Frame: A space frame structure formed by welding of longitudinal beams and integral through beams. It can balance the strength, rigidity, toughness and bearing capacity of the frame without permanent deformation.

The series of grid-type semi-trailer frames are all through beams, and the longitudinal beams are straight and gooseneck. The height of the longitudinal beam is from 400mm to 450mm, and it is welded by high-strength board using automatic ambush welding. The frame is shot blasted to improve the surface strength.
