Technical Specifications

Built for the Long Haul: High-Tensile Steel Chassis

The foundation of any reliable trailer is its frame. Our 40ft high sidewall trailers are constructed using Q345B high-tensile steel with reinforced "I" beams. Unlike standard trailers that suffer from structural fatigue, we utilize automated submerged arc welding to ensure every joint is seamless and crack-resistant. This robust architecture allows for a steady 60-80 ton load capacity, ensuring your fleet handles heavy cargo without compromising safety or vehicle lifespan.

Customizable Sidewalls for Maximum Versatility

Logistics needs change, and your equipment should adapt. We offer customizable side wall heights ranging from 600mm to 1200mm to suit specific cargo volumes. The sideboards are engineered with a user-friendly locking mechanism and can be fully removed. This modularity allows you to switch from a high-side grain hauler to a standard flatbed for container transport in minutes, significantly increasing your equipment's utilization rate and ROI.

Premium Drivetrain: FUWA Axles & Mechanical Suspension

To minimize downtime, we integrate globally recognized components. Each trailer features genuine FUWA or BPW axles paired with a heavy-duty mechanical leaf spring suspension. This setup is specifically optimized for off-road or poorly paved conditions common in international transport. The inclusion of JOST landing gear and a dual-line braking system ensures that your 40ft cargo trailer remains stable during loading and provides responsive stopping power when fully leveraged.

Advanced Anti-Corrosion Treatment for Longevity

Environmental wear is the silent killer of semi-trailers. Our manufacturing process includes a comprehensive sandblasting treatment to remove all oxidation before painting. We apply a high-grade polyurethane finish over an electrophoretic primer. This multi-layer protection ensures your 40ft sidewall trailer resists rust and salt-spray corrosion for years, maintaining its structural strength and resale value even in tropical or coastal climates.
