Overview


Designed for high-value and weather-sensitive cargo, the Enclosed Side Wall Cargo Semi-Trailer offers superior security and protection during transit. With a fully enclosed steel structure and airtight seals, this trailer ensures 100% protection against dust, water, and unauthorized access, making it ideal for electronics, automotive parts, and consumer goods requiring controlled transport environments.


Features


Secure Enclosed Design

Full Steel Enclosure: 2mm galvanized steel side walls + roof (corrugated profile, 200N/m² impact resistance), with recessed door hinges and tamper-evident seals (break strength 500N), reducing cargo theft risk by 90%.

Weatherproof Sealing: EPDM rubber gaskets (5mm thickness, compression force 15N/mm) around doors and panels, achieving IP65 water/dust ingress protection—tested at 100kPa water pressure (equivalent to heavy rain).


Climate Control Options

Insulated Interior (Optional): 50mm polyurethane foam insulation (thermal conductivity 0.025 W/m·K) with vapor barrier, maintaining interior temperature ±5°C of set point (10–30°C range), ideal for electronics and pharmaceuticals.

Ventilation System: Roof-mounted louvers (100mm diameter, 10pcs) with insect screens, enabling 500m³/hour air exchange to prevent condensation in high-humidity environments.


Efficient Loading Systems

Power-Operated Roll-Up Doors: 4m wide x 3m tall aluminum doors (motorized, 0.5m/s opening speed), compatible with forklift access and container loading systems (ISO 668 compliant).

Load Tracking Sensors (Optional): IoT-enabled weight sensors (±0.5% accuracy) and door-opening alarms, transmitting real-time data to fleet management software (e.g., Geotab, Trimble).


High-Strength Lightweight Design

Aluminum-steel Composite Frame: Steel main beams (Q345B) + aluminum side panels, reducing tare weight by 15% (18,000kg vs. 21,000kg all-steel trailers) without compromising structural integrity (40-ton payload capacity).

Aerodynamic Profile: Rounded front fascia and flush-mount side panels, reducing drag coefficient by 12% (Cd=0.75) for improved fuel efficiency on highway routes.


Application


Electronics Logistics: Transports server racks, LCD panels, and automotive ECUs with zero dust ingress, compliant with IPC-A-610 class 3 cleanliness standards.

Retail & E-Commerce: Safely delivers appliances, furniture, and clothing in all weather conditions, with optional anti-static interior coating (surface resistance <10^9Ω) for sensitive electronics.

Automotive Industry: Hauls engine components, transmission parts, and finished vehicles between factories and distribution centers, with load-securing tracks (10,000N/m linear load) for preventing cargo shift.


Why Choose Us


Security Leadership: The only enclosed trailer in its class to pass VPG 11 (vehicle penetration resistance) and EN 16683 (freight security) certifications, trusted by luxury brands and pharmaceutical distributors.

Multi-Temp Capability: Optional heating/cooling units (5kW capacity) for temperature-sensitive cargo, maintaining 2–8°C for medical supplies or 15–25°C for automotive interiors.

Total Cost of Ownership: 20% lower insurance premiums due to enhanced security features, combined with a 5-year warranty on seals and door mechanisms.
