Standard containers force compromise: barriers stacked loose, hoarding board scuffed against bare steel, a unit sitting half empty because the panel pitch does not divide into it. We start from your actual equipment — panel dimensions, foot profile, weight, and how many items a crew can realistically handle in one movement — and size the stillage to a whole number of items.
That number matters more than it sounds. When a unit holds a known count, the yard picks a load by counting stillages rather than counting panels, the truck plan is fixed rather than estimated, and a shortage shows up on the loading dock instead of on site at six in the morning.
Where an inventory is mixed — barriers one week, fencing the next — we design to the largest item and add internal division or removable posts, so the same unit works across several product lines rather than sitting in a corner between shows.
