Fence Semi Trailer

Product Overview: Engineered for Global Logistics
Our fence semi-trailers are precision-engineered for the long-haul transportation of bulk cargo and heavy-duty freight. Built with high-strength alloy steel, these trailers feature an optimized load-bearing structure and flexible sidewall configurations, perfectly balancing cargo security with efficient loading and unloading.
Unlike standard flatbed trailers, our integrated fence structure effectively prevents lateral cargo shifting, making these units the gold standard for:
Industrial: Steel products, construction materials, and industrial equipment.
Agricultural/Bulk: Bagged goods and harvested produce.
The open-platform design permits forklift and crane access from all directions, significantly improving loading productivity. We have successfully exported these trailers to various regions worldwide, providing customized road-legal configurations tailored to meet specific local axle load regulations and operational environments.

High-Strength Frame Structure
Material: Main beams and critical load-bearing components are manufactured from Q345B high-strength alloy steel, chosen for its superior yield strength and bending resistance.
Welding Technology: Main beams are fabricated using automatic submerged arc welding. All critical welds undergo ultrasonic flaw detection to ensure structural integrity under heavy-duty, high-frequency vibration.
Torsional Rigidity: The frame's web and flange plates are reinforced with additional gusset plates at stress points, effectively preventing metal fatigue and deformation even under challenging road conditions.

Fence System & Sidewall Engineering
Customization: Sidewall heights are tailored to cargo density (600mm – 1800mm).
Vertical Posts: Engineered from cold-formed structural steel, secured via interlocking connections and high-tensile bolts to maintain wall rigidity under maximum loads.
Flexibility: Options include fully detachable, semi-removable, or fixed configurations. Sidewalls feature a corrugated steel design, offering superior impact resistance and structural stability compared to flat panels.

Suspension & Load-Bearing Systems
Axle Configurations: Available in 2, 3, or 4-axle setups to ensure compliance with regional axle-load regulations.
2 Axle: 25-40 tons capacity (Medium-duty logistics).
3 Axle: The industry standard for international trade (40-60 tons capacity).
4 Axle: Heavy-duty configuration (70-100 tons capacity for mining or industrial machinery).

Suspension Options:
Mechanical Spring Suspension: A simple, robust design optimized for rough terrains and low-maintenance operations.
Air Suspension: Provides enhanced shock absorption, protecting sensitive cargo and reducing road-to-vehicle vibration, which significantly extends tire service life.

To ensure global reliability, all trailers are manufactured in strict compliance with ISO 9001 standards.
Axle Brands: High-performance options including FUWA, BPW, or equivalent, designed for long service intervals.
Braking System: Dual-line pneumatic braking with optional WABCO valves and ABS systems to ensure maximum stability on steep descents.
Landing Gear: Heavy-duty reinforced landing gear with a static load capacity exceeding 50 tons.
Tires: Standardized for heavy haulage, including 12R22.5, 315/80R22.5, or 12.00R20 radial tubeless tires.

Our standardized production flow guarantees unmatched reliability:
Cutting: High-precision CNC plasma cutting ensures component tolerances within 1mm.
Welding: A hybrid of gas-shielded and submerged arc welding ensures clean, durable seams.
Surface Treatment: The entire chassis undergoes professional shot blasting to remove rust and scale, followed by a high-quality primer and polyurethane topcoat for long-term corrosion resistance.

Inspection: Every unit undergoes rigorous testing, including frame alignment checks, brake system pressure testing, and electrical circuit verification prior to dispatch.
