Key Notes:
• Customization: Dimensions (length: 12.5m/13m), payload, and materials vary by manufacturer and regional road regulations.
• Material Advancement: High-strength steel (e.g., Q345) reduces curb weight while maintaining load capacity.
• Safety & Comfort: Air suspension minimizes cargo shock; ABS/EBS ensure braking stability.
• Application-Centric: Stake trailers for bulk/irregular goods; side wall trailers for general cargo; van trailers for enclosed/temperature-controlled transport.
