• Welding: The main beam adopts automatic submerged arc welding. Welding current and voltage are precisely controlled to ensure weld penetration exceeding 12mm. Key stress nodes of the chassis are manually reinforced by experienced welders. Ultrasonic flaw detection eliminates welding defects, effectively enhancing structural torsion resistance and load-bearing performance.
• Coating: After degreasing and phosphating treatment, oxide scales and impurities are removed from the surface. Then, cathodic electrophoresis creates a uniform coating layer, ensuring long-term appearance preservation and excellent corrosion resistance in harsh environments, significantly extending service life.

• Main Beam Material: Made of Q345/T700 steel with excellent bending and torsion resistance.

• Customizable Length: Platform length can be customized based on transportation needs to improve cargo capacity and space utilization.
• Aluminum Alloy Sliding Rail System: Lightweight, wear-resistant, smooth opening, and easy forklift access from multiple angles, improving loading efficiency.

Q1: What advantages does a curtain side trailer have over a standard side wall trailer?
A: The main advantages are flexible loading/unloading and better cargo protection. The curtain can fully open for multi-direction forklift operations, and the sealed tarp provides protection from wind, rain, and dust, making it more suitable for appliances and FMCG goods.
Q2: How is the waterproof performance of the curtain trailer?
A: We use high-strength PVC tarp with a specialized waterproof design to ensure cargo is fully protected during rainy season transport.
Q3: Is it easy to replace damaged PVC tarpaulin? Do you provide spare parts?
A: Yes, it is easy to replace. The tarp uses a modular design, connected with buckles and sliding rails, which allows one person to remove it.
Q4: For transporting fragile goods, is mechanical or air suspension better?
A: Air suspension is recommended. Its shock absorption performance is 80% better than mechanical suspension, significantly reducing vibrations and damage to fragile goods such as appliances and furniture.
Q5: How long does it take from order to delivery for customized models?
A: Regular customization takes about 20-25 days, while special configurations take about 25-30 days. We will confirm production time in advance and provide full tracking to ensure timely delivery.
