40FT 3 Axle Side Wall Semi Trailer with High Side Panels

The RoadKing 40FT 3 Axle Side Wall Semi Trailer with High Side Panels is a high-volume cargo trailer engineered for high-density bulk goods, agricultural yields, construction materials, and general logistics. Featuring a full 40-foot flatbed deck paired with customizable high side panels (ranging from 600mm to 1700mm), this trailer maximizes volumetric cargo capacity while preventing spillages and shifting during high-speed long-distance transit.

Built on a robot-welded, high-tensile Q345 / T700 steel chassis, this semi-trailer delivers a heavy-duty payload rating of up to 80 tons. The side walls feature modular, drop-down, or fully removable panel designs, giving fleet operators the flexibility to load via forklifts or cranes. Whether transporting bagged cement, fertilizers, grain, timber, or steel coils, this 40FT side wall trailer provides exceptional versatility across rugged road networks.

Widely deployed across demanding transport routes in Africa, Southeast Asia, South America, and the Middle East, RoadKing's high panel side wall trailers offer exceptional structural durability, low operational downtime, and a high return on investment (ROI).

Key Technical Advantages

• Customizable High Side Panels (600mm – 1700mm)

  Engineered with reinforced steel panel height options to suit low-density, high-volume cargo (like agricultural products or bagged goods), ensuring maximum load security and containment.

• Heavy-Duty High-Tensile Steel Structure

  Manufactured using Q345/T700 high-strength steel main I-beams and heavy crossmembers, offering maximum resistance against frame twisting and deck sag under extreme point loads.

• Multi-Functional Foldable & Removable Wall System

  Side panels can be quickly unlatched and folded down or detached entirely, converting the high-panel trailer into an open flatbed for side-loading oversized cargo or steel products.

• Proven 3-Axle Suspension & Axle Options

  Fitted with 13T–16T heavy-duty axles (FUWA, BPW, or SAF) and heavy-duty mechanical leaf spring or air suspension, providing smooth highway tracking and uniform tire wear.

• Durable Anti-Corrosion Finish

  Fully shot-blasted before applying high-grade primer and powder coating/polyurethane finish, offering long-lasting protection against rust, weather, and abrasion.
