Design Stackable Industrial MS Containers

I’m looking to get two mild-steel, powder-coated containers engineered for day-to-day use on our manufacturing line. Container 1 • Overall size: 1030 × 1250 × 1160 mm • Rated load: 1 000 ton • Includes a fully removable cage for quick access and cleaning Container 2 • Overall size: 1170 × 1200 × 150 mm • Rated load: 1 000 ton • Low-profile, open-top tray style Both units must stack safely—loaded or empty—so the design has to integrate interlocking feet or a similar stabilising feature without adding excessive weight or complexity. What I need from you 1. 3D CAD models (STEP or SolidWorks preferred) 2. Fabrication-ready 2D drawings with weld symbols, material specs, and coating notes 3. Basic structural calculations or FEA screenshots proving the 1 000-ton capacity 4. Bill of materials with finish and hardware details Acceptance criteria • All dimensions and load ratings met exactly as listed above • Stackability verified through modelling or calculations • Drawings delivered in PDF and native CAD formats, ready for workshop use • Components specified in mild steel (MS) with clear powder-coat colour and thickness call-outs If you have prior experience designing heavy-duty, stackable manufacturing containers, I’d like to see a quick sample from your portfolio when you reply.
