Engineering input
Cargo dimensions, operating weight, route, loading method, tractor interface and destination requirements define the design brief.
Commercial overview
Semi-trailer manufacturing process
A controlled sequence from buyer requirements and drawings to fabrication, assembly, finishing and documented pre-shipment review.
Fabrication and assembly
Steel preparation, frame fabrication, welding, axle and suspension installation, electrical work and functional systems follow the approved production file.
Finishing and release
Surface treatment, paint, markings, functional checks and shipping preparation are reviewed against agreed inspection points.
Confirmed manufacturing framework
Production is based in Jinan, China. Projects can be configured from 12 to 24 metres in length with custom height to the approved specification. MOQ starts from 3 units, and typical production time is approximately 3 weeks after technical and commercial approval.
Components, supply format and control
Axles, suspension, brakes and other components can use Ultima/OEM Chinese solutions or established brands. Every model can be evaluated as a complete trailer, private-label OEM, CKD, SKD or component supply. Agreed inspection points, production photos and final pre-shipment inspection are documented.
Warranty, certificates and logistics
Factory-completed units carry a 12-month warranty on main assemblies. Locally assembled projects do not carry a blanket factory warranty on the finished unit; component and assembly responsibilities are defined in the contract. Certificate documents are available for review and confirmed per destination. Freight and vessel arrangements can be coordinated with logistics partners.
