Video transcript

  1. 0:00Every two-piece tin starts as a flat tinplate sheet.
  2. 0:05'Standard tinplate' isn't a spec: quotes don't compare, lids misfit, tins dent. Specify thickness in millimetres, temper and tin coating.
  3. 0:15Cost and weight rise in step with thickness, but a flat panel's stiffness grows with the cube. Big flat lids dent first; small round tins lean on shape.
