A twenty-foot container carries roughly 900 to 1,100 square metres of engineered timber depending on box format and packing density. A forty-foot high-cube carries 2,000 to 2,400. Vinyl and hybrid pack differently — heavier per box, higher volumetric density.
Container releases are planned against site absorption. A tower unable to accept a full forty-foot drop needs either a split release, a bond store staging point, or a smaller container. Each option has a freight cost implication that is priced at procurement, not at dispatch.
Staged programmes benefit from container sizing that matches the fit-out draw — three sequential twenty-foots against three towers is typically better sequenced than a single large drop that then requires site rehandling.
