Core Process
Welding: Automatic submerged arc welding technology is used to weld key load-bearing components such as main beams, ensuring the strength and consistency of the connections of major structural parts. Experienced technicians handle key stress nodes for fine processing. This technology ensures the integrity and durability of the whole vehicle structure, enhances the frame’s resistance to heavy load deformation, and guarantees long-term durability.
Painting: We use high-end electrophoretic coating technology. After degreasing and phosphating treatment, the vehicle body is immersed in the electrophoresis tank, allowing the protective coating to penetrate every tiny structural gap. Then, a surface topcoat with excellent weather resistance is sprayed, forming a hard and wear-resistant protective layer, providing long-term protection and an attractive appearance.

Main Features
Main Beam Material: Made of Q345/T700 high-strength steel and processed into an I-beam, maintaining structural stability under heavy loads and not easily bending.
Specification Customization: Customize different length, width, and height specifications according to customer needs, meeting loading requirements for different types of cargo.

Sliding Rail System: High-quality aluminum alloy rail, lightweight, wear-resistant, corrosion-resistant, and smooth sliding without jamming.
PVC Tarp: Made of high-quality PVC tarp with excellent waterproof, dust-proof, and UV-resistant performance, protecting cargo from dust and scratches.

Reinforced Rear Door: Reinforced rib design on rear door, tightly sealed when closed, improving stability during transportation.
Suspension Options: Provide both mechanical and air suspension. Air suspension, as an upgrade option, offers better shock absorption and effectively reduces cargo damage.

Spare Tire Rack Design: Reinforced spare tire rack design at the rear ensures quick handling of tire failure during long-distance transportation.
Safety Protection: Equipped with thickened rear anti-collision beam and high-brightness LED lights to reduce driving safety risks.


After-Sales Service
When purchasing our curtain side semi trailer, we will provide one year of free warranty service. Faults caused by manufacturing defects can enjoy free repair or parts replacement.
We provide lifelong supply of original genuine spare parts to ensure compatibility with the vehicle and help customers reduce maintenance costs.

FAQ
Q1: What advantages does the curtain side semi trailer have compared to a fence semi trailer?
A: The advantages are loading/unloading efficiency and cargo protection. The curtain can open completely, allowing forklifts to operate from multiple directions. The sealed tarpaulin is windproof, rainproof, and dustproof, making it more suitable for home appliances, food, and other goods that are easily damaged or affected by moisture.
Q2: How to ensure cargo safety during transportation on rainy days?
A: Our multi-layer composite tarp has excellent waterproof performance, combined with precise seam sealing technology and drainage design, ensuring reliable protection even in harsh weather conditions.
Q3: What key points should be noted in daily maintenance?
A: Focus on cleaning and lubricating the guide rail system and regularly inspecting and maintaining the tarp material. We provide detailed bilingual maintenance manuals and video guidance materials.
Q4: How long is the typical production and delivery cycle?
A: The production cycle for standard configuration products is 25-30 working days. Special customization projects need to be evaluated based on specific technical requirements, and we will provide an accurate schedule.
