II. Non-standard Custom Sizes In addition to standard sizes, container houses can be customized according to needs. The common adjustment ranges include:

  1. Width: Options such as 2.5m, 2.55m, 3m, 4m, etc.;
  2. Height: Options such as 2.6m, 2.7m, 2.8m, 2.9m, etc.;
  3. Length: Common custom lengths are 3m, 6m, 8m, 12m, etc., for example, combinations like 3m×6m, 3m×8m, 3m×12m.

III. Special Type Sizes

  1. Open-top Containers: The top is open, facilitating the loading of ultra-high cargo. For example, the internal dimensions of a 20-foot open-top container are Length 5890mm, Width 2320mm, Height 2310mm; the internal dimensions of a 40-foot open-top container are Length 12010mm, Width 2330mm, Height 2150mm.
  2. Flat-rack Containers: The bottom is flat, suitable for transporting overweight cargo. For example, the internal dimensions of a 20-foot flat-rack container are Length 5850mm, Width 2230mm, Height 2150mm; the internal dimensions of a 40-foot flat-rack container are Length 12050mm, Width 2120mm, Height 1960mm.

IV. Size Selection Recommendations

  1. If rapid deployment is required and the space requirements are clear, prioritize standard 20-foot or 40-foot container houses;
  2. If the site is limited or special functions (such as ultra-high or ultra-wide) are needed, consider non-standard custom sizes;
  3. Special types (such as open-top containers and flat-rack containers) are suitable for specific cargo transportation needs and should be selected according to the actual use.
