TECHNICAL 19 · PROCESS

From enquiry to container: what happens, in what order, and who does what.

A frame order has six stages. Most delays come from two of them: a drawing that changes after the material is cut, and a payment that lands after the vessel is booked.

Hot-dip adds days to production; it is a separate process, not a step in the line.

What can move a date

  • A drawing change after material is cut — the most expensive delay.
  • A payment that arrives after the vessel booking — the container is rolled.
  • A coating change from pre-galvanised to hot-dip — re-sequencing, not just re-pricing.
  • A quantity change under 5 t — the mill may not schedule a small heat.

Our commitment

We state a date range in the quotation, not a single date, and we tell you when a stage slips rather than at the end. If a vessel is missed we will say so and propose the next one.
