Key Applications：

For safe, clean bulk transport, the 40CBM stainless steel tanker semi trailer is a solid choice for most industries. It’s got strong corrosion resistance, good airtightness and plenty of loading space—practical and reliable, no fancy stuff. It’s usually used to haul food-grade liquids, non-highly corrosive chemicals, drinking and industrial water, petroleum products, dry bulk (with a pneumatic system), and even pharmaceutical or cosmetic ingredients, supporting different sectors with steady transport.

Technical Specifications：

Quality Inspection Before Delivery：

 At LUYI AUTO, every semi-trailer goes through strict pre-delivery checks to guarantee reliability. Our technicians inspect welding quality, main beam dimensions, and structural strength one by one. We test axle, suspension, braking, and lighting systems to ensure full functionality. We also verify surface finish, anti-rust treatment, and accessory completeness. Only units passing all items get approval. We keep complete inspection records for traceability, so customers receive safe, durable trailers that meet export standards.

Packaging and Shipping：

 The semi-trailer is treated with anti-rust wax and marine paint for rust protection. Small parts are packed in cartons or wooden boxes and securely fixed. The vehicle is shipped by RO-RO, flat rack or bulk carrier from main Chinese ports. Before shipment, full inspection will be conducted. We provide complete shipping documents and can arrange door-to-door service. Lead time is 15–30 working days after deposit.
