road conditions because the 15mm steel plate distributes point loads from tracked equipment and heavy concentrated cargo across a wider area of the frame. Where lighter trailers develop stress cracks under the same loads, this plate thickness keeps the deck flat over years of service.

JOST Support Legs and Frame Quality

The entire vehicle structure of this HUAYU 3 axle low flatbed semi trailer is high-strength steel plate throughout — main beams, cross members, and deck are all the same grade of carbon steel. That consistency matters because mixed steel grades create weak points at the junctions where different materials meet. When every structural element is the same grade, the frame responds to load stress uniformly and avoids the localized fatigue failures that mixed-material frames develop.
