Boxed Trough Chassis with Fabricated Metal Chassis Assembly and Formed Ribs

Shanghai Hanshen (Shanghai, founded 1991) fabricates metal chassis assemblies with boxed trough form and formed ribs using gantry milling, four-axis horizontal machining, and boring and milling machining at their north of 35,000 m² Shanghai facility; rib pitch and trough base flatness are both verified per your drawing requirements at initial sample, so components seated in the trough align to a consistent reference plane and formed ribs provide the correct bending stiffness at design load. Formed rib pitch, base flatness, and hole positions are recorded on the dimensional report before goods-out. EN 1090 and ISO 3834 certifications govern structural execution and welding quality for energy storage, machinery manufacturing, railway, and general industry fabricated metal chassis assembly applications, serving elevator and escalator, logistics, and instrumentation applications. We can quote once we have trough dimensions, rib profile, hole positions, and material grade from your drawing. For a cost estimate from our shanghai team.
