Specialised containers
ISO tank container specifications, plus side-open, double-door and modified units: offices, living units and stores.


Beyond the standard box we supply ISO tank containers for liquids, side-open units for forklift loading along the length, double-door units that open at both ends, and modified shells: a modified site office, living units, storage with extra doors, insulation, wiring and paint.
The tank figures below are the reference for the 20′ tank. Side-open and double-door units share the dry-container footprint of their size (see the 20ft dry container). Modified units are quoted against the drawing you send us.
Typical uses
- Liquids in bulk: chemical grade or food grade
- Forklift loading along the side
- Site offices, living units and stores
