Yes, absolutely. As a manufacturer, we have a professional engineering team. We can customize the dimensions, loading capacity (e.g., 60 tons, 80 tons), axle brand (FUWA/BPW), suspension type, and paint color to suit your specific road conditions and transport needs.
We use high-strength Q355 or T700 steel for the main beam. This ensures the trailer is lightweight yet strong enough to withstand heavy loads and rough road conditions in Africa and Central Asia.
Standard models usually take 15-20 working days after receiving the deposit. For urgent orders, we can even shorten it to 10 days. We will keep you updated with photos and videos during production.
Our standard term is T/T (30% deposit, 70% balance before shipping). For large orders, L/C (Letter of Credit) is also negotiable.
Yes, we provide a 24-month warranty for the main beam. For spare parts (like brake pads, lights), we supply original parts at factory cost for the lifetime of the trailer.
At Kales Vehicle, we understand that shipping costs are a major part of your investment. That’s why we offer multiple transport options tailored to your destination and budget.
Whether you choose Container Shipping for protection, Ro-Ro (Roll-on/Roll-off) for speed, or Bulk Cargo for cost savings, we ensure every trailer is handled with care. All vehicles undergo rigorous wax spraying and are covered with waterproof tarpaulins before shipment to prevent seawater corrosion during transit. We calculate the optimal stacking method (e.g., 3 units stacked together) to help you minimize freight costs.
